Vespa VMA Piston (2nd Over, 55.4mm)

Vespa VMA Piston for Vespa Scooters

This piston is made for Vespa scooters that use the VMA engine. At 55.4mm, it is a 2nd oversize piston. Like other Vespa scooter components, it installs in the same place as the piston it replaces. Picking the correct piston helps the combustion chamber seal properly, which matters for how the engine runs.

Signs It May Need Replacing

Consider changing the piston if you see heavy smoke, oil use going up, or lower engine compression. Worn piston rings often cause these problems and can reduce how well the scooter performs.
