The road to the temple reminds me of the county roads in east Texas. They're very narrow but almost all of them are paved. Most of the county roads in west Texas are just dirt or gravel, fun to ride my XT250 on but the bike gets very dusty. Your videos were making me want to try a one tooth larger front sprocket on my XT250 but I'm worried about affecting it's hill climbing ability. I just found out this week that Suzuki will be making the DR650 for a least another year so I'm going to trade in my XT for a new DR650 in the next few weeks. I lke the simplicity of the DR, it's air/oil cooled, has a carburetor (no electric fuel pump to go out), it's reliable as a hammer. I bought a new DR650 in 1998 and put almost 30,000 trouble free miles on it before I sold it.
Being from Oklahoma, I've been down in Texas a few times. There are several locations around where I live that resembles much of the USA. The only difference is this is the tropics, no winter weather.......
My daughter and fiancee bought two. I think he plans to do a big bore kit on his. I rode hers but didn't like the shifter, that would be the first thing I would change. Thanks for sharing.
All the small bikes here in Thailand use the toe/heel shifters and I've just gotten used to it by now. I use my toe on both of them, either shifting up with the heel or down with the toe, I've gotten use to it. Makes things a little hairy when I get on my Triumph though........
It would be nice to get some kick back from them, but I'm just showing what can be done with this bike to make your riding experience better where you live. If I'd of been in an area that was pretty much flat land, I'd probably leave it stone stock.... Who am I kidding, I' like Tim the Tool Man Taylor. I like more power..........
Plans are to run as short test on it tomorrow, still another week away from hitting the really tough mountain roads. I just want some time on the engine before hitting it hard.......
Ever since I got this bike, I've said the engine needs more power. Since then, I've been looking at big bore kits and gearing to see what will work best for my riding up here in Northern Thailand. I have to travel some distance to get up to the mountain ranges to visit the places we want to go see, so I still need to be able to run close to 90 KPH up to the mountain areas. Once I'm in the mountain areas, I need the engine to be able to pull from down low in the RPM range and allow me to run at least in 2nd gear up the twisty roads. I really thought the 14 tooth sprocket would be perfect if I could get some usable Torque and another pony out of the engine. I believe we are at that stage now, I'll be finding out in the next couple of days....... Thanks for the comment, glad to see you agree....... Adding to this comment, I put the 14T back on this morning and took it for a short ride. That is the sprocket that will stay on the bike now, it works really good.....
Your bike has a throaty mellow sound now that in my opinion sounds perfect👌. Cool to see your bike pass this small test. Can't wait to see the #14 do its thing.
Probably won't get a chance until tomorrow to do that, I've got business to take care of in Chiang Mai today, so I'll be doing it tomorrow..... I like the sound of the bike also.....
@@TeamDNFracing Something for us to look forward to 📽. Your bike at a side view is starting to look like a Dakar Rally with all the blacked out accessories. Wait until you throw some knobbies on it and that will complete the look... very cool 😎 👌
@@findingneutral Got to do it one SS check at a time. This month is the suspension and next month is the tires. That in my opinion will complete the bike for me. Then Adventure Rides will happen weekly to showcase the bike and Thailands beautiful country.......
it's not until you actually own a ct125 that you really don't know how down they are on power till they see your first hill -and it doesn't have to be much of a hill either. i was pretty impressed how your bike pulled that hill especially when you rode back down as it really showed the grade in more detail. pretty sure your on a winner there and when you drop to that 14t front-look out warro...lol all the best eddie!
I've been saying it since I got the bike that it needs more power, not a lot, but a few more cc's and it will be just fine. Ol' Warro won't be able to stay with me on the hi way, but I guarantee, his will climb those hills. It's two different worlds that we ride in. One, he doesn't have the inexpensive access to the accessories like I do here, I'm pretty sure he would put this kit on if it didn't cost him an arm and a leg. For around $30.00 US he did what works for his riding area. It just wouldn't do for me here, I needed to be able to ride 75 to 80 KPH for some distance before I get to the really steep stuff, he only has a couple Kilometers to go and he's in riding heaven. ( I wrote all of this before I realized who made the comment) You've done your bike proud Graham, keep up the good work.......
@@TeamDNFracing your spot on with your thoughts too. if i were your way i'd done exactly the same. why play with sprockets when you can have the whole meal deal...lol if you can instal the big bore kit yourself or have a handy mate who can its still a very good proposition to do.
@@ridewithwarro I can tell one thing for sure Graham, I couldn't have done this to the bike in the US. The kit alone would have been several hundred dollars and then probably another 2 hundred to get it installed. However, if I were in the US, I'd have my tools and wouldn't have to have someone do it.......
@@TeamDNFracing 'd say here in oz for $200 they wouldn't even roll the bike in to their workshop to start on it so you got a real bargain fit there. plus what they would slug you for the parts alone.....lol after you do your testing you should offer a service- pack those kits up yourself and slap $50US on them for your trouble putting it togeter and post them out! after-all you thought of it! that would help you out a bit accessory wise and more importantly save the potentialk buyer lots of $$$ theres a very big saving in that kit of yours-i think you should think about it
@@ridewithwarro I retired 7 years ago Graham. At that time I swore I'd never have another job, that sounds like a job. Do you want a kit? I'd help you get one, but I don't want to do it for money......
I installed the 14T sprocket this morning and I did a video on how I change them out, because of your comment. Thanks for the comment and I should have done this video a long time ago......
The 15 tooth sprocket also might regain some of the lost fuel efficiency with employing the big bore kit and sure would seem to be the best combination for the highway rides leading to the trail rides. Question being of course does it underperform compared to the 13 or 14 when on tough trails and hills. From your ride today, the 15 tooth handled that temple hill, no problem. All depends I guess what you value the greatest but either way, this is a no lose endeavor. This bike handles and performs great, pure fun. Thanks.
I'm going to be doing some extensive testing with the 14T sprocket on it and if I've got nothing to do some time, I'll go back to the 15T and see just what it will do in the tougher riding areas. I really doubt that I'll ever go back to the 13T now as it just hurts the top speed to much and I don't like revving the little engine up to much.......
Fuel injection sure makes that engine perform smooth. They are just now hitting California and I only see them in red. I want the color you have so I guess I will have to wait. I went to that Shopee website but seems they don't ship to USA. I really can't find the parts I want for my 1982 Honda C70 Passport and Shopee has some really nice goodies. Do you have any suggestions on what I can do?
I'm not sure of all the problems the US market is having getting parts. I know that Shopee is not shipping to the US, but a company called Beez or something like that does ship there. Look in the FB site Honda CT125 Owners group and ask there. That is how some of my subscribers have found parts...... Good luck.....
I haven't gone on a ride with it since I've installed the BB Kit. Most everything so far is just personal ride tests alone. It will probably be another couple weeks before we do another group ride, I should be able to stay a lot closer to them......
@@TeamDNFracing I'm looking forward to it. I love all these videos, Thailand is beautiful and I want to visit there sometime for a break and some culture shock. I've lived in California my whole life but would like to experience something new. Anyways, keep them coming!
@@negachin2334 Then you definitely need to plan a trip to Thailand. When you do visit, go off grid to enjoy the real Thailand and not the tourist places that really aren't what Thailand is all about.......
@@negachin2334 A good GPS and reliable bike and you should be able to navigate around fairly well. It also might be a good idea to speak some Thai......
