Piston 177 cc (63.4 mm First Oversize) for Polini for Scooters & Mopeds

Piston for Polini Scooters and Mopeds

This first oversize piston is made for Polini scooters and mopeds. The kit comes complete with rings, a wrist pin, and circlips. A good seal in the combustion chamber matters a great deal, and this piece belongs to our range of scooter pistons and piston rings that support steady engine output. Swap out worn parts to prevent problems such as smoke, oil use, and lower compression.

Function of This Part

The piston and its rings jointly keep the combustion chamber sealed. Once the rings wear, smoke and higher oil consumption can follow. Installing a new piston helps the engine run efficiently.
