Vespa VMA Piston (55.4, 2nd Oversize)

Vespa VMA Piston for Vespa Scooters

This piston for the Vespa VMA comes in a 55.4 bore with a second oversize. It is built for particular Vespa scooter models and helps keep the combustion chamber properly sealed. Like other Vespa scooter parts, it installs in the spot the original occupied, so no modifications are needed. Consider replacing it if you see oil being burned, smoke, or weak compression.

Purpose of This Component

The piston and rings work together to keep the combustion chamber sealed. When rings wear out, the engine may burn more oil and release smoke from the exhaust, so swapping them in good time helps the engine run as it should.
