Vespa V9A Piston (1st Over, 47.2 mm)

First Oversize Piston for Vespa 90

This piston is a 1st over size at 47.2 mm, made for the Vespa 90. It is a dependable swap for worn parts and helps bring back the engine's normal running. Like many Vespa scooter parts, it goes straight into the spot the original piston occupied. Keeping good compression and cutting down on oil use are the main reasons this piston matters.

Role of This Component

The piston and rings work together to seal off the combustion chamber. Once the rings are worn, you may notice more smoke, higher oil consumption, and weaker compression. Fitting a new piston is a practical way to get the engine running efficiently again.
