Vespa VNA Piston Ring (54.2 mm, 1st Over)

Vespa VNA 1st Overbore Piston Ring

This ring is made for Vespa VNA scooters and is sized at 54.2 mm, which corresponds to the first overbore. As with other vintage Vespa scooter parts, it goes straight into the cylinder in place of the component that was taken out. You may need a new one if you notice symptoms such as smoke, high oil use, or weak compression.

Role of This Part

The piston rings help seal the combustion chamber. When rings wear out or get damaged, the engine can lose performance, so swapping them in good time helps keep the engine running efficiently.