We currently have no plans to put a larger BBK in any of our bikes in the group, so we really haven't even searched for them. I know there are some 162cc & 181cc kits here in Thailand that are made for the Honda Wave 125i, which should fit the Honda CT 125 Gen 1 engines but there currently isn't any for the Gen 2 engined bikes here. As for sending a link, I'd have to do some serious research on them before I'd recommend either of those two kits. I've heard the 162 cc kit is pretty good, but we have not researched them at all. As for the 181cc kits, I've heard they like to go BOOM. Could be because most of the people here who put that kit in their bikes use them in drag races..... We may in the future do another build on a Gen 1 CT125 and when we do, it will probably get the 162cc kit in it, which means I'll be doing some serious research before we settle on a particular kit. As of now, there are a few Japanese companies that sell the BBK's for the Gen 1 CT and you can find the names and web sites for them on the Internet. Use the Honda CT125 in the search bar when looking..... I really can't tell you any more because we haven't spent any time on anything bigger than the 143cc kits we are using....
I enjoy your videos. I would be interested in the top end on pavement as well as torque on the hills. Gas mileage would be great to know. My concern with the bigger cylinder is over heating. I am planning on doing the Transamerican trail. I need to have the torque for Colorado and speed for detours and paved road portions. My ct90 won't do it. I am excited to pickup my ct125 next weekend.
Thinking about doing at least part of the TA as well when i get mine after Feb. I’d like to stay away from highways all together. At least 55mph or less. Mississippi looked awesome.
@@mattp9029 yeah. It looks like a lot of the Eastern trail is on roads. I'm up in Wisconsin and plan on doing a side trail Steve put together from la Crosse to Iowa. I will get a second 125 for my fiance. She has to learn to ride and do trail riding. When do you think you will get out on the trails?
Looks like you guys are going to be having some fun for sure on the Transamerica trail. Top speed is right at 60MPH for this bike stock, don't know as yet with the BB kit in it. Torque on the hills is not quite enough for higher mountain areas, but adequate for normal hills in the stock form. Fuel economy is really good on this bike stock. I got on average of 60 KPL on most of my Adventure rides. Have not had the Big Bore Kit on long enough to do a fuel economy run. Will be doing it next week......
@@TeamDNFracing I can't wait to see more videos. I, too, like the views and trips you take with the bike. I've been to Korea but not Thailand - beautiful country.
@@helowzrd Not sure yet. Likely sometime late spring early summer. The route you describe sounds good too. IdealIy I am looking for a loop...my dealer is saying my bike will arrive in Feb. We'll see...
Have been really enjoying your video clips, thank you! Still waiting for my CT125 here in New Zealand. It's been ordered since August, so I am hoping Santa may deliver to finish 2020 on a happy note. Very best wishes, Mike.
I went rhrough all your videos almost in a day. Extremely cool content. I love Thailand as well and would want to tour the country on bikes. When the ct125 gets released in the colorway like yours here in the US will pick up a couple for me and my sons. Quick question, will running your bike almost at prolonged highway speeds with the big bore overheat or damage long term? Planning to do long distance runs. Thanks for the uploads keep it coming!
I'm sure that if you run it for a long time at highway speeds, it will probably overheat. I don't run mine at really high speeds for any length of time, I'm not going on extremely long trips. Just short day trips up into the mountains......
If modding for power if your hope you should see what people are doing to the Grom, which has the same engine. I don't know how much tuning information there is for the CT, but what is available for the Grom will blow your mind.
I'm interested in how balanced the engine is with the bigger bore that and the mileage. Back in my day I had a Triumph Bonneville ... it would vibrate it''s nuts and bolts off if I cruised over 55 mph. My little Honda CL125 twin just purred and did 70 mph .. I never thought about gas .. did over 100 miles of power line roads in Arizona on less than a tank. Did you say one really needs a bigger bore exhaust with this upgrade? I don't see a listing from Honda on this kit. Could you tell us what kit you used and there? There seem to be a number of kits that will fit. Your videos are really a big help.
Good questions: The engine is typical Honda with little or no vibration, even after installing the BB Kit. The fuel economy in stock form is on average 60KPL (Kilometers Per Liter) on all of my Adventure rides so far. Have not done a fuel economy run with the BB Kit yet. If you put the BB Kit on your bike, to get the full benefit of power available, HP & Torque, put a good free flowing air filter like a K&N and a less restrictive exhaust system on it. I have installed an SKA air filter, a Diablo full exhaust system to go with my big bore kit. This BB Kit is not from Honda, it has Genuine Honda parts in it, but is a kit put together by an after market speed shop here in Thailand. They do not ship over seas, someone has already tried. There are many kits that will fit this bike. The Grom, Monkey and Super Cub all have the same top end as the CT125. A hop up kit for one of them would fit the CT125 just fine. Make sure any kit you get has the larger fuel injector in it and I wouldn't go any bigger than a 150cc kit. I know they make them as big as 180cc, but I've also heard they are having trouble with the larger kits. Don't know what those problems are, but I don't really think you need anymore that 150cc for this bike. I'm really happy with the way this one is performing so far.....
Plans are now to go back to that Temple tomorrow with the 14 T sprocket and ride that same hill up and all the way to the top and show the Temple and the view from up there......
Did you see an actual top speed increase once you paired the 15t sprocket with the big bore kit? I'm considering getting a super cub soon, and I'm wondering if the same combo on it would make it at least SLIGHTLY better for highway stretches. Thanks for all the great videos!
Thanks for the comment and a great question. The BBK gave the engine the low end torque it needed to pull hills. Sadly, it did not increase top end even with the 15T sprocket, but it did smooth out the overall power through the gears with the 15T sprocket compared to the stock 14T. What I mean by that is it was less of the high RPM pitch whine when it would top out in a gear. I didn't gain any top end speed with any gearing adjustment with the BBK installed. However, I later installed a Hot Cam and had the ECU re-mapped and that brought out the higher HP this engine needed. To top this off, I had the head ported and with those added to the BBK the bike just sounds like it wants to scream. Before these last additions, it was a struggle to hit the high 90's KPH with it which is still less than 60 MPH. With the cam, porting and ECU work done It easily pulls past those numbers and the highest I've hit is 109 KPH with the bike still pulling strong but I ran out of straight road and I have not desire to go that fast on this bike..... My fuel economy has suffered some with these additions, but not so much that I can't still run well over 200 Kilometers on a tank of gas...... Hope this helps you out......
Great videos, very entertaining and enlightening, keep it up!. Love the Trail 125 in concept and execution, the problem I have with this bike is it retails for $4000+ in the US, all of these improvements you're adding are great and realistically needed, but they cost even more $$$..... bringing the real cost to over $5000 USD. In that price range you can purchase some mighty fine bikes, including the Kawasaki Versys-300x which does everything the Honda can, but twice as good. What should be a cheap affordable little bike, is actually not.
Very true and the dealers bumping up the price with add ons makes it even worse. Not real sure if I lived in the US still that I would have bought this bike. Sad, for the US buyers, but the price here is very affordable and is making it possible for me to do the changes. I just hope that those who buy them in the US can use some of what I've done to mine to make their riding time more enjoyable......
@@danielkazi6361 I don't know where you live Daniel, but in the US, the dealers are price gauging their customers with unnecessary add-ons in some cases over a thousand dollars. Honda is not doing this, but greedy dealers are. I've never questioned the reliability or quality of Honda motorcycles. However, I do question why they produced a bike that is not the best they could have. I respect your opinion, I believe you are wrong, but only time will tell. I can't believe you will leave your bike "all stock" especially if you ride it off road. But that's just my opinion. I hope you have a great day, I know I will......
