Awesome thank you for the reply, my local dealer has one of each the sx and xc so i was gonna get the sx to save money but i mostly ride the steep and slow stuff so I wanted to make sure the sx would work for that. What gearing would you recommend? And can I use the stock battery or do I need to change that out as well?
Great video, appreciate all the content. I have a 23 300sx. Going to try doing a couple hare-scrambles this season. Open b, Michigan. Races are a about 2-1/2 to almost 3 hours depending how the leader finishes. My main question. Do I get an xc tank, or can I make it the hour and half before fueling ? Thanks in advance.
@@WitnessTheSickness99 I did a spring conversion on the forks, and used an 18" rear. Other than that all stock. I have been able to make it 1/2 way before refueling on the stock tank.
@@trevorcarr7716 thanks for the reply. I’m looking to use a 300 Sx for hare scrambles in the UK as we can’t get the XC’s here. Do you have any issues with the 5 speed gear box or is it ok for you?
So far it's been good. I did go up a tooth on the rear sprocket ( 14-50 now ). The fastest I've clocked in at a local race was just over 61mph. For my local harescrambles, that's been plenty fast enough for me.
Thanks, Morgan! I’ve been riding a YZ 250 you helped me with some questions when I rebuild it last , it’s been running great, thanks for that, this year, I think I’m going to upgrade to a 300 two-stroke , so far I’ve had my eye on the 2023 husky TX300 , i’m a woods rider , Which KTM is closest to the TX ? I like the explosive power of the YZ. However, would be nice to have fuel injection in electric start 😂
The air fork can work for any weight, just depends on what kind of terrain and what you’re looking for. They are the best at Moto and high speed stuff. The spring forks do better at the Rocky chunky stuff
I get so much awesome KTM info form you bro! Thanks for all the work that goes into the videos! And I'll probably trade my 21' 350SXF for the 300sx based on how it does in trails!
Cant decide between an xc or sx. I ride mostly trails but like to hop on a track every now and then. Ive only ever had motocross bikes so some feedback would be great.
I bet the shafts are the same actually. Just different drums and shift stars. And spacers to take the place of gears. I will try to remember to check the parts fiche
Can a headlight, brake light and turning indicators be added to the 300 XC? I'm planning on moving to AZ and that's all they require for a plate. Thanks! Matt
I am still currently split. I rarely use 1st on my 18 xc though it has saved me botching a hill a few times and gets used mostly sweeping peewee races.
Is your skid plate factory or after-market? Additionally, are you saying that it looks like a 300XC skid plate would fit on a 300SX because the mounting holes are the same? I'm picking up my 300SX tomorrow and would like to order a skid plate.
Curious on what you think about the 5 speed in really tight trails, steep climbs, and high speed straights. Range with the SX tank? Stock suspension valving thoughts? Oh... and your channel is soooo freaking awesome! Thanks for doing what you do!
5 speed will be good in tight stuff (always in right gear) but would be less than optimal in high speed stuff. SX tank is probably only good for 35-40 Miles depending on where and how you ride. Suspension is going to feel really good at speed even in the Rocky stuff as long as it’s 2/3rd gear stuff.
Me too. I really have no need to go more than 50 - 60 mph on my trails. I'm interested to hear if you think gearing down with a sprocket change would make 1st low enough for tight trails. Thanks for doing this!
Oh... and does the additional air filter cover with more holes actually make a difference? I agree with your comment... my default would be not to use it to help keep the air filter clean.
Also curious how much you can soften up the stock suspension for the trail. I know it's a moto bike so will still be very stiff, but just wondering between the SX and XC. I'm 205lbs without apparel.
Hey Morgan, PLEASE help if you can. I picked up a 23 300sx, I always go SX and add an XC tank. KTM or anyone else cannot confirm if I can buy the XC tank only and use the SX pump. They use different fuel pumps but it may just be for the fuel indication. If the pumps are otherwise the same, and the place where the fuel is drawn is the same I should be good to go. Can you confirm? Also, thanks for all the videos, nice to ge the heads up before I start riding it.
I will try to check. I strongly think that you’d be fine with the SX pump. Of course, having two pumps wouldn’t be terrible. One with each tank so you can swap tanks quickly. I will probably get a second pump when I get another tank.
@@highlandcyclesCool. If the power delivery is similar to the XC I may very well go SX. I looked at the gearing and the SX has the same first gear ratio as the pre '23 XC and 2nd gear is even a little lower.
I have a question i just rode my 2023 250 sx and i had a few backfire when i shut the bike off when we stopped it happen twice. Also on our second ride of the day after a 15 mile ride we stopped for a few minutes. Went to leave the bike would not start. I Didn't use the cold start. The motor was warm It took 8 times and a little gas to start . Did this happen to anyone else?
Holy shit I did not realize the price difference was that much that's crazy. A skid plate and kickstand don't cost $2k. The xc 4 strokes only cost $400 more.
Talking to the owner of this bike, we think that it’s KTM’s way of trying to compete with the YZ market in money. The 250 and 300sx aren’t WAY more than the YZ250
I'll bet you could add a 6th gear for under $300. That was the case with my 2017 FC450. The Fx 6th would drop right in. 6th is blocked off with a spacer in the FC.
@@highlandcycles Need to convince your buddy with the SX to pay you to put in a 6th gear. Then you would have an excuse to figure out how to do it. I bet you would get a lot of views on that one. Especially since no one else is likely to do it any time soon.
A huge reason for owning a KTM is a 6-speed transmission. I suppose it's for weight savings but I don't know why they wouldn't just put a 6-speed transmission in the SX it's not like it would hurt anything
It isn't a w transmission but it is closer to one than they used to be. 1st is low and then they are evenly spaced. Further apart than the sx but closer than the W
With all the great changes KTM did to the 2023's, why did they decide to use such a cheesy radiator cap? Hopefully All Balls or Tusk will make a better replacement.
If they make a 52 gear sprocket it would give a 3.71 with 14 front. Would that be a good way to bring the SX ( 3.5) gearing in line with he XC ? The XC gearing with the cool 6 speed is hard to beat. One other thing ... XC a trail bike but they put a front suspension so hard for the trails that " it's hard no matter what you do " ?
I just picked up the 2023 sx
Can't wait to take it out this weekend
This has become my favourite dirt bike channel on TH-cam, great work Morgan! 👏👏10/10
Wow, thanks!
Thanks to your channel i kinda know what to what im getting my self into😁
Please let us know if the gas tanks are interchangeable between the sx and xc.
Can you put a fan kit on the sx?
Yeah, the stator is the same as the XC as far as I know. But you need to use the Tusk one that draws half of what the TrailTech does.

