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.

They do help reduce vibration some but they are easy to install but make sure you have new grips to install after wards.

Great Product Support

FASST makes great stuff and great product support. I am confident these inserts will help for anyone riding a 2 -stroke that gets arm pump. The only problem is if you cut your bars down (mine are 30") the insetrs will not fit. I ended up cutting a couple inches off th ends of the inserts to get them to fit far enough into my bars so that I could install my bark busters. The other option is to get them machined so the diameter can be made smaller so that you can shove them further into your bars. If you don't use bark busters you may be o.k. In any case I almost had to cut each one in half to get them to fit which seemed like a waste but they seemed to have helped a great deal. They are very well made parts and I hope some day to be able to afford their Flex bars as well.

A: These are specifically made for the Renthal Twinwall Handlebars.

According to Fasst Company's application chart the Standard 7/8" Inserts will actually work with Pro Taper 1-1/8" bars like the Metal Mulisha Bars.

I would recommend checking the Inner Diameter of the hole in the end of your handlebars just to be certain. Fasst company notes that the bars must have 13.5mm I.D.
