Has anyone else had any issues fitting Renthal Grips?? The clutch side handlebar grip was fairly easy to come off and to fit the new Renthal Grip. However, having huge issues trying to fit the throttle side!! Even rang BMW and they said you cant remove them!!??? Is that correct? Has anyone on here fitted Renthal grips to their bikes?? Ive fitted soft Renthal grips to ALL of my old bikes as i prefer the feel over standard grips. But ive never had this sort of problem before. Any help or advice much appreciated!!
