Minarelli horizontal Evolution Polini crankcase cover

Polini Evolution crankcase cover for Minarelli Horizontal.

The cover includes a system with a bearing that supports the drive shaft to prevent vibrations, and it is also reinforced with a plate, so the bearing does not come out.

At the front there is an air intake with a small filter that prevents the entry of dust, and at the rear there are holes to expel the hot air.

Designed in such a way that it is ideal both for modifying the aesthetics and for reducing the weight of the engine.
