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.
