Great quality but did not fit gsxr600

Like the title says I asked before purchasing them wether they would fit my bike and the only answer I got was they are for all aluminum handle bars. That answer was very vague. I guess I'll return them.

These work really well!!

Installed these on my 2015 Husqvarna TE 300. This year of 2 stroke vibrates enough that I was having tingling in my finger tips. 2016 updated the 300 with counter balancers. So I found these and found that they pretty much eliminated all vibration in the stock handle bars. Let a couple of friends that have a 2016/17 TE 300ride my bike and they said it works better than the stock 2017. Side note, to get the rubber O ring to stay placed on the brass piece, apply a small amount of grease to the inside of the handle bar and the O ring with not roll and come out of the grove on the brass piece. Again, well worth the money!!!

2 strole vibrations

I've used this product before (I forget to remove them when I sold the bike) These things work, no doubt about that, Maybe they reduce vibration around 40/50%. That's significant and they''re easy to install. I've also installed KTM PHDS Bar Mount (available through Motosport) that a friend gave me and now I've gotten rid of about 80% of the vibration.

Fasst Company Anti-Vibration Inserts

After some minor alterations to retain my existing bar ends the inserts slide right in my Suzuki stock handlebars. Being a big single cylinder motorcycle every little bit helps and they seemed to remove the high speed buzz at interstate speeds.

No big change

Bought these so I could get my brushguards to work with renthal twinwall bars and they work for that however if your buying them to relieve some vibration save your money no noticeable change

Didn't fit with MSR handguards

I couldn't get these to fit with my MSR/Enduro Engineering style handguards. They were well made and sturdy. The small o-ring fit in my stock KTM bars - the end mounts just wouldn't work with the guards.

Anti Vibe

I first started using these inserts five years ago on my 96' YZ 250 with Renthal CR Low 7/8 bars and I continue to use this product on my 07' KX250F I havent had arm pump since I first purchased them back in 2006! Amazing product!

It only takes about 50% of the vibration, but it does halp.

It works

A great additon to my fat bar. They make a difference. I'm not sure what it is the handle bar, anti vib inserts or the few tums I take every time I go out but by hands feel much better and no more arm pump.

A: All of these bars have a 1 1/8 diameter tube which tapers down to a 7/8" tube at the ends of the bars. These are standard measurements for oversized bars. All 7/8 grips will work with Renthals and all stock handlebar mounts in KTM's lineup will allow the mounting of Renthals.
Q: Hi. Do they work w 2015 ktm 1290 super adventure stock handlebar that is currently fitted w stock handguards?
