Polini 9 Roller Evolution 3 Hi-Speed Variator Kit
This is the latest version of the extraordinary nine roller variator kit from Polini. The main improvement is a lubrication system that features a case hardened nickel bush pin with a large internal pocket that contains a special grease. The addition of a spring inside the internal pocket allows the grease to distribute evenly on the pin even under extreme racing conditions. There are other changes too like the new nylon and aramidic fibre coated rollers to further help roller sliding. All in all, this kit will not only improve transmission effectiveness, it will enable lower service intervals too.
Available soon for Piaggio / Minarelli 50-94cc engines.