You have done great with that bike. Are you able to ask your mechanic if it was just a matter of fitting the bigger ejector to get the 142cc kit up and going, or was there ECU modifications required to have it running correctly ? Thanks
Don't really need to do anymore speed test. The bike won't go much over 60MPH and I don't want to stress out the engine as it still is just an itty bitty putt putt bike. Don't get me wrong, I love this bike, it is perfect for what I want to do here in Northern Thailand, but it will not go fast with the set up I have on it. To get more speed, it will need some cam work, some ECU work, some intake work and someone with the knowledge to set it up just right for the speed. I don't possess that knowledge and don't really want my bike to be a hot rod, just needed more low end grunt for the hills... I've got that with the BBK, that was enough for me..... There are some young Thai guys that have souped up some of these engines in other bikes that flat out scream. The mechanic I use, put a turbo on a Honda 125 engine and I swear that thing would do 80 MPH in a block distance... It was awesome, but it's not what I want, so I won't be doing any speed runs..... Sorry, but thanks for the comment.....
I just did a ride yesterday up into the mountains North of my house and this is the first chance I've had to do a fuel economy test on the Big Bore Kit. I'm happy with the results of it. I got 52 KPL for a 153 Kilometer ride in some pretty steep mountain roads. Took a whopping 2.9 liters of gasoline........Not real sure what that converts to on MPG, but it's going to be some really impressing high mileage.......
Hi :) what is the top speed you get with the 14 tooth and the 142cc big bore? Thx a lot , i like to look your video. Just hop honda gonna bring this CT125 to France ☺️
I've not tried a top speed as of yet. Still don't have enough Kilometers on it to go ring it out. When I finally do a top speed, I'll be putting out a video of it. As for the bike coming to Europe, there are some problems with the EU emissions that has slowed up the process from what I have heard. Sounds like it may be a while before you get them there.......
i see all these videos about different tooth sprockets but i dont know what you're expecting to do different. more power? less? no ones really explained it.
I see someone left an explanation on what we are doing. Let me elaborate further on it. We are trying to optimize the power available on the bike to make the type of riding areas that we live in easier to ride. So, if you take the stock gearing which is as follows. A 14T front sprocket and a 39T rear sprocket, that makes your gear ratio which is 359. It is actually .359, but it is always expressed as 359 gear ratio. If you make that ratio lower, you will be able to climb steeper inclines with the same Horsepower from your engine. If you make the ratio higher, you should be able to run faster with your engine. So, when we put a 13T sprocket on the front, it lowers the ratio to a .333 and means that the engine turns the countershaft more times to power the rear sprocket one turn, that gives you more low end which allows you to climb steeper grades. Hope this answers your question......
@@bts650 True. But a front sprocket costs about half what a rear sprocket costs and a smaller front sprocket weighs less. And sometimes if one goes for a really big rear sprocket they'll need to buy a longer chain. Longer chains again weigh more. Also a rear sprocket is a lot more labor intensive.
This kit is made up of stock 125cc parts. Some from Honda, some from Kawasaki. The parts are just being used a little differently from the manufactures intended purpose. The Kawasaki piston is bigger around than the Honda piston, that is how they get the extra cc's. Kawasaki uses the same design of an engine as Honda, only they use less stroke and a bigger diameter piston. Some smart guy over here took the larger Kawasaki piston and put the Kawasaki sleeve in the Honda cylinder and bingo, 142cc instead of 125cc. I've got no vibration from the engine and so far, no engine problems and I've got over 3,000 Kilometers on it in some pretty gnarly riding areas. Now, if you're thinking about the larger 181cc Big Bore Kit, I'd do some serious investigation on it first. I've heard some horror stories here in Thailand how they've blown parts all over the road when they blow up. The young guys around here put the 181cc BBK in for drag racing, so maybe it's just the racing part of it, but I've also been told by a guy in the states who put one on his Monkey and it blew up after a short while.... So be careful what you put in yours, and I'd feel safe with the 142cc kit, mine works great.....
Looks like a good combo for on the road. I like the exhaust, sounds better as well. Does it improve on the performance any? Still waiting on a ct to show up @ my dealers. I have a Super Cub so.... I can’t get a ct right away🥴
The Big Bore kit really helps the power of this bike. It pulls from down low in the RPM's and feels more like a bigger bike now. The 15T sprocket would be a great addition with the BB Kit installed in flat land areas......
After watching your videos I am now reluctant to getting one, unless is a slightly bigger engine. Don't like the idea of it stalling in a moment when I need it to perform the best or get me out of danger .
Good question, I currently don't plan on doing any top speeds on any of the sprockets at this time. However, once the bike is fully broken in, then I may go ahead and set up the GPS speed for it and run a top end test with all three sprockets. Just not any time soon. With the big bore kit and the 15 tooth sprocket, you might be able to get mid to high 60's speed out of it, but that's not really good enough for the US hi ways......
@@TeamDNFracing I had the same thought. I was thinking somewhere just over 100kph with the big bore and 15t. I'm in the US as well on the Gulf Coast, so no mountains, but I'm holding out to see what Yamaha does to replace the wr250r and what the Honda CRF300L will look like here for highway riding. I just can't get over the fun factor on the CT125, though!
same thoughts here, love the fun factor and quirkiness, but for freeway riding isn't the deciding factor based on CC capacity of the bike; if so you might still get a ticket, even if you can hack a few more mph to the factory bike.
Very interesting, I'm seriously considering one of these if they available in the Philippines at some point. My interest in the big bore and the sprocket changes is driven by my weight. I'm around 240lbs, I would only be riding mostly on unmade mountain and local roads and not very often off road. Would a big bore kit compensate for my weight, or do you think a sprocket change would be necessary too?
I honestly believe the big bore kit would be enough, however, the 13 tooth sprocket is not a very expensive item and it really does give the bike some snap with the big bore kit and the 13 both on there. Check out on line shopping sites in Thailand for a big bore kit, they should be able to ship to the Philippines......
I got the sprocket from my mechanic here in Thailand. They are readily available in most bike shops. The big bore kit I purchased from an on line shopping network called Shopee. Here is a link to them: Shopee.co.th and you need to type in CT125 on the search bar at the top of the site.....
This bike will go up the hills a lot better with the Big Bore Kit on it. If you are not to concerned about hi way speeds, I'd just put a 13T countershaft sprocket on it as that will give you pretty good climbing ability......
@@TeamDNFracing we waiting to see if they would sell the ct125 in south Africa. So far we only seen 2 stories about it. Very sad but people here would rather drive then ride. If they ride its a gs1250 or in that engine size. I own a px200 and a p150x. Wonder what the price would be for a ct125. Looks like a really cool bike.
Thanks for sharing. It definitely sounds meatier. :) have you changed the tires yet? When the Trail 125s become more available here, I was hoping to put some Shinko 244s on mine. They have always been a good dual sport tire on my KLR.
@@TeamDNFracing I have used the 244s and the 705s. The 705s are too street oriented for effective use off-road. The 244s have lasted 7500 to 10k miles on my KLR. They are a bit noisy on the road, but perform well. Around steep curves on pavement, I have been able to get the 244s leaned to the breaking point for traction. I am not sure the tire size conversion. I think it would be a 2.5. Shinko has been one of my favorites due to cost. I am not sure what else is available out there. Again, thank you for the videos. They help calming the impatience to finally get one. 😂
I put it back on this morning and did a video on how to do it. Took it for a short run and yep, it's the one that will stay on the bike now. Longer run tomorrow and a video also......
@@andyr4609 Actually shot both videos today, I'm going through all these comments before I hit he editing part. The rides and shooting the video is the easy stuff, it's the hours I spend editing them that sucks......