Will that xc tank fit the SX?
Yes
Im thinking about buying the 23 250 sx i like the fastway kickstand. Im glad i watched this video.
The thing that prevented me from getting a 250 sx back in 2021 was a lack of electric start. That’s why I got an xc.
Not an issue now

@@WitnessTheSickness99 I did a spring conversion on the forks, and used an 18" rear. Other than that all stock. I have been able to make it 1/2 way before refueling on the stock tank.

Enduro Engineering.
I thought the sx was air forks and xc was springs?
Are they both pre mixed?
Both pre mix, both air for 23
Thanks, Morgan!
I’ve been riding a YZ 250 you helped me with some questions when I rebuild it last , it’s been running great, thanks for that, this year, I think I’m going to upgrade to a 300 two-stroke , so far I’ve had my eye on the 2023 husky TX300 , i’m a woods rider ,

Hi Morgan, tell us more about the clicker settings
Will do
How many teeth are you using on the 300 XC rear sprocket? I was thinking about switching to 51.. would that help on trails like 5 MOH?
50. Yeah, 51 would be good for the harder stuff
Thanks for the videos again mate ! Keep going please. I am waiting for my 300sx because the 300XC in Australia is sold out.😬
Question can the air forks work well for a 230lb rider by just increasing the pressure or do I need to do spring inserts?
Thank you in advance
The air fork can work for any weight, just depends on what kind of terrain and what you’re looking for. They are the best at Moto and high speed stuff. The spring forks do better at the Rocky chunky stuff
What shift lever is that and is it bigger?
It’s longer and it’s a hammerhead
@@highlandcycles everything I look up for my 300sx says, “does not fit your bike” annoying
@@oldheadneverlacking7010 I didn't buy this lever. The owner of the bike did. I am sure it is one from a 22 SX.
@@highlandcycles good deal, that’s the answer I was looking for. Thanks sir. Merry Christmas and happy new year
When should I fly out for testing?
Now, We are doing it this weekend
Awesome, excited to hear how the first ride on SX goes..
Are the cranks the same?
Don’t know yet.
As always bro. Good stuff (from the sweatbox of central fl) 🤘🏽
Any difference in flywheel weight?
Not sure yet!
I get so much awesome KTM info form you bro! Thanks for all the work that goes into the videos! And I'll probably trade my 21' 350SXF for the 300sx based on how it does in trails!

