Vespa VMA Piston Ring (55.2, 1st Oversize)

Vespa VMA Piston Ring for Smallframe Scooters

This 55.2mm first oversize piston ring is made for classic Vespa small-frame models. It helps keep the combustion chamber sealed, which can reduce smoke, oil use, and low compression. Like other Vespa scooter parts, it installs in the usual position, so it works as a direct swap for a worn ring. For good results, the piston measurement, pin dimensions, and oversize rating all need to match your engine.

What This Part Does

The piston rings seal the combustion chamber. When they wear down, smoke and higher oil consumption can follow. Swapping out worn rings helps the engine run more efficiently.
