Stuart, yours are probably the most useful videos on T120 for an average Joe, here, across the pond, real honest reviews and how to video!!!!
A forking good yarn, had me hanging on every word.
Definitely a great upgrade to the Bonneville, my older T100 was transformed.
As you correcting stated, not all riders are the same weight, I’ve upgraded most of my bikes’ suspensions to suit me as a rider, and never once regretted doing it.
Thank you marc and thanks for stopping by!
Done the upgrade very pleased with results thanks Stuart.
cracking one about the coat hanger Stuart 😭😭👍🏻
Thanks Ian and thanks for watching!
Just did this upgrade to my T120 and it’s a noticeable change/improvement!
You make great videos Stuart. I don't even have a Triumph but I love watching them.
Thank you Bob! perhaps you should buy one!!!!
Love the shot of the bike, head-on, with the headers outside the forks, dart screen, all symmetrical and gorgeous. Big thumbs up to progressives up front as a relatively cheap upgrade, given the return in improved handling.
Boom 💥 These puppies are now waiting to be fitted to my Bonnie Black T100 along with my Hagon rear shocks Stuart. Many thanks for your help. Happy smooth riding
🏴🙏🏻🇬🇧
Hello Stuart. I've done the upgrade as mentioned in your video. However I wish I found your channel before I did the job. Very well explained and executed!!
Thank you Iain and thank you for watching sir!
Thanks, I just did this upgrade. Feels like I'm floating, major difference.
Your welcome Ron. Enjoy!
Cheers Stu, just fitted the Hagon Shocks to my T120. Will be doing the front forks in the next couple of weeks.
I just upgraded to these springs and the it made a huge difference.
Another excellent video Stuart. I've been using tecbikeparts for about 5 years now on my 2010 T100 for a variety of parts and more recently on my Tracer 700 for a new exhaust system and they've always been great to deal with and quality parts.
Thats good to know Dave and how do the parts stand the test of time?
Don’t yet own a Triumph, but am researching and hope to get one n the next 12 months. Lovely video, thank you! Subscribed in the U.S!
I’m a new subscriber to your channel. Loving your informative videos and you have a fantastic sense of humour :) I’m looking to get a T120 Bonnie Black. Ive learning so much about living with it with your help. Thanks for sharing my friend.
Looks like I can really do this now...thanks Mate!
CH 01 ....love it. Another brilliant video . Thanks Stuart .😊 👍
Stuart I haven't purchased my new Bonneville T120 yet but when I do your videos certainly put me in the right direction for which mods to do first and then in what order. I did have the opportunity to test ride a T120 two weeks ago. I was very impressed. I'm headed to take another look this week with my adult son. Thanks so much for your dedication to the T120 and the vids you put out.
Your very welcome sir! hope you enjoy you second test ride, make sure you drive a hard bargain! thanks for watching!
Just now getting around to doing this project yesterday 08/02/2018. The fork springs were getting so bad, that triggered me into getting with the upgrade. I must say, one of the best investments in time and money ever! After a 120 mile test run today, I'm amazed at the improvement. Thanks again for video and upgrade info.
Delane, is there an improvement in handling and cornering for you with this upgrade?
Awesome as usual. Now that the weather is starting to cool down, I finally used the grip warmers. They get pretty warm!! I love my T120 and don’t see myself getting another bike anytime soon. This bike is sexy, classic, and a great alternative to the Harley’s. I definitely get a different type of look when rolling around town than the other speedsters do. Love it. This latest upgrade to your bike has me convinced because my wife enjoys being my passenger and I must certainly do feel all the bumps of the road a great deal. Will be looking into it myself.
I'm glad your enjoying the bike sir and I fully agree with you! let me know how you get on with those upgrades!
I know this video is a bit old, but I just picked up my 2023 t120 and thanks to this demonstration I know exactly what I’ll be doing for the first modification.
Dramatic - I’ll buy some! Thanks Stuart
Excellent as usual, Stuart. Thanks!
Thanks Sandy!
Great video great mod Thanks Uncle Stu!
Your very welcome Joe, thanks for watching!
Very informative, well done, also hilarious. Loved it 👍
Thanks for the video , your compasions and instruction is appeciated .
This is great news! TEC makes fantastic stuff, even their video showing the shortcuts for installing their X pipe is just top notch. Thanks for sharing, I'm able to see this bike in my garage within the next year or so and these mods are great information B-)
Thank you sir! I hope you wont be selling the bullet! those two bikes would look great together in your garage. and yes tec do makes some very worthwhile mods and realistic prices!
