Asso Piston (55.2mm) for ET3 for Scooters & Mopeds

Asso Piston for ET3 Scooters and Mopeds

This Asso piston is built for ET3 models and is a valuable part for keeping your scooter running well. It helps seal the combustion chamber. If you notice smoke, higher oil consumption, or weaker compression, a new piston may be the fix. You can browse our range of scooter pistons and piston rings for other options that affect how efficiently your engine runs.

What This Part Does

The piston and rings work as a team to keep the combustion chamber tightly sealed. When the rings wear down, smoke and extra oil use can follow, and engine performance suffers. Matching the piston size and pin specification to your cylinder is necessary for it to work correctly.
