Piston, Polini 130 cc - 57.4 mm for Scooters & Mopeds

Polini 130 cc Piston for Scooters and Mopeds

This Polini piston suits 130 cc engines and has a 57.4 mm diameter. It is a practical replacement for a range of scooters and mopeds, helping to keep engine output where it should be. As with other scooter pistons & piston rings, its main job is to seal the combustion chamber properly. The kit includes rings, a wrist pin, and circlips, so fitting it is straightforward.

What This Part Does

The piston and its rings are what keep the combustion chamber sealed. Once the rings wear, smoke, higher oil use, and reduced compression can follow. Fitting a new piston can bring back the engine's efficiency and power.
