Asso, Piston Ring (55.0) for Vespa VMA, VMB

Piston Ring for Vespa VMA and VMB Models

This piston ring suits Vespa VMA and VMB scooters. Its job is to seal the combustion chamber properly. Smoke, high oil use, or weak compression can point to a worn ring, in which case replacing it may be worthwhile. You can find it among Vespa scooter parts that help bring back engine output.

Function of This Part

The rings keep the combustion chamber sealed. When they wear down, problems such as smoke and lower efficiency can follow. Confirm that the piston diameter and pin size line up with your cylinder for the best fit.
