Vespa V9A Asso Piston (3rd Over, 47.6mm, Large Pin)

Vespa V9A Asso Piston for Vespa Scooters

The Vespa V9A Asso piston is built to help your scooter's engine run better. It measures 47.6mm across and has a large wristpin for a snug, accurate fit. It is one of the Vespa scooter parts that keeps the combustion chamber properly sealed. If your scooter is giving off smoke or using up oil, a new piston may be the fix.

When to Replace It

Worn piston rings often cause higher oil use and reduced compression inside the engine. Swapping in a new piston can bring back lost power and stop smoke coming out of the exhaust. Confirm that the piston diameter and pin size line up with your cylinder before installing.
