Help, I have recently purchased a 2006 955 and after only 20 minutes riding my right hand thumb is hurting and I have pins and needles in my hand. I'm not holding or gripping tight but its got to a point where the pain in my thumb still hurts even if I don't ride the bike for a day. I haven't really noticed excessive throttle vibration compared to my previous Suzuki. Would heavy bar ends help? Any other suggestions?
