If you suffer from arthritis or find that your hands go numb while riding, foam hand grips may be the solution to your problem. Our foam slip-on handlebar grips expand the diameter of the factory grips providing you with extra padding and comfort. This not only relieves strain on arthritic fingers, but serves to reduce road vibration which can cause tingling in your finger tips. These grips are easy to install, cheap, and even work in conjunction with you factory Can-Am Spyder grip heaters, if equipped.
