I sthis your first bike? If so you might just have to get used to it. Condition yourself so to speak. When I first started riding my right hand would go numb as hell. But in my case it finally quit. You can try one of those cramp busters. That way you can let go with your fingers but still maintain control. Good Luck!
i don't think i've got a death grip. but, it has been 20 yrs since i had my last bike. i do wear a good pair of leather gloves. the grips that are on this bike are somewhat square and it does put a odd twist on the wrist. thanks for the input