This kit is made up of stock Japanese designs, a combination of Honda and Kawasaki components. They include a stock Honda cylinder with a Kawasaki designed sleeve, piston and rings. So far I have had no problems with the BBK in my bike. However, both Robert and Daniel have had an engine knock issue with there bikes when put to extreme stress situations. We have also found out that the engine in the Honda Wave (which is identical to the CT) is also having the engine knock with them. The engine knock is more of a pre-ignition knock if you understand anything about combustion engines, you'll know what I'm talking about. It appears the problem is caused by to high of compression in the engine by installing a much larger piston and cylinder sleeve. On my bike, I had the head ported, which put a larger head combustion area and in turn lowers the compression. Roberts bike is in the iTimgarage shop having his head ported, a Hot Cam installed and a ECU from a Honda Monkey installed with a re-mapping of the ECU to improve overall power. These are the same things I've had done to my bike and it literally rips now. Easily will run well above 60MPH and the low end torque is now very usable. Robert is on vacation right now and when he returns in another week we will get his bike and do some serious testing with it. If he has no more problems with the engine knocking, then Daniel will take his bike to iTimgarage and have the same things done to his engine. Reliability wise, I have had no issues with my bike at all and I have over 7,000 Kilometers on my bike since I installed the BBK and I've put it through some very nasty terrain..... Hope this helps and we will be doing a follow up video on the performance of the mods we've done on the bikes.....
We actually have two versions of the kit with a third one using a different exhaust system. The top of the BBK system has the head ported, a hot cam installed and the ECU remapped. That one is using a Murazaki exhaust system built here in Thailand. The bike with the same exhaust system does not have the ported head, cam or ECU remapped. The third BBK has a Moriwaki exhaust system with no cam, ported head or ECU remapped.... All three bikes sound pretty throaty, but the one with the head work, cam and ECU work has that dragster loaping to it during idle. It also rips in a drag race with the other two.....
Mixed feelings on big bore kit. I see how extra torque is helpful, but also wouldn’t want to sacrifice the refinement and durability of Honda engineering. A reasonable overbore (like you did) is probably key- don’t need to over stress the bottom end or have the clutches slip. I bet the 14t and that extra power will work out well with how you use the bike. Still, I wish they put the low range on it. You could run 15 and have extra speed on the road, flick the lever when you get to the trail and have gears equivalent to a 13t.
I did a complete set of test runs with the 13T, 14T & 15T sprockets. The 13T gave it snap and power to climb, but suffered on top end. The 15T made the flat land road rides smooth, yet the engine would not pull 4th gear even on the flat lands and then the entire time on even small hills it just went flat. The stock 14T would pull 4th gear well, but still flats out to soon and suffered on steep inclines to the point it would just stop turning the rear tire. A basic stall out, which is not fun on an off road steep hill as with the automatic clutch, when you chop the throttle, the bike will role backwards down the hill. Sucks when that happens. After I installed the BB Kit, I did the same tests with all three sprockets. Big change in all three. The 13T had loads of snap and power, but still revved out to much on top end. The 15T pulled in all four gears very well and even climbed fairly steep mountain paved roads well in all gears. However, the stock 14T did everything very good and runs great on top in 4th gear and shows really good power in 1st gear on steep inclines. Honda should have just made the bike with a 150cc engine. Problem solved.......
Yeah. I’d hate to buy one, then have that happen. I doubt they will come out with a low range, as changing casting dies would be prohibitively expensive. I suspect the low range on the Trail 70, 90 and 110 was more of a happy accident, that the feature was seen as necessary on the ATC 110 and other 3 wheelers that shared the same power plant. These days Honda seems disinclined fo offer low range. Their top quad the Rincon 680 would be more versatile if so equipped, as would their Ridgeline.
As of looking at your driving and skills. Why not stay stock there is hardly no 110 km/h motorways in thailand and if is there are other roads. My brain never understands how they can drive on wrong side 😆
My bike won't go 110 KPH, but the cars and trucks can and do go that fast and faster, no matter what the speed limit is. If you just putt around at 50 to 60 KPH, you'll get run over. Thailand has the highest per capita ratio of deaths on road ways in the world. You need enough speed to get out of the way of the crazies, and there are a lot of them on the Thai roadways. As for staying stock, you obviously don't own a CT 125 as you would know that it doesn't have the power to maintain forward motion in sand, mud, steep inclines, or loose gravel. There are at least three videos on TH-cam that shows that this bike won't power of any of those mentioned situations. This bike isn't for everyone and there will be those who just love them for nostalgic reasons. I want a small, light weight trail bike that will take me into the mountains of Northern Thailand which means I have to traverse the dangerous highways of Northern Thailand between my home and the mountains. I need low end power in the mountains and still be able to maintain my higher speeds on the highways....... That is why my bike has a big bore kit on it........
@@TeamDNFracing i love the wave/cub/innova series they are really good balanced bikes the Innova make 115 stock. But i think all speeds over 90 is to fast. 😆
@@BigMackhan Phuket is a great place to go visit, flew down there on a trip to Krabi one summer. Very hot down South, but has some very interesting scenic sites for sure. Would be perfect to cruise the area on a scooter or the CT125.........
@@BigMackhan I don't like going any faster than 80 to 90 KPH, that's a nice easy cruising speed as you get older, it's much easier to react to something at a slower speed........
@@TeamDNFracing well I am in the market for a new bike we don't have the hunter here in Pakistan fell in love with the sucker my bad luck, so I am getting Yamaha ybr 125g wish me luck.
@@lalagulutmankhail Sorry you can't get the CT125, you would definitely like it. Good luck with the Yamaha, I've owned several Yamaha bikes over the years, all of them were very good bikes......
I knew before I decided to go for this ride, that I needed to go fill up with gas. This old age shit is really starting to piss me off. I remember when forgetting something just never happened, now it's a daily thing. Hell, I'm lucky if I can remember why I go into the bathroom anymore........
Have no idea, why not to buy a bigger bike ?....😵💫.....and why anyone thinks, they are better than Honda engineers ? CT 125 is build for economic fuel consumption ,but not for hill claiming. Da....
Here is the way I see it mobilgin. You do what you want to do with your bikes and I'll do what I want to do with mine. If it wasn't for a dealer in the US modifying a Honda Cub, there would be no Honda CT today. By the way, I have a bigger bike also....
The road to the temple reminds me of the county roads in east Texas. They're very narrow but almost all of them are paved. Most of the county roads in west Texas are just dirt or gravel, fun to ride my XT250 on but the bike gets very dusty. Your videos were making me want to try a one tooth larger front sprocket on my XT250 but I'm worried about affecting it's hill climbing ability. I just found out this week that Suzuki will be making the DR650 for a least another year so I'm going to trade in my XT for a new DR650 in the next few weeks. I lke the simplicity of the DR, it's air/oil cooled, has a carburetor (no electric fuel pump to go out), it's reliable as a hammer. I bought a new DR650 in 1998 and put almost 30,000 trouble free miles on it before I sold it.
Being from Oklahoma, I've been down in Texas a few times. There are several locations around where I live that resembles much of the USA. The only difference is this is the tropics, no winter weather.......
My daughter and fiancee bought two. I think he plans to do a big bore kit on his. I rode hers but didn't like the shifter, that would be the first thing I would change. Thanks for sharing.
All the small bikes here in Thailand use the toe/heel shifters and I've just gotten used to it by now. I use my toe on both of them, either shifting up with the heel or down with the toe, I've gotten use to it. Makes things a little hairy when I get on my Triumph though........
@@TeamDNFracing I have a heel and toe shifter on my Vulcan 1500 and never use the heel portion. I guess people get used to it but it's not for me.
Great video,
Honda needs to put you on the payroll
your doing a lot of R -n- D for them .
i am looking forward to your next video.
It would be nice to get some kick back from them, but I'm just showing what can be done with this bike to make your riding experience better where you live. If I'd of been in an area that was pretty much flat land, I'd probably leave it stone stock.... Who am I kidding, I' like Tim the Tool Man Taylor. I like more power..........
Really nice sound to the engine....Smooth little power house you have now.....looking forward to the 14 tooth sprocket !!!