Oh no, the Enfield is always staying, as is the camping rig, my Tiger. The Bonneville and the Scrambler are always up for an upgrade though ;-)
glad to hear it sir, have always fancied a Royal Enfield myself, I will get one, one day!
Good info and your humor gave me a good laugh. Thanks again.
your welcome Greg, thanks for watching.
Its awesome to know that I will have a video library to refer to when I purchase my T120!
I like your thinking Chris! that is partly my aim hope they come in handy! thanks for watching!
Interesting video. I own a 2011 thruxton and fork legs where identical. Good to know there is a difference.
Yes progressive fork springs are an upgrade that most riders will enjoy.
Great vid Stuart great sense of humour 😂👍
Another great video Stuart. Would be interesting, if you can fit a damper to the other fork, to see what's involved to replace it and if it improves on the suspension upgrade even more.
May well do that in the distant future but I'm happy with her for now. maybe later next year finances permitting!
Once again a really good video Stuart as I said before tec do some really good stuff at good prices as well
I fully agree with you Anthony! and they are a nice bunch of people to deal with too! Thanks for stopping by!
Great vid/coaching
Hi Stuart
I have had the same problem with my t100 ,now I know why!
Only one cartridge, tight B××××××s and as you said a premium bike .
Had a look at Ted parts and springs on the way.
Please keep up the good work and I will up grade the rear shocks to the ones on your t120.
Also been biking four over 36 years may it continue .
All the best .
paul
Hi Paul the spring kit for the T100 is listed as a separate kit I think so you may find its a different set up. let me know, I would be interested to find out!
Very helpful video! Currently in the middle of making this upgrade to my 2022 Street Scrambler and was a bit alarmed to find no dampener rod on the left fork - lots of head scratching whether this was a manufacturer error or intentional. Glad to see it is normal but also not impressed by Triumph creating this imbalance, cheers!
That special front fork tool, brilliant! :-)
Yes! i have the same springs in my T120. They are indeed a worthwhile upgrade! I wish i had this video for reference back when i installed them. it was quite a painful affair of trial and error. (as my poor deformed aluminium caps can testify ) Kudos for making this video. i'm a big fan :)
I Know what you mean I ended up having to use those instruction things! thank you sir and thanks for watching!
Just fitted these thanks again 👊🏻
Do you still have the British custom end billets fitted to you t120?
Great video. You are a special tool!
@6:30 love the story of that tool, the Coat Hanger 01, that's typical nonsense British humour and I really love it, sincerely you made my day with this. Big fan of the Monty Python here. Cheers from Belgium.
Hi Stuart
Thanks for your reply , will let you know along with the K&N air filter.
At the moment paying out on a Restoration ,my 1977 Honda cb 400/4 .
Its all money .
Regards .
Paul
sounds interesting! good luck with it!
I wouldn't have disposed of the pizza slice so nonchalantly. A very good upgrade though Stuart and explained in a way that even I could understand. :)
dont worry i retrieved it after filming!
Another great video, and very funny.
CH01 top stuff 🤣 I fitted these springs to my 2011 SE a vast improvement, 👍🏻
Like the spring remover 😉..... just wondered wether spring and rear upgrade on my speed twin would , the jarring from the suspension especially the rear is unbelievably harsh.... I thought my shoulders and head had left my body .... another great vid Stuart ..... thanks
Things are getting better and better. :)) The plausible deniability made me chuckle. :))
Thank you sir! and thanks for watching!
Just a little tip put some tape round the nut to prevent the socket marking the soft aluminium 👌🏻
Cafe Racer hey mr racer thanks for that i did try that initially but the socket cut straight through it which is why i siggested a piece of cloth. It might just have been that my socket was a little tight. So it may still work for others!
The 6:30 mark instructions are gold!
Great job Mr. Stuart...!
thank you sir!
I will definitely be ordering one for my T-120, it needs some help!
yes they all do! good choice sir!
Great video
Thankyou Stuart for your entertaining and informative vid.
