    Excl. Tax: £53.00 Incl. Tax: £63.60

    Polini Evolution Gear Box Cover - Piaggio 50cc POLINI EVOLUTION GEAR BOX: PERFORMANCE AND RELIABILITY The Polini Evolution gear box is the new gear case die-cast in aluminum, developed for all those who own 50cc scooters equipped with long-case Piaggio or Yamaha- Minarelli engines. Compared to the original case it can be fitted on the middle shaft bearings and wheel shaft. It improves the reliability and the performance since the sliding problems of the two transmission shafts disappear, that on the original case, slide directly on the cover material. It is supplied with a retainer made of FKM (Fluorocarbon rubber) with inserts in PTFE (Polytetrafluoroethylene) at low friction coefficient specific to reduce the fiction and improve the sliding of the primary gear and with OR gasket to replace with the original one to make the servicing easier. The Evolution Gear Box can be fitted using both the original gear and the longer gears and it allows to fit different upgraded variators. The design is definitely aggressive thanks to its black color and to the “Polini Evolution” motif written with relief printing. Learn More