Plans are to run as short test on it tomorrow, still another week away from hitting the really tough mountain roads. I just want some time on the engine before hitting it hard.......
Think I agree the 14t is going to be a good fit on there!
Ever since I got this bike, I've said the engine needs more power. Since then, I've been looking at big bore kits and gearing to see what will work best for my riding up here in Northern Thailand. I have to travel some distance to get up to the mountain ranges to visit the places we want to go see, so I still need to be able to run close to 90 KPH up to the mountain areas. Once I'm in the mountain areas, I need the engine to be able to pull from down low in the RPM range and allow me to run at least in 2nd gear up the twisty roads. I really thought the 14 tooth sprocket would be perfect if I could get some usable Torque and another pony out of the engine. I believe we are at that stage now, I'll be finding out in the next couple of days....... Thanks for the comment, glad to see you agree....... Adding to this comment, I put the 14T back on this morning and took it for a short ride. That is the sprocket that will stay on the bike now, it works really good.....
Your bike has a throaty mellow sound now that in my opinion sounds perfect👌. Cool to see your bike pass this small test. Can't wait to see the #14 do its thing.
Probably won't get a chance until tomorrow to do that, I've got business to take care of in Chiang Mai today, so I'll be doing it tomorrow..... I like the sound of the bike also.....
@@TeamDNFracing Something for us to look forward to 📽. Your bike at a side view is starting to look like a Dakar Rally with all the blacked out accessories. Wait until you throw some knobbies on it and that will complete the look... very cool 😎 👌
@@findingneutral Got to do it one SS check at a time. This month is the suspension and next month is the tires. That in my opinion will complete the bike for me. Then Adventure Rides will happen weekly to showcase the bike and Thailands beautiful country.......
@@TeamDNFracing And how sweet will that be. Very in my opinion when you know your done accessorizing and can just kick back, smile, and cruise....😬
Agreed bike sounds great.
it's not until you actually own a ct125 that you really don't know how down they are on power till they see your first hill -and it doesn't have to be much of a hill either. i was pretty impressed how your bike pulled that hill especially when you rode back down as it really showed the grade in more detail.
pretty sure your on a winner there and when you drop to that 14t front-look out warro...lol
all the best eddie!
I've been saying it since I got the bike that it needs more power, not a lot, but a few more cc's and it will be just fine. Ol' Warro won't be able to stay with me on the hi way, but I guarantee, his will climb those hills. It's two different worlds that we ride in. One, he doesn't have the inexpensive access to the accessories like I do here, I'm pretty sure he would put this kit on if it didn't cost him an arm and a leg. For around $30.00 US he did what works for his riding area. It just wouldn't do for me here, I needed to be able to ride 75 to 80 KPH for some distance before I get to the really steep stuff, he only has a couple Kilometers to go and he's in riding heaven. ( I wrote all of this before I realized who made the comment) You've done your bike proud Graham, keep up the good work.......
@@TeamDNFracing your spot on with your thoughts too. if i were your way i'd done exactly the same. why play with sprockets when you can have the whole meal deal...lol
if you can instal the big bore kit yourself or have a handy mate who can its still a very good proposition to do.
@@ridewithwarro I can tell one thing for sure Graham, I couldn't have done this to the bike in the US. The kit alone would have been several hundred dollars and then probably another 2 hundred to get it installed. However, if I were in the US, I'd have my tools and wouldn't have to have someone do it.......
@@TeamDNFracing 'd say here in oz for $200 they wouldn't even roll the bike in to their workshop to start on it so you got a real bargain fit there. plus what they would slug you for the parts alone.....lol
after you do your testing you should offer a service- pack those kits up yourself and slap $50US on them for your trouble putting it togeter and post them out!
after-all you thought of it!
that would help you out a bit accessory wise and more importantly save the potentialk buyer lots of $$$
theres a very big saving in that kit of yours-i think you should think about it
@@ridewithwarro I retired 7 years ago Graham. At that time I swore I'd never have another job, that sounds like a job. Do you want a kit? I'd help you get one, but I don't want to do it for money......
Thanks for the video. I would like you to show us how simple it is to change out the sprocket.
I installed the 14T sprocket this morning and I did a video on how I change them out, because of your comment. Thanks for the comment and I should have done this video a long time ago......
The 15 tooth sprocket also might regain some of the lost fuel efficiency with employing the big bore kit and sure would seem to be the best combination for the highway rides leading to the trail rides. Question being of course does it underperform compared to the 13 or 14 when on tough trails and hills. From your ride today, the 15 tooth handled that temple hill, no problem. All depends I guess what you value the greatest but either way, this is a no lose endeavor. This bike handles and performs great, pure fun. Thanks.
I'm going to be doing some extensive testing with the 14T sprocket on it and if I've got nothing to do some time, I'll go back to the 15T and see just what it will do in the tougher riding areas. I really doubt that I'll ever go back to the 13T now as it just hurts the top speed to much and I don't like revving the little engine up to much.......
Fuel injection sure makes that engine perform smooth. They are just now hitting California and I only see them in red. I want the color you have so I guess I will have to wait. I went to that Shopee website but seems they don't ship to USA. I really can't find the parts I want for my 1982 Honda C70 Passport and Shopee has some really nice goodies. Do you have any suggestions on what I can do?
I'm not sure of all the problems the US market is having getting parts. I know that Shopee is not shipping to the US, but a company called Beez or something like that does ship there. Look in the FB site Honda CT125 Owners group and ask there. That is how some of my subscribers have found parts...... Good luck.....
Do you have a video of you riding with your buddies on the 250s now that you have the big bore kit? Im curious to see if you can keep up now! :)
I haven't gone on a ride with it since I've installed the BB Kit. Most everything so far is just personal ride tests alone. It will probably be another couple weeks before we do another group ride, I should be able to stay a lot closer to them......
@@TeamDNFracing I'm looking forward to it. I love all these videos, Thailand is beautiful and I want to visit there sometime for a break and some culture shock. I've lived in California my whole life but would like to experience something new. Anyways, keep them coming!
@@negachin2334 Then you definitely need to plan a trip to Thailand. When you do visit, go off grid to enjoy the real Thailand and not the tourist places that really aren't what Thailand is all about.......
@@TeamDNFracing That's what I want to do, how would one navigate those areas? Would it require a tour guide?
@@negachin2334 A good GPS and reliable bike and you should be able to navigate around fairly well. It also might be a good idea to speak some Thai......
You have a reserve. There is a vale you have to turn. If you can't find it, go by the cub shop and ask them to show it to you.
No there isn't, this has fuel injection. Bikes with fuel injection don't have a petcock. You are talking about bikes in the last century.
It would great if you could put up a link for a good big bore kit...160 up to 181.,.......
We currently have no plans to put a larger BBK in any of our bikes in the group, so we really haven't even searched for them. I know there are some 162cc & 181cc kits here in Thailand that are made for the Honda Wave 125i, which should fit the Honda CT 125 Gen 1 engines but there currently isn't any for the Gen 2 engined bikes here. As for sending a link, I'd have to do some serious research on them before I'd recommend either of those two kits. I've heard the 162 cc kit is pretty good, but we have not researched them at all. As for the 181cc kits, I've heard they like to go BOOM. Could be because most of the people here who put that kit in their bikes use them in drag races..... We may in the future do another build on a Gen 1 CT125 and when we do, it will probably get the 162cc kit in it, which means I'll be doing some serious research before we settle on a particular kit. As of now, there are a few Japanese companies that sell the BBK's for the Gen 1 CT and you can find the names and web sites for them on the Internet. Use the Honda CT125 in the search bar when looking..... I really can't tell you any more because we haven't spent any time on anything bigger than the 143cc kits we are using....
