Vespa VNA Piston (54.6, 3rd Oversize)

Vespa VNA Piston for Vintage Scooters

This piston for the Vespa VNA is built to suit your vintage Vespa scooter. Its diameter is 54.6 mm, and it comes in the 3rd oversize. Worn pistons and rings should be swapped out to keep the engine running efficiently and to head off problems such as oil burning and weak compression. It is one of the vintage Vespa scooter parts that helps keep the combustion chamber properly sealed.

What This Part Does

The piston and rings are what seal off the combustion chamber. As they wear, you may notice smoke, higher oil consumption, and reduced engine compression. The piston diameter and oversize need to match your cylinder for the engine to work correctly.
