Polini Evolution gear transmission cover Minarelli

Description

The Polini Evolution gear transmission cover is a high-quality aluminum cover designed for Yamaha / Minarelli Horizontal 50cc scooters with a long engine case. Compared to stock covers, where drive shafts slide directly on the housing material, Polini solves this issue with an improved construction that significantly increases gearbox reliability and performance.

The cover is equipped with a fluorocarbon sealing ring (FKM) and an O-ring, ensuring better sliding, optimal sealing and easier maintenance. It is suitable for use with both stock gears and extended gear ratios, while also allowing the installation of oversized variators.

The black finish and engraved Polini Evolution logo provide an aggressive racing look that perfectly matches higher-performance tuning setups.