I enjoy your videos. I would be interested in the top end on pavement as well as torque on the hills. Gas mileage would be great to know. My concern with the bigger cylinder is over heating. I am planning on doing the Transamerican trail. I need to have the torque for Colorado and speed for detours and paved road portions. My ct90 won't do it. I am excited to pickup my ct125 next weekend.
Thinking about doing at least part of the TA as well when i get mine after Feb. I’d like to stay away from highways all together. At least 55mph or less. Mississippi looked awesome.
@@mattp9029 yeah. It looks like a lot of the Eastern trail is on roads. I'm up in Wisconsin and plan on doing a side trail Steve put together from la Crosse to Iowa. I will get a second 125 for my fiance. She has to learn to ride and do trail riding. When do you think you will get out on the trails?
Looks like you guys are going to be having some fun for sure on the Transamerica trail. Top speed is right at 60MPH for this bike stock, don't know as yet with the BB kit in it. Torque on the hills is not quite enough for higher mountain areas, but adequate for normal hills in the stock form. Fuel economy is really good on this bike stock. I got on average of 60 KPL on most of my Adventure rides. Have not had the Big Bore Kit on long enough to do a fuel economy run. Will be doing it next week......
@@TeamDNFracing I can't wait to see more videos. I, too, like the views and trips you take with the bike. I've been to Korea but not Thailand - beautiful country.
@@helowzrd Not sure yet. Likely sometime late spring early summer. The route you describe sounds good too. IdealIy I am looking for a loop...my dealer is saying my bike will arrive in Feb. We'll see...
Have been really enjoying your video clips, thank you! Still waiting for my CT125 here in New Zealand. It's been ordered since August, so I am hoping Santa may deliver to finish 2020 on a happy note. Very best wishes, Mike.
Mike thanks for the comment and here's hoping you get that bike before Christmas.......
I went rhrough all your videos almost in a day. Extremely cool content. I love Thailand as well and would want to tour the country on bikes. When the ct125 gets released in the colorway like yours here in the US will pick up a couple for me and my sons. Quick question, will running your bike almost at prolonged highway speeds with the big bore overheat or damage long term? Planning to do long distance runs. Thanks for the uploads keep it coming!
I'm sure that if you run it for a long time at highway speeds, it will probably overheat. I don't run mine at really high speeds for any length of time, I'm not going on extremely long trips. Just short day trips up into the mountains......
If modding for power if your hope you should see what people are doing to the Grom, which has the same engine. I don't know how much tuning information there is for the CT, but what is available for the Grom will blow your mind.
I'm interested in how balanced the engine is with the bigger bore that and the mileage. Back in my day I had a Triumph Bonneville ... it would vibrate it''s nuts and bolts off if I cruised over 55 mph. My little Honda CL125 twin just purred and did 70 mph .. I never thought about gas .. did over 100 miles of power line roads in Arizona on less than a tank.
Did you say one really needs a bigger bore exhaust with this upgrade?
I don't see a listing from Honda on this kit. Could you tell us what kit you used and there? There seem to be a number of kits that will fit.
Your videos are really a big help.
Good questions: The engine is typical Honda with little or no vibration, even after installing the BB Kit. The fuel economy in stock form is on average 60KPL (Kilometers Per Liter) on all of my Adventure rides so far. Have not done a fuel economy run with the BB Kit yet. If you put the BB Kit on your bike, to get the full benefit of power available, HP & Torque, put a good free flowing air filter like a K&N and a less restrictive exhaust system on it. I have installed an SKA air filter, a Diablo full exhaust system to go with my big bore kit. This BB Kit is not from Honda, it has Genuine Honda parts in it, but is a kit put together by an after market speed shop here in Thailand. They do not ship over seas, someone has already tried. There are many kits that will fit this bike. The Grom, Monkey and Super Cub all have the same top end as the CT125. A hop up kit for one of them would fit the CT125 just fine. Make sure any kit you get has the larger fuel injector in it and I wouldn't go any bigger than a 150cc kit. I know they make them as big as 180cc, but I've also heard they are having trouble with the larger kits. Don't know what those problems are, but I don't really think you need anymore that 150cc for this bike. I'm really happy with the way this one is performing so far.....
I was hoping for a tour of the Temple grounds.
Plans are now to go back to that Temple tomorrow with the 14 T sprocket and ride that same hill up and all the way to the top and show the Temple and the view from up there......
Did you see an actual top speed increase once you paired the 15t sprocket with the big bore kit? I'm considering getting a super cub soon, and I'm wondering if the same combo on it would make it at least SLIGHTLY better for highway stretches. Thanks for all the great videos!
Thanks for the comment and a great question. The BBK gave the engine the low end torque it needed to pull hills. Sadly, it did not increase top end even with the 15T sprocket, but it did smooth out the overall power through the gears with the 15T sprocket compared to the stock 14T. What I mean by that is it was less of the high RPM pitch whine when it would top out in a gear. I didn't gain any top end speed with any gearing adjustment with the BBK installed. However, I later installed a Hot Cam and had the ECU re-mapped and that brought out the higher HP this engine needed. To top this off, I had the head ported and with those added to the BBK the bike just sounds like it wants to scream. Before these last additions, it was a struggle to hit the high 90's KPH with it which is still less than 60 MPH. With the cam, porting and ECU work done It easily pulls past those numbers and the highest I've hit is 109 KPH with the bike still pulling strong but I ran out of straight road and I have not desire to go that fast on this bike..... My fuel economy has suffered some with these additions, but not so much that I can't still run well over 200 Kilometers on a tank of gas...... Hope this helps you out......
Great videos, very entertaining and enlightening, keep it up!. Love the Trail 125 in concept and execution, the problem I have with this bike is it retails for $4000+ in the US, all of these improvements you're adding are great and realistically needed, but they cost even more $$$..... bringing the real cost to over $5000 USD. In that price range you can purchase some mighty fine bikes, including the Kawasaki Versys-300x which does everything the Honda can, but twice as good. What should be a cheap affordable little bike, is actually not.
Very true and the dealers bumping up the price with add ons makes it even worse. Not real sure if I lived in the US still that I would have bought this bike. Sad, for the US buyers, but the price here is very affordable and is making it possible for me to do the changes. I just hope that those who buy them in the US can use some of what I've done to mine to make their riding time more enjoyable......
@@danielkazi6361 I don't know where you live Daniel, but in the US, the dealers are price gauging their customers with unnecessary add-ons in some cases over a thousand dollars. Honda is not doing this, but greedy dealers are. I've never questioned the reliability or quality of Honda motorcycles. However, I do question why they produced a bike that is not the best they could have. I respect your opinion, I believe you are wrong, but only time will tell. I can't believe you will leave your bike "all stock" especially if you ride it off road. But that's just my opinion. I hope you have a great day, I know I will......
You have done great with that bike. Are you able to ask your mechanic if it was just a matter of fitting the bigger ejector to get the 142cc kit up and going, or was there ECU modifications required to have it running correctly ? Thanks
The larger fuel injector seems to have been all that was needed. He did not have to do anything to the ECU........
When are you going to do a speed test after you did all the mods
Don't really need to do anymore speed test. The bike won't go much over 60MPH and I don't want to stress out the engine as it still is just an itty bitty putt putt bike. Don't get me wrong, I love this bike, it is perfect for what I want to do here in Northern Thailand, but it will not go fast with the set up I have on it. To get more speed, it will need some cam work, some ECU work, some intake work and someone with the knowledge to set it up just right for the speed. I don't possess that knowledge and don't really want my bike to be a hot rod, just needed more low end grunt for the hills... I've got that with the BBK, that was enough for me..... There are some young Thai guys that have souped up some of these engines in other bikes that flat out scream. The mechanic I use, put a turbo on a Honda 125 engine and I swear that thing would do 80 MPH in a block distance... It was awesome, but it's not what I want, so I won't be doing any speed runs..... Sorry, but thanks for the comment.....