Not yet. Impatiently waiting

Get the XC. It does both very well.
It would be interesting to know if the shafts are the same. Might be nice to be able to mix and match ratios.
Aren't the XC and XCW 6 speed, not 5 🤔.
I highly doubt they'd work. SX wider physically I'm assuming.
I bet the shafts are the same actually. Just different drums and shift stars. And spacers to take the place of gears. I will try to remember to check the parts fiche
@@highlandcycles I tried to find out if the shafts were the same, but I couldn't find a fiche for the sx tranny with the little looking I did.
Did u say wifi module? Are they planing on making it like the YZ450s
Yes. That is the idea.
Can a headlight, brake light and turning indicators be added to the 300 XC? I'm planning on moving to AZ and that's all they require for a plate. Thanks! Matt
is the sx a 5spd?
Yes
Witch one will make a better snow bike?
Probably the SX
I bought a 24xc to put a timbersled on. What makes the sx a better option for that?
Love my '17 SX 150 but wish it had another gear or 3.
???? What is top speed on the SX ????? And 250sx
Thanks
Based on my XC I’m guessing top speed is maybe 60 wound out
I am still currently split. I rarely use 1st on my 18 xc though it has saved me botching a hill a few times and gets used mostly sweeping peewee races.
It’s a tough choice honestly.

Mine is the enduro engineering rubber mounted plate with the link skid. And yes the XC plate will bolt right up
Please try backing off clickers to see if you can get stock sx acceptable offroad
I will for sure.
I have the oem ktm WiFi module. It plugs in and lights up but the 300sx isn’t in their system yet. Maybe eventually
Dang. Where did you get that.
I got it at my husqvarna/gasgas dealer. I’ve had it on my 21 ex350 and my 22 mc450. I mapped them through the husky app. Never had any issues.
@@zackeryconner2594 man, no one around here can get them. I’ll dig deeper

So much ktm content. Puke lol

It’s super adjustable honestly. In stock form it will never be crazy plush but it’s really not terrible
@@highlandcycles Cool. Thanks. Looking forward to your ride video.
My 2021 xc has a thermostat. Does the 2023 xc and sx have one ?
No. Neither have a thermostat
You or someone said you can’t swap tanks on the sx with the xc because the sx fuel pump won’t work in the xc tank. Not sure if that’s true or not.
I didn’t say it. I am going to figure out if that’s true
Anything yet?
@@Brandon-dd8dw yes it works I have an sx pump in the xc tank on my 300sx
These new bikes are freaking rad!!! I’m gonna have to ride my old 2012 into the ground! LOL!!
So you’re saying the sx gearbox and gear ratios are better?
If so, better how? (Or if I mixed that up, same question haha)
Not better. Just closer together. Some people like that.
Oh boy cannot wait for the drama, and if you like it more than the xc, and if it is perfect.
Hahahahah. I think it’s going to very similar to the XC
O-ring/X-ring chain?
No, forgot to mention that. It is a normal moto chain.

Seem to be identical that way.

What should we expect with the upcoming WiFi module?
I am expecting some access to mapping and code reading. Hoping for code clearing
Holy shit I did not realize the price difference was that much that's crazy. A skid plate and kickstand don't cost $2k. The xc 4 strokes only cost $400 more.
5 speed vs 6 speed as well. Still doesn't justify $2k imo.

Will still get the XC in the new year👍
I like the XC for all around.
@@highlandcycles You certainly know how to spend my money Morgan lol👍
Just grabbed the SX. What you guys running for oil in transmission? You guys motorex or die?
I've always bent up Excel wheels far easier than the D.I.Ds. Excels are a lot lighter though so that's the tradeoff.
I did some looking and I think the stock ones are not DID. They are some off brand thing. Still pretty good as long as you keep the spokes tight.

Flywheel?
My 2014 SX has a different cylinder head than the XC/XCW, also the CDI Is different.
According to parts numbers the XC and SX use the same pipe. Atleast according to the parts numbers listed on the KTM site.
Thanks man.
You really make me want a fuel injected two stroke. I’ve stayed away because I don’t want anything carbureted in my life.

My 2014 125SX is a 6 speed trans.
So the xc has a shorter 1st gear and second gear then a taller 3rd gear -5th gear so.its a wide ratio and the sx has more of a race/track bike
It isn't a w transmission but it is closer to one than they used to be. 1st is low and then they are evenly spaced. Further apart than the sx but closer than the W

Agree. It does feel solid to be honest. Just a pain to get off
Whats up
Yo
XC rims are made by giant
Thanks
Really not the same bike at all out on the trail. The money it would cost you to get the sx close to an xc would make up the price difference
Depends on the trails you ride. Just took them both out and the SX isn't bad at all on our trails
Change the piston it is junk
So far mine is ok. We will see though.