I'm just waiting for mine to arrive. Great vid though👍
My speed triple was the same and I changed springs to ktec and shock to wilbrers with hydraulic pre load adjuster it's what I wanted as like you said its budget for the masses but not for me 🤔🍀👍
Hey Stuart, superb video as usual and I loved the narrative. Attempting the CH01 tool removal from my wife's arsenal would be suicidal - she knows when I've changed two tins beans in the kitchen. Fortunately I have some ex-MOD ones (serial no. MOD-CH01-Plastic-1 of) that will do the job. This will now be the first mod' on my T120 as we've discussed the front end performance on several occasions. Thankyou again sir - you are my go-to T120 library now! Oh and my waxoil arrived from Amazon at last so the bike will be getting a winter Fillingham this afternoon.
LOL shame you were not in the army Paul you could have got some tuition from the commandos re obtaining a CH 01. let me know how you get on with it, and you know where I am if you get stuck! re the wax oil remember to warm it up in a bucket of water, and a few additional aerosol nozzles might come in handy in this cooler weather. any will fit!
Cheers Stuart - will let you know how it goes but I have prepped as per your video so hopefully should be fine.
good luck with it!
Very clever, funny and informative 👍
thanks phil and thanks for watching!
I've just ordered pair of springs for my Street Scrambler so hoping they improve the disappointing standard setup. These forks are pretty basic and very easy to work on compared to a pair of high end, upside down forks on a Superbike. The SS is a lovely bike to ride and deserves better suspension.
Just did mine on my 2020 T120 Diamond this afternoon and thanks to this video and a couple others it made this job a breeze. That said a couple things I have noticed. First is to loosen the top yoke pinch bolts (6mm) as I think it makes loosening fork caps easier. Mine came loose nicely. I don't know if I see that called out at all or enough. There is another video with a Speed Twin where the guy gave up because he couldn't loosen the cape, but never let off the pinch bolts. Perhaps not necessary but just a thought. Secondly, when disassembling the right side (damper rod side) I did not find a shim/washer between the spring and spacer. All other videos I see seem to have one. I have to check the parts diagrams but I reassembled without it. Mfg assembly oversight? Model year change? Not sure. Lastly, FWIW, a reasonable length of the correct I.D. clear vinyl tubing slid over the damper rod threads works as a nice extension that makes working over and retrieving the rod from the depths of the fork leg a painless process. This one wasn't bad but my previous BMW was mush fussier.
Great video,
Nice of you to say so Martin!
Ha Ha nice video, I ordered new tyres (to be fitted tomorrow 1400) due to some scary twitching on the front on sharp right turns if dropping in quickly, Front tyre down to 2mm so needed it anyway. I also ordered Hagon rear shocks Monday as the build to my weight and tired of them bottoming out two up. but now I think I should maybe get the springs with the oil kit from them to. I didn't know about the cheapskate trick of only one cartridge in the r/h fork, seem like a engineer would not do that unless its a money saving exercise. Thanks for the video.
Just puts me of Triumph totally
Thanks for outlining the process Stuart, very much appreciated!!! I will be doing this upgrade this month so this is going to come in so handy. I'm also going with the TEC Progressive fork spring kit (exactly the same), great suggestion. The kit is about $79 USD here in the states.
Hey up Mr Rider! I concur with your decision sir, I think these offer the best value no nonsense upgrade on the market at the moment! let me know how you get on!
Totally agree, will do mate.
What an amazing review presented so nicely that even an amateur like me was sufficiently informed and made aware of the fact that even an automobile needs to be cared for a lot to derive good value for money. Thanks again.
You should sell that special tool technology, Stuart. I'm sure the other half won't notice if all her hangers suddenly disappear!!!
Always great videos! Keep’em coming 👍. Just hope you don’t go broke in the process. LOL!
😂 instructions in a safe place 👍🏻. So funny.
Thankyou Dervman and thanks for watching!
Great vid cheers
our very welcome sir, thanks for watching!
Thanks for that great video, love also the jokes here and there.
I have a 2020 street twin and wondering if Triumph went for that asymmetrical left/right set up too. Any idea?
Useful, interesting and funny.
Just carried out this upgrade. Very informative clip. Thank you. Shame Triumph charge a premium for a bike that needs both ends of the shocks sorting, great bike but come on - how much would better shocks cost the OEM
Fully agree with you Keir. ridiculous penny pinching! thanks for watching!
Well.
She noticed the clothes hanger.
LoL.
Great video.
one damper ONLY!? My god, the surprises with this bike are endless. I refrain to make more comments but .... shame shame shame!
Nice video bud ! Coat hanger wife won't notice PMSL superb ! ;-)
Thanks Paul and thanks for watching mate!
