So I’ve been doing some reading and thinking a different triple clamp offset might help me out. I’m riding a 2011 YZ250 smoker and I love everything about it except it’s cornering. I feel like I sometimes struggle to get the front end into a rut and other times I have a problem with the front end riding out of a rut. If that makes sense. I have the stock triple clamps on currently (25mm offset?). I was looking at various brands like Applied, Ride Engineering and also found these Neken clamps. The neken clamps are for a 14-18 yz250f but what I like is there 22mm offset which is what will help sharpen the steering up. I’ve thought about sliding the forks up in the clamps but I don’t want to loose straight line stability. Wondering if this will fix my problem or if I just need a better technique haha.
Here’s a picture of what I mean when I say it’s “riding out of the rut”

(it says pre-order only for Yamaha, but we do have one blue set in stock that fits your bike)

You can press the stems out of the clamps and swap them to accomplish the same thing for around $150.
I would double check what the offset is on the four strokes though.
All that said, it can certainly be done but you'll need a good machinist to bore out the upper triple clamp 2mm, press out and switch steering stems, go with the new fender style, and buy a new brake line clamp.
I am looking for some clarity on this. Can anyone confidently state which clamps fit with what?
I don't mind having the tops machined, but direct fit would be nice (aside from the stem press).
I want to keep 2 sets of clamps to go back and forth if I want. Any help is appreciated.
If turning is your issue, then I've been telling guys with YZ250's to set their sag where they like the rear suspension feel. Anything over 100-103mm of rear sag take it out of the front. So, if you set your sag to 105mm then slide the forks up 5mm in the clamps. If you like 107mm then slide the forks up 7mm in the clamp. You can do this up to about 10mm. If you want to run more than 110mm of rear sag then you have other issues.
This is all assuming that you have decent balance on your current suspension set-up. If you weigh 200# and you are on the stock rear spring then that's more of your problem turning than clamp offset and new clamps aren't going to fix it.
BTW: The YZ250X has a steeper steering head angle as do the 125's.
Merry Christmas to me!!
First ride of 2021
Anyone still looking, the Luxon close out upper clamp and a stock 450F lower is the cheapest way into a set of 22* clamps.
Pit Row
Heck I even did my ‘18 250F clamps too
I don't mind doing that really but it's just added cost I could live without. I would be interested in painting them but I don't see that holding up. Nothing worse than a ghetto looking bike.
Clamping area is 56mm upper and 59mm lower for the 2 strokes.
The Luxon are beautiful, super light, superior bar mount setup (rubber mounted) , Ti hardware and bolt on correct diameter for 2-strokes. Billy the owner, is also awesome and a great asset to the forum with his tech posts.
I bought a 450F lower for practically nothing, combined with the Luxon upper it's the cheapest way to try out the offset change. I bought a "clear" upper, and vapor blasted/shaved the casting line off the stock 450F lower to clean it up.
As far as the 450 clamps go, I'll just re press the stem and bore the top clamp and be good to go though, right? I even see some users on TT that don't even swap stems. They seem to be close enough in length. I'll change the stems though.

I also found some '22 in brand new condition for like 155 on mx locker.
You can see which bikes used what on our website under Bike Fitment and the additional info tab:

I don't have data for anything before 2012 on the four strokes, though, so I'm not sure the 2011 clamps are 22mm offset or not. If you find a set of 22mm offset four stroke clamps, you'll need to bore out the top clamp an additional 2mm in diameter and swap the stem from your two stroke.
If you don't have access to a machine shop for the boring, our closeout top clamp is the easiest route forward, but it won't match the bottom clamp, of course.
