Don't worry about calories, these donuts taste terrible...but your hands will love you for using them! The Risk Racing Grip Donuts will prevent blisters from occurring on each of your thumbs, which leads to pain and bloody grips. Slide the motocross grip donuts over any dirt bike grip and protect against blisters. Ride longer and more safe with protected hands! Great for Motocross, Supercross, Hare Scrambles, GNCC, etc. Fits all grips. Includes one (1x) pair of Motocross Grip Donuts.
