Hey guys first post here
Just wondering if anyone has any solutions for vibration on a 250 2 stroke, love mine and have filled the bars with expanding foam and bought the pro taper grips that reduce vibration, they gave a good improvement as my hands cramp half due to vibration and half due to just not riding enough lately, but anyways, doing that improved it loads my hands didnt cramp up as quickly (armpump isnt an issue anymore its hand cramps haha).
I have heard of Nekken SFS tripple clamps for reducing vibration and theyre meant to be pretty good.
So anyways, what have you guys done to stop vibration through the bars and how much of an improvement was it?

Get rubber mounted bar mounts before dropping money on triples.
Edit****
It’s not so much of an issue on hardpack tracks, more deep tracks due to just not backing off as much and being higher up in the Rev range
Do these seem similar to what you have? Ill have to get a set if theyre that good! Love the 2 strokes to much to get 4t haha
The Shop
Check swing arm bolt, engine mounts and engine to frame bolts. Use proper torque spec.
An extreme idea when you rebuild the engine, you can get a crank trued and balanced to the the piston. I believe crankworks is the place for that.
I’ll go over the engine mounts again, I’m quite religious with checking the bike over before every ride but I’ll double check it all, hopefully those bar mounts will work too!
Also what handlebars? These make a huge difference.
An easy mod is the PHDS system. They come with 'medium' hardness inserts, so you could even make them more supple with the softest inserts.
A little more hardcore would be having the crank balanced as CarlinoJoe mentioned.
It’s a 2011 I’ve got renathal twinwall bars but the clamps are standard so it’s essentially hard mounted as here’s no rubbers, I put some thin rubber strips in the bar mounts but they’re just not the same as buying the real thing
Just adonised mounts as you can see, also grips are those nice padded pro taper ones now and they improved it
What you're running right now is basically the stiffest, most unforgiving bar+clamp combo possible. The twinwall is waaaayyyyy too stiff for a mere mortal, and the (Mxbonz?) clamp just makes it even worse. Changing to a Fatbar with PHDS clamps will make a world of difference. The KTM ones are the same as Xtrig, just different branding. Get whichever ones you can get the cheapest.