It may be buried in your replies but what was the hit to the mileage with the big bore kit?
Best guess with the 14?
Thanks, Brian
2021 CT125
I just did a ride yesterday up into the mountains North of my house and this is the first chance I've had to do a fuel economy test on the Big Bore Kit. I'm happy with the results of it. I got 52 KPL for a 153 Kilometer ride in some pretty steep mountain roads. Took a whopping 2.9 liters of gasoline........Not real sure what that converts to on MPG, but it's going to be some really impressing high mileage.......
Hi :) what is the top speed you get with the 14 tooth and the 142cc big bore?
Thx a lot , i like to look your video.
Just hop honda gonna bring this CT125 to France ☺️
I've not tried a top speed as of yet. Still don't have enough Kilometers on it to go ring it out. When I finally do a top speed, I'll be putting out a video of it. As for the bike coming to Europe, there are some problems with the EU emissions that has slowed up the process from what I have heard. Sounds like it may be a while before you get them there.......
Did you get a different injector with the Big bore kit or is that stock?
The big bore kit comes with a larger injector, that is why the bike runs so strong without fiddleing with the system.......
@@TeamDNFracing What injector do you have?
i see all these videos about different tooth sprockets but i dont know what you're expecting to do different. more power? less? no ones really explained it.
A smaller front or larger rear sprocket will reduce the bikes top speed but acceleration and climbing power will improve.
I see someone left an explanation on what we are doing. Let me elaborate further on it. We are trying to optimize the power available on the bike to make the type of riding areas that we live in easier to ride. So, if you take the stock gearing which is as follows. A 14T front sprocket and a 39T rear sprocket, that makes your gear ratio which is 359. It is actually .359, but it is always expressed as 359 gear ratio. If you make that ratio lower, you will be able to climb steeper inclines with the same Horsepower from your engine. If you make the ratio higher, you should be able to run faster with your engine. So, when we put a 13T sprocket on the front, it lowers the ratio to a .333 and means that the engine turns the countershaft more times to power the rear sprocket one turn, that gives you more low end which allows you to climb steeper grades. Hope this answers your question......
@@bts650 True. But a front sprocket costs about half what a rear sprocket costs and a smaller front sprocket weighs less. And sometimes if one goes for a really big rear sprocket they'll need to buy a longer chain. Longer chains again weigh more. Also a rear sprocket is a lot more labor intensive.
Very concerned about vibration after big bore kit installed, what is your take on this?
This kit is made up of stock 125cc parts. Some from Honda, some from Kawasaki. The parts are just being used a little differently from the manufactures intended purpose. The Kawasaki piston is bigger around than the Honda piston, that is how they get the extra cc's. Kawasaki uses the same design of an engine as Honda, only they use less stroke and a bigger diameter piston. Some smart guy over here took the larger Kawasaki piston and put the Kawasaki sleeve in the Honda cylinder and bingo, 142cc instead of 125cc. I've got no vibration from the engine and so far, no engine problems and I've got over 3,000 Kilometers on it in some pretty gnarly riding areas. Now, if you're thinking about the larger 181cc Big Bore Kit, I'd do some serious investigation on it first. I've heard some horror stories here in Thailand how they've blown parts all over the road when they blow up. The young guys around here put the 181cc BBK in for drag racing, so maybe it's just the racing part of it, but I've also been told by a guy in the states who put one on his Monkey and it blew up after a short while.... So be careful what you put in yours, and I'd feel safe with the 142cc kit, mine works great.....
Looks like a good combo for on the road. I like the exhaust, sounds better as well. Does it improve on the performance any? Still waiting on a ct to show up @ my dealers. I have a Super Cub so.... I can’t get a ct right away🥴
The Big Bore kit really helps the power of this bike. It pulls from down low in the RPM's and feels more like a bigger bike now. The 15T sprocket would be a great addition with the BB Kit installed in flat land areas......
Can you provide more tech details on the big bore, and how you acquired it? Is the gas consuption a big difference from the 125 engine?
After watching your videos I am now reluctant to getting one, unless is a slightly bigger engine. Don't like the idea of it stalling in a moment when I need it to perform the best or get me out of danger .
What does your top speed look like with the 15 tooth and big bore kit? Do you think you could use it on highways in the USA?
Good question, I currently don't plan on doing any top speeds on any of the sprockets at this time. However, once the bike is fully broken in, then I may go ahead and set up the GPS speed for it and run a top end test with all three sprockets. Just not any time soon. With the big bore kit and the 15 tooth sprocket, you might be able to get mid to high 60's speed out of it, but that's not really good enough for the US hi ways......
@@TeamDNFracing I had the same thought. I was thinking somewhere just over 100kph with the big bore and 15t. I'm in the US as well on the Gulf Coast, so no mountains, but I'm holding out to see what Yamaha does to replace the wr250r and what the Honda CRF300L will look like here for highway riding. I just can't get over the fun factor on the CT125, though!
same thoughts here, love the fun factor and quirkiness, but for freeway riding isn't the deciding factor based on CC capacity of the bike; if so you might still get a ticket, even if you can hack a few more mph to the factory bike.
Very interesting, I'm seriously considering one of these if they available in the Philippines at some point. My interest in the big bore and the sprocket changes is driven by my weight. I'm around 240lbs, I would only be riding mostly on unmade mountain and local roads and not very often off road. Would a big bore kit compensate for my weight, or do you think a sprocket change would be necessary too?
I honestly believe the big bore kit would be enough, however, the 13 tooth sprocket is not a very expensive item and it really does give the bike some snap with the big bore kit and the 13 both on there. Check out on line shopping sites in Thailand for a big bore kit, they should be able to ship to the Philippines......
@@TeamDNFracing Thanks
Where did u get your big bore kit and sprocket?
I got the sprocket from my mechanic here in Thailand. They are readily available in most bike shops. The big bore kit I purchased from an on line shopping network called Shopee. Here is a link to them: Shopee.co.th and you need to type in CT125 on the search bar at the top of the site.....
Here in Durban south Africa we have many hills. No I don't want a bmw gs1250. As long as I can go up the hill, I'm happy.
This bike will go up the hills a lot better with the Big Bore Kit on it. If you are not to concerned about hi way speeds, I'd just put a 13T countershaft sprocket on it as that will give you pretty good climbing ability......
@@TeamDNFracing we waiting to see if they would sell the ct125 in south Africa. So far we only seen 2 stories about it. Very sad but people here would rather drive then ride. If they ride its a gs1250 or in that engine size. I own a px200 and a p150x. Wonder what the price would be for a ct125. Looks like a really cool bike.
Thanks for sharing. It definitely sounds meatier. :) have you changed the tires yet? When the Trail 125s become more available here, I was hoping to put some Shinko 244s on mine. They have always been a good dual sport tire on my KLR.
Still running the stock tires and will for another month. The Shinko is on my list to check out, don't really know which tire to choose yet.......
@@TeamDNFracing I have used the 244s and the 705s. The 705s are too street oriented for effective use off-road. The 244s have lasted 7500 to 10k miles on my KLR. They are a bit noisy on the road, but perform well. Around steep curves on pavement, I have been able to get the 244s leaned to the breaking point for traction.
I am not sure the tire size conversion. I think it would be a 2.5. Shinko has been one of my favorites due to cost. I am not sure what else is available out there. Again, thank you for the videos. They help calming the impatience to finally get one. 😂
@@TwoWheelWanderer650 I know how that waiting is on a soul. Did my fair share waiting to get mine......
Let us know with the 14 tooth Ed!!
