Polini Evolution transmission cover for Piaggio/ Vespa 50cc 2-stroke engines with 10 inch wheels.

Maximum air flow was the goal for Polini when they designed this cover. The high air flow keeps your transmission cooler, improving the life of your variator, belt and clutch while maintaining maximum efficiency. The die-cast aluminium alloy cover also gives your engine the Polini Evolution style.

The original kickstart & starter bendix can be used with this cover.

Please note: You will need to cut threads into the blind screw holes to fit the air filter cover!

Included: cover, air filter, air filter cover, screw set & dowels.

Polini 170.0311, equivalent to Piaggio 872203
