I did this to my 2024 250xcw as well as the more aggressive throttle cam and oh my gosh I’m so glad I did! So good! Second and third gear ARE much more usable and I’m not clutching so much in first gear in the tighter trails!

A couple years back I switched to a 12-52 setup on my 250 xcf, and I don't see any downside to it. Makes it basically impossible to stall whenever I have to crawl in a rock garden or riverbed or bunches of downed trees. Ya on single track I need to shift up to 3rd or 4th, but thats why these bikes have 6 gears. Plus it's super fun letting the bike idle in 1st gear and only be moving 1-2 mph

Be sure to check the chain slack spec. The new chassis has a significantly higher slack specification.

Just a heads up, I had a Primary Drive front sprocket on a yz450 that ended up stripped my countershaft requiring an entire engine teardown. Assume it was a slight tolerance miss-match with the aftermarket part. Expensive lesson learned on that one. From now on (at least with the front sprocket) OEM only for me.

hi fellas, yesterday I tried 12/48 for the 250 TBI. Works pretty good in slow speed technical stuff.

I'll be honest, I've never noticed much change in handling characteristics when moving up or down a tooth or two here and there. It's not moving the axle enough, maybe a 1/4 inch. You're not drastically altering the wheelbase. As for the rear suspension, just reset your sag and loosen compression by a click if needed.

Here waiting for September 1st to buy bike parts with Kyle’s link to Rocky Mountain 😏

I would like to hear about the handling characteristics and shock performance. Nimble equals less stability and harsher ride? My guess is there is no difference you can feel.

Duh! Why did I never think of using my calipers to check the adjustment side-to-side!

If you’re worried about reducing the wheelbase just use a longer chain.

You got me wanting to start experimenting with my wheel base now.

love it dude hope we meet sometime

Hey Kyle. I ran a 12 tooth for a bit on my 2024 TE 300. It’s the same ratio as a 13:49. I found first to be a bit lower than needed and found myself shifting into 3rd a bit too much. I found 13:52 to be perfect on my 2022. I’m wondering if with the 47 on the back of you’re primarily now in 2nd for mountain single track as that’s what I’m going for? I’ve also been told that with countershaft a bit lower than previous years that the 12 could cause excessive slider wear. Not sure if that’s a real risk or not. I also do big alpine scree slopes with my bike and stock 3rd is awesome for that so I’m nervous that the 47 will make 3rd be too low for that? Lastly, what do you think about a high comp head with stock gearing? I’m thinking the extra torque might make second almost perfect and would allow me to maintain my stock 3rd for those big scree slope climbs.

been using my 49 year old Mitutoyo calipers for many years to adjust chain slack....

Nice! Could have changed front sprocket by one tooth as well and got similar result. You should try a high compression head.

I would probably go to a 12 front instead, that way your axle moves back instead of forward. Axle forward makes for shorter turning but wheelies easier on hill climbs.

I don't mind aluminum sprockets, but I refuse to buy one that has the anodizing cut away where you need it the most(the teeth). I want the surface hardness that the anodizing brings to fight wear.

@dirtbikechannel you did this using the stock chain length?

That bike is so beautiful

Have you actually weighed this bike ready to ride with a full tank? Would love to see the actual number! Thank you!

Kyle, did you stick with the 47t? After my first two rides, I missed the second gear from my Ersberg xcw.

I’m currently running 13/52 on my 500 and it’s a single track beast. I’m wondering if I’ll do the same on my new 24 xcw.

Boa noite a todos,aqui no Brasil usamos coroa 52 e pinhão 13 nas motos off Road ,fica muito bom .

are you running a spark arrestor in this video?

Did you keep the 47 tooth on the back?

Shorter wheelbase also increases traction.

45??? dayum that was wayy too long!

Two bad you can’t just put a 12 tooth on, equal to about 2 1/2 teeth bigger in the rear.

Watching people work on bikes is almost therapy. I think it has to do with the fact that you can edit out any flubs.

ktm like all the new bikes and setup for riders around 68kg , if you're heavier than that by more than 8kg you need to change the factory settings, spring preload and or rate, static sag , and sprocket gearing.
