So having ridden my new YZ250 and being on 4 strokes for so many years I forgot how much this bike vibrates through the handlebars. What is if any products will help reduce the vibration the most. Best bike ever but man my hands are beat. Course I'm old as dirt...thanks

Faast flexx bars. thicker grips - I run the odi rouge non lock one. Very thick and lots of cushioning.

Things may help but it’ll still be a vibrating, smoking jettable dinosaur.

Spin some laps on a CR500 before, then it’ll seem like it hardly vibrates at all

Do the new ones come with rubber mounted bar posts? I have 450 clamps on mine to be able to fit some 49mm showa forks but the stock ones were not rubber mounted posts (2013).

Loosen your engine mounts and look to see if there is any gap between engine and mounts with tension off the bolts. If so, shim the gaps.

True.

But, things like a PHDS system ( I've WP forks on my 500), Soft grips, and , more importantly, a relaxed pair of hands holding them makes things fine.

That final point, is the key on any bike, with a bit of vibes to it..

This.

Last year I picked up this set of Ride Engineering 23.5mm offset triple clamps and bar mount with the yellow poly cones on a Black Friday sale. Noticeable reduction in vibration through the bars and not to mention this bike corners great now. Besides a head mod for this bike, this was the next best thing I’ve done to it

Pro taper Evo bars and renthal tapered dual compound grips are my secret sauce. Although I rode something with mako360 mounts yesterday and didn’t feel any vibration so that may be a good idea too

X2 on the PHDS. Don’t really notice much vibration anymore. And don’t read too much into people saying they slip or twist when wrecked. I’ve tested that out plenty of times. But for cheaper option I would try thicker grips first.

The Yamaha two strokes come with solid mounted bar mounts. Why Yamaha won't update the chassis of these bikes is beyond me, especially when it's such an easy parts switch from their four stroke line!

Anyway, replace the triple clamps with pretty much any brand that uses rubber mounted bars and the vibration will be dramatically reduced. If this is for motocross, then look at going to a 22mm offset while you're at it.

Some years of 4 stroke stock clamps can be fitted that have rubber mounts. But do your research because the fork diameter, offset, and fork spacing (wheel spacers) change between years. You’ll also have to press out and in your yz250 stem because it is a special length not used on other models.

Cheap fix: Pro Taper Evo bars (not the Contours) coupled with A'ME glue on grips; they're the softest around in either half or full-waffle options.

More expensive options: Find a way to go rubber mounted on the bar mounts or complete triple clamp assembly, with X-trigs' PHDS system and Luxon's offerings being the most high tech...

I x2 this. These triple clamps took away some of the vibration and improved handling (win/win). Also throw on pillow top grips, that helps as well. Also when I rebuilt my engine, I sent my crank to be balanced. My bike still vibrates, but its now much closer to my 2006 CRF450 now.

You have two options here.

A. Throw some money at it, get some fancy parts and cut down on vibration by about 20 percent. The outcome is you having a super sweet trick looking bike that vibrates almost just as much as it did before.

B. Get used to it Over the next two months and save your money to spend on entry fees, tires and gas money for going to those sweet tracks that are a few hours away without your wallet squawking like a mashed cat.


Either option is acceptable

Buy a KTM 250SX. It has a counterbalancer and vibrates less than many 4stks. 🤭

Also have a YZ250 and just ordered a pair of blue Luxons. I've not really noticed vibration being too bad but the rubber mounted bar clamps have to pass less vibration through than the stock rigid clamps. Primary thing I'm wanting to check out is how the bike will steer with the 22mm offset.

Another bike I occasionally ride at vintage mx events is an 85 RM250. When I get on the old RM, the ergos feel pretty funky for a few laps but right from the get go ...it's apparent the old RM steers so much better in tight corners than the the modern YZ, even thought it sets up just has high as a modern bike.

Called Lexon with a few questions and Billy picked up. Nice guy...answered a few questions and confirmed they have the clamps I need in stock! Looking forward to checking them out!

I run balanced TMR stroker engine with balanced 11oz FWW, Luxon clamps and FASST bars with softest inserts. I ride very rarely these days, so every little bit helps. Very little vibration with this setup.
