Has anyone ever used arlen ness throttle bearings on aftermarket grips? I would like to know how good they work.

 

I put the Ness Grips on my old bars.It was not a noticeable difference to me.If you use them be prepared to cut 1/2" off the throttle side of your bars and I sure that the bearing only works with Ness grips that are set up for it.It's actually a plug that you put inside your bar,the bearing is mounted at in the end of the grip from the factory
