Description
Asso Piston for Vespa VNX, VNB, VNC
This Asso piston is a 3rd oversize unit with a 53.1mm diameter, made for the Vespa models listed below. Its job is to help seal the combustion chamber, which the engine needs to run properly. Like many vintage Vespa scooter parts, it is intended as a dependable swap-in for a worn piston. Before fitting, confirm that the piston diameter and pin size match your cylinder.
What This Part Does
The piston and rings work together to seal the combustion chamber. Worn rings can cause smoke, higher oil use, and lower engine compression.