Once again, I learnt something and will do immediately, probably this week:)...THANK YOU. A quick question: should I go for the whole set ( +load adjusters) or the fork springs alone would be sufficient? Best
I might have to go get to business supplying those CH-01 tools for $45 for folks who aren’t comfortable fashioning one for themselves.
You Shark! you don't secretly work for Triumph by any chance do you?
Stewart to get the oil out of the front forks you could always go to a remote control airplane fuel line hose and stick it down in the tube long enough to go to the bottom of the tube and suck it out with a large syringe
Great video Stuart, mate what are your thoughts on maybe purchasing another dampening rod and new fork cap for the other side of the forks whilst i'm doing this job?
Nice video, thanks for sharing. I am not sure if it matter which sides of the springs points up (force = reaction).
As far as performance is concerned no, but, it will affect damping fluid displacement so tighter coils should go to the top.
Great video! As always helpful! I'm looking some of these TEC parts for my Street Twin. I wonder which are your impressions after some months of use.
jordi tobeña que tal van esos muelles? Mejora la Street? Saludos!
Really well laid out instructions. I have just successfully installed the aforementioned springs to my T120 so we’ll see what difference they make.
One question, does anyone have the torque settings for the fork caps?
22 Nm
Very well articulated.... Thanks.
I own a T120 and was wondering if this would increase the ground clearance and give me a taller seat! I understand the rear suspension also would need attention. Requesting for your advise, to get a taller seating and ground clearance.
This as I get cramps on long rides.
I'm from Bangalore, India.
Also... Regards the damper tube holding tool. Look in the garden shed, or a quick visit to Poundland and get some of that green plastic coated wire used for holding up plants etc (In case it's not immediately obvious I know nothing of gardening). Snip off about three foot of the wire (They even have their own handy snipper). Strip about four inches of the plastic coating with your thumbnail (Yes, you will damage your thumbnail), wind the exposed wire a few times around the threads on the damper rod and twist to secure. Leave the other end hanging out of the top of the fork. Obviously you will need to slide the various spacers and springs over the wire but it does make pulling the damper rod up much easier. Dispose of the used bit of wire responsibly. Check with your local council if it should go in recycling or general waste. Should only take about an hour or two waiting on the phone.
Find job. Thank you Sir...Sal : )
lovely
Brilliant use of the CH-01, sir! With the damper-rod fork on my older ('02) T100, I opted for Race-Tech Cartridge Emulators and springs; do the work yourself and it's not that expensive, utterly transforms the front-end feel (stock suspension was far too soft for my 190 pounds). Some time back I purchased a Pit Bull stand for the front (as I recall, originally for the purpose of installing Race-Tech products in my Daytona's fork); I highly recommend one for the occasions when you simply must remove the fork legs, or even for wheel removal. Takes only a few seconds to stably prop up the front with no wobble.
Hi Stuart...love your videos; they are VERY well done. I have a set of TEC front fork springs that I'm getting ready to install. One question...For the required tools, are you saying 40 mm spanner or 14 mm spanner? I'm assuming that you mean 14 mm. Thank you, sir.
Great video and the tip on the fork oil weight is really helpful. I was wondering where the fork drain nut was, now I know, there isn't one :-( I have been contemplating upgrading the rear shocks, but the front end seems in need of more attention so I will be undertaking a fork spring upgrade over the winter. Do you plan on reviewing fork braces or do you think they are unnecessary?
Hi Wayne, not entirely sure about fork braces, yes I do think they will assist with handling, I may review some in the future but I have no immediate plans. It all depends on who starts to offer them for sale and the nature of their design. good look with the springs!
Very inrteresting and informative Stuart. I can't believe the single damping rod how much must that save Triumph? I bought one of the early Trophies in 1991 but I would think long and hard about anot one.
Yes its a cheap assed trick Peter! then they have the cheek to charge £10300 for it!
Stuart I can actualy sell the Ch tool for £9.99 plus £2.50 postage . Nice video thanks
as long as you send me my cut Paul thats fine!
I fitted progressive springs to my old T100, made a big difference.
But one damper rod for both legs? I've re-built many a set of forks, some early ones with no dampers, some with shuttle valves, but I've never encountered that before, it doesn't make engineering sense. I wonder if another one can be fitted to the other fork leg? (with the correct top nut of course), good vid anyway, cheers, Dave
Hi Dave I fully agree. the top nuts are the same so fitting a new one wouldn't be a problem and yes Triumph do apparently sell replacement cartridges! suitable for the left leg! thanks for watching sir!
