The Polini Kevlar Evolution V-belt is made of a strong material, which ensures good durability and at the same time ensures it has difficulty slipping. It is a powerful upgrade over the original V-belt, which can be used on both completely standard and tuned engines. Dimensions: W: 19.5 X H9.5 XL: 810mm. 28º. NOTE: Fits only from Hiper2 onwards.
