Never seen that particular product before, but I have the Star bar end weights and the Iso grips which eliminated my problems with numbing of my hands. I had the most problem with the throttle side, but no more.
Never seen those before either. Not sure if I want to mess with the internals of the forks though.Yes, me too - my throttle side hand takes a beating and goes numb inside of an hour. There is also a write-up about the Intiminators-I copied the link below. Any thoughts on that for vibration also?