Very good video Stuart and it looks relatively simple to do the job. I wonder if Triumph are taking note of this and the comments, because in selling a bike, for this much money, which is, after all the flagship of Triumph, with its history and heritage, they may well lose their customer base because the cost cutting meanness says that they designed the bike for looks and not comfort. I will do this upgrade, but if I am still not satisfied with the ride, given that I do have a herniated disc in my neck and need the road ironed out, I will sell it to someone who doesn't have that physical problem. A shame because she is a stunner. P.s. I have found that riding it in rain mode is a much better option, particularly around town, but I will use it all the time.
let me know how you get on !
Why did you not go with Hagon fork springs as you used them for the rear shock absorbers?
themassofmen because they require the oil to be changed.
Got the tec springs today. The plastic spacers lack sophistication. I'm sure they will help the front end, but may still upgrade further the rear from the 2810s, either a 20 spring upgrade or ask to have an exchange for the nitros. The bike's weight needs a rear that is man enough for it as my lower back feels a bit like I've ridden a horse for the first time at the moment.
How can a spacer lack sophistication? I don't understand, why does it need to be sophisticated, its a spacer!
Hello Stuart. Have you tried TEC rear shocks? I know you have Hagon installed. Just asking out of curiosity. May be you can ask TEC to lend you one for comparison with Hagon and OEM shocks. As this video is sort of a good marketing of TEC parts, a future video on comparison between TEC vs OEM vs HAGON will give viewers a broad range of insight from an ardent motorcycle enthusiast.
Hi Rohit, last time i checked they didn't have any available for the T120.
Thanks Stuart and very timely as I just orderd the TEC suspension upgrade front and back (to Oz). I had read about the damper rod and wondered if anyone just got rid of it altogether? Also has anyone reading this set their TEC back shocks to hheight. If so, did it avdersely affect handling?
Hi Huey, apparently Triumph do sell a damping cartridge for the left leg! I wonder why!?but I haven't heard of anyone removing it as I would imagine it would just make matters worse. ill leave others to comment on the question of height adjustment as I have Hagon nitros fitted which cant be adjusted for height. thanks for watching.
Very interesting upgrade - Is it possible to retro fit a second damping unit in the other leg ?
I see you use the more modern fork spring removal tool.... I had only the older multi use type. I managed to just unwind the tool for use as the all important spring removal option and when finished, I managed to rewind it up and replace the tool into the wife's wardrobe. I'm sorry to say though, returning this tool to the wardrobe was not actually as stealthily accomplished as I hoped. Seems that just one day later someone noticed an oily smell and a ruined, oil stained blouse.... oops.
Suan Pailom Coffee Roasting ah yes the older version did have its drawbacks!
Iam still laughing histerically about the comment about replacing the hanger to your wifes closet. Golden material.
LOL glad you enjoyed it Gary! thanks for watching!
ALSO TRY "OLINS OIL " BETTER OIL ! ALSO "NOLOGY " COILS AND SPARK PLUG WIRES, AND SPARK PLUGS ,I DROPPED THREE THEETH ON REAR SPROCKET, MAKES MORE LOW END POWER
Finally, after three years of searching, I found a distributor that sells the Special Fork Kit CH01. Unfortunately, after I paid the exorbitant shipping cost, they sent the CH02 kit. Useless! In a fit of anger I hoisted up the entire bike, flipped it over, and shook it like a mad man until the springs dropped out (pouring flammable fluids all over the garage floor). Trying to calm down I blazed up a joint and thoughtlessly tossed the smoldering match on the floor which, predictably, caused the entire garage to burst into flames. Upon fleeing, and with no small irony, the only thing I grabbed were the old fork springs. To be honest, I now wonder if the whole thing was worth it . . .
Really interesting and useful video. Thank you. Just wondering if Triumph have improved the fork spring recently, as my new T120 (2 week's old) feels pretty good on the front end. I'm a heavy rider (18.5 St) and so far so good. But if it's the same as previous versions, I suspect it will soften a lot after a couple of thousand miles and may then need upgrading to progressive fork springs. Any thoughts on this?
I’m thinking off doing this.The suspension on my Street Twin isn’t very good.
Which panniers do you have on the bike in this video? They look to be of very nice quality.
Does this spring kit work on the T100 as well?
