Specially-modified high-performance drive belt. This belt has been made as thin and elastic as possible for an extremely effective transmission that dramatically reduces drag, and as a result, helps to reduce battery voltage draw. The belt is specially hand ground on a special machine for minimal thickness and flexibility, without affecting lifespan.

To fully enjoy the benefits from these high-performance belts, make sure that all transmission ball-bearings are absolutely clean to reduce drag and friction.