I put it back on this morning and did a video on how to do it. Took it for a short run and yep, it's the one that will stay on the bike now. Longer run tomorrow and a video also......
@@TeamDNFracing awesome!!!
@@andyr4609 Actually shot both videos today, I'm going through all these comments before I hit he editing part. The rides and shooting the video is the easy stuff, it's the hours I spend editing them that sucks......
@@TeamDNFracing I know ain’t easy 😊
I put on a 17 tooth sprocket and an oil cooler
I'll bet it rips down the road with the 180cc and 5 speed then......
@@TeamDNFracing 190cc... over 85mph (got scared to go faster)
@1 1 On the Grom forum for $850 delivered (carburated)
@1 1 My son got them about a year ago, I believe he searched zs190
Is the big bor cit you used reliable ?
This kit is made up of stock Japanese designs, a combination of Honda and Kawasaki components. They include a stock Honda cylinder with a Kawasaki designed sleeve, piston and rings. So far I have had no problems with the BBK in my bike. However, both Robert and Daniel have had an engine knock issue with there bikes when put to extreme stress situations. We have also found out that the engine in the Honda Wave (which is identical to the CT) is also having the engine knock with them. The engine knock is more of a pre-ignition knock if you understand anything about combustion engines, you'll know what I'm talking about. It appears the problem is caused by to high of compression in the engine by installing a much larger piston and cylinder sleeve. On my bike, I had the head ported, which put a larger head combustion area and in turn lowers the compression. Roberts bike is in the iTimgarage shop having his head ported, a Hot Cam installed and a ECU from a Honda Monkey installed with a re-mapping of the ECU to improve overall power. These are the same things I've had done to my bike and it literally rips now. Easily will run well above 60MPH and the low end torque is now very usable. Robert is on vacation right now and when he returns in another week we will get his bike and do some serious testing with it. If he has no more problems with the engine knocking, then Daniel will take his bike to iTimgarage and have the same things done to his engine. Reliability wise, I have had no issues with my bike at all and I have over 7,000 Kilometers on my bike since I installed the BBK and I've put it through some very nasty terrain..... Hope this helps and we will be doing a follow up video on the performance of the mods we've done on the bikes.....
@@TeamDNFracing thank you for all of the amazing info
@@bigboy-no2zo My pleasure, we'll do an update report once we get Roberts bike back from the shop. Should be a good one....
142cc bike sounds throaty compared to reg 124.6cc "125" bike.
We actually have two versions of the kit with a third one using a different exhaust system. The top of the BBK system has the head ported, a hot cam installed and the ECU remapped. That one is using a Murazaki exhaust system built here in Thailand. The bike with the same exhaust system does not have the ported head, cam or ECU remapped. The third BBK has a Moriwaki exhaust system with no cam, ported head or ECU remapped.... All three bikes sound pretty throaty, but the one with the head work, cam and ECU work has that dragster loaping to it during idle. It also rips in a drag race with the other two.....
Mixed feelings on big bore kit. I see how extra torque is helpful, but also wouldn’t want to sacrifice the refinement and durability of Honda engineering. A reasonable overbore (like you did) is probably key- don’t need to over stress the bottom end or have the clutches slip. I bet the 14t and that extra power will work out well with how you use the bike.
Still, I wish they put the low range on it. You could run 15 and have extra speed on the road, flick the lever when you get to the trail and have gears equivalent to a 13t.
I did a complete set of test runs with the 13T, 14T & 15T sprockets. The 13T gave it snap and power to climb, but suffered on top end. The 15T made the flat land road rides smooth, yet the engine would not pull 4th gear even on the flat lands and then the entire time on even small hills it just went flat. The stock 14T would pull 4th gear well, but still flats out to soon and suffered on steep inclines to the point it would just stop turning the rear tire. A basic stall out, which is not fun on an off road steep hill as with the automatic clutch, when you chop the throttle, the bike will role backwards down the hill. Sucks when that happens. After I installed the BB Kit, I did the same tests with all three sprockets. Big change in all three. The 13T had loads of snap and power, but still revved out to much on top end. The 15T pulled in all four gears very well and even climbed fairly steep mountain paved roads well in all gears. However, the stock 14T did everything very good and runs great on top in 4th gear and shows really good power in 1st gear on steep inclines. Honda should have just made the bike with a 150cc engine. Problem solved.......
Nice! Yeah a 150 would have been nice from the factory. I wonder if emissions was the reason, or tax/registration in some markets.
@@JeffinTD Yeah, you never know, they may be putting 150 in this bike next year after all the complaints about no power......
Yeah. I’d hate to buy one, then have that happen. I doubt they will come out with a low range, as changing casting dies would be prohibitively expensive. I suspect the low range on the Trail 70, 90 and 110 was more of a happy accident, that the feature was seen as necessary on the ATC 110 and other 3 wheelers that shared the same power plant.
These days Honda seems disinclined fo offer low range. Their top quad the Rincon 680 would be more versatile if so equipped, as would their Ridgeline.
As of looking at your driving and skills. Why not stay stock there is hardly no 110 km/h motorways in thailand and if is there are other roads. My brain never understands how they can drive on wrong side 😆
My bike won't go 110 KPH, but the cars and trucks can and do go that fast and faster, no matter what the speed limit is. If you just putt around at 50 to 60 KPH, you'll get run over. Thailand has the highest per capita ratio of deaths on road ways in the world. You need enough speed to get out of the way of the crazies, and there are a lot of them on the Thai roadways. As for staying stock, you obviously don't own a CT 125 as you would know that it doesn't have the power to maintain forward motion in sand, mud, steep inclines, or loose gravel. There are at least three videos on TH-cam that shows that this bike won't power of any of those mentioned situations. This bike isn't for everyone and there will be those who just love them for nostalgic reasons. I want a small, light weight trail bike that will take me into the mountains of Northern Thailand which means I have to traverse the dangerous highways of Northern Thailand between my home and the mountains. I need low end power in the mountains and still be able to maintain my higher speeds on the highways....... That is why my bike has a big bore kit on it........
Oh i see i drove alot in Phuket. Well it's a cool bike. 👍
@@TeamDNFracing i love the wave/cub/innova series they are really good balanced bikes the Innova make 115 stock. But i think all speeds over 90 is to fast. 😆
@@BigMackhan Phuket is a great place to go visit, flew down there on a trip to Krabi one summer. Very hot down South, but has some very interesting scenic sites for sure. Would be perfect to cruise the area on a scooter or the CT125.........
@@BigMackhan I don't like going any faster than 80 to 90 KPH, that's a nice easy cruising speed as you get older, it's much easier to react to something at a slower speed........
The first one to like and comment
You even hit that like button before I did and I just got it posted........Thanks for watching ......
@@TeamDNFracing well I am in the market for a new bike we don't have the hunter here in Pakistan fell in love with the sucker my bad luck, so I am getting Yamaha ybr 125g wish me luck.
@@lalagulutmankhail Sorry you can't get the CT125, you would definitely like it. Good luck with the Yamaha, I've owned several Yamaha bikes over the years, all of them were very good bikes......
well, so much for gas gauges! LOL
I knew before I decided to go for this ride, that I needed to go fill up with gas. This old age shit is really starting to piss me off. I remember when forgetting something just never happened, now it's a daily thing. Hell, I'm lucky if I can remember why I go into the bathroom anymore........
Have no idea, why not to buy a bigger bike ?....😵💫.....and why anyone thinks, they are better than Honda engineers ? CT 125 is build for economic fuel consumption ,but not for hill claiming. Da....
Here is the way I see it mobilgin. You do what you want to do with your bikes and I'll do what I want to do with mine. If it wasn't for a dealer in the US modifying a Honda Cub, there would be no Honda CT today. By the way, I have a bigger bike also....
