Variator – Polini Hi-Speed Evolution (13mm)

The Polini Hi-Speed variator is the safe choice if you want to upgrade to a better and more powerful variator. Thanks to the variator’s optimized roller tracks and overall high quality, in combination with e.g. a Polini Sport 70ccm, it will provide significantly improved traction and help increase top speed. Includes two sets of 19 X 15.5 rollers of 3.2 grams and 3.8 grams respectively, and a 20kg compression spring.

NOTE: For models with 13mm crankshaft.
