Piston (38.6mm) for Scooters & Mopeds

Piston for Scooters and Mopeds

This 38.6mm piston suits a range of scooters and mopeds. It helps seal the combustion chamber. Riders often look at scooter pistons and piston rings when they notice smoke or oil being used up faster than normal. Choosing the right fit keeps the engine running as it should.

What This Part Does

The piston and rings work as a team to keep the combustion chamber sealed. When the rings wear down, the result can be heavy smoke, more oil use, and weaker compression. The piston diameter and pin size need to match your cylinder for the part to work correctly.
