Polini Hi-Speed variomatik is a complete variator kit with a V-belt, two compression springs, two sets of rollers (6.9gr. + 5.6gr. 16x13), a set of trim springs and a variator. The included Hi-Speed variator is extremely powerful and ensures increased traction and top speed. This is done through improved runways and a generally better transfer of forces. The V-belt is made of a special material, which makes it very resistant to heat and ensures against the belt slipping.
Note: Fits only models with 13mm crankshaft.
