Vespa VLB Asso Piston (Std, 57.4mm, 3 Port)

Vespa VLB Asso Piston for Vintage Scooters

This Vespa VLB Asso piston is made for classic Vespa scooters and measures 57.4mm across, with three ports. It plays a key role in keeping the engine running well. As with many vintage Vespa components, it sits inside the engine and helps keep the combustion chamber properly sealed. Swapping out worn pistons and rings can help stop problems such as smoke, high oil use, and poor compression.

What This Part Does

Working alongside the rings, this piston keeps the combustion chamber sealed. Smoke or a drop in engine performance are common signs that it may need replacing.
