Quick installation, noticeable difference.
The best kept secret in the pro pits, our Anti-Vibration Bar Inserts have been a staple since we introduced them in 1999.
A discreet, but incredibly effective component to any serious racer or casual rider, our inserts do a great job absorbing the vibration transferred from the bars to your hand yielding less fatigue and arm pump. Riders have been installing in them in anything with handlebars from quads to superbikes with great results.
Constructed out of brass with an elastomer expansion joint mounted inside of the handlebars, rubber mounting the mass to absorb the vibration. The Anti Vibration Bar Inserts seal off the inside of the bar, preventing debris inside of your handlebar.

What’s in the box
- (2) anti-vibration inserts (built with 35mm long bolts)
|7/8" Aluminum (Renthal and most other aluminum 7/8")||ABI-200|
|1 1/8" Aluminum (Renthal Fat Bar, Pro Taper and most oversized aluminum bars with 13.5mm I.D.)||ABI-200|
|All Twin Wall / Double Wall||ABITW-300|
- Lightly Lubricate the o-ring and bar insert. To much grease will cause the bar insert to spin. Before installing in pro-taper style bars, remove the o-ring and install the insert to make sure that it fits all the way in. If it fits easily, try it with the o-ring on. The o-ring is optional, it may have to be removed on some bars.
- Install the bar insert by pushing only on the allen bolt with a 5mm allen wrench. If you press on the bar insert cap, you will not be able to push it all the way in. This will also damage the expansion piece.
- If installing with hand guards follow the diagram to the right.
- Tighten allen bolt snug, not too tight. Apply the grip over the bar and Bar Insert on the left side. Slide the throttle tube over the bar and Bar Insert on the right side.
Anti Vibration Insert Installation
When I first got these, it looked that it would be perfect for my Protaper bars. I am using the Raptor SE bend. The bar is thicker than usual 7/8 bars out there, which makes the ID be much smaller than standard, so a real challenge to add some anti-vibration weights to it. Be aware though that these Protaper bars taper even more ~ 3 or so inches in from each side. These FASST bar weight inserts are a tad thicker in the first inch of the insert, but it still fit the bar....until I cut an inch off each end of the bar! Then that thicker section of the inserts hit the thicker part of the bar (it is not gradual, just a step, on both the insert and the ID of the bar). It was a major bummer. So I had to grind down that thicker section of the FASST inserts to make it fit as there is no way to change the handlebar ID! I am not sure why these FASST Inserts are thicker in the first inch, there must be a reason for being, but be aware you will need to customize it if you are cutting your ProTaper bars. If you do not need to cut the handlebars, it will be 100% plug&play! I also added a cap at the end of these as i have open ended grips and the bare metal cap of these inserts were not what I was looking for (besides, they are meant to be hidden inside a closed grip anyway). I used the bolts that came with the caps which luckily for me were the same thread as the inserts, but a little longer as needed. These inserts are each twice as heavy as my stock bar weights so I am looking forward to riding and seeing if I can notice the difference.
I installed these on my DRZ400s/Protaper CR High handlebars with Cycra Probend handguards. What a difference! Now I have minimal vibration at highway speeds. Problem solved!
mounting handguards in rubber isn't a good idea, after a few rides, the rubber "squishes" out and o-ring fails, leaving the rider with less hand protection and a pound of brass rattling inside your bars?
