Piston (5th Over, 58.0mm) for Vespa VBA, VBB

Piston Designed for Vespa VBA and VBB Scooters

This 58.0mm piston is a 5th oversize unit made for Vespa VBA and VBB scooters. Its job is to seal the combustion chamber, which helps the engine run as it should. Like many classic Vespa components, it installs in the same spot as the original piston. Think about swapping it out if you see signs such as heavy smoke or the engine using up oil.

Signs It Needs Replacing

The piston and its rings work together to keep compression up. When the rings wear down, the engine may burn more oil and lose some power. Fitting a new piston can bring back the engine's normal efficiency.
