Vintage Vespa Cylinder Stud 7mm - Largeframe & ET3

7mm Cylinder Stud for Classic Vespa Largeframe and ET3 Models

This long, double-ended cylinder stud is made to hold the cylinder assembly to the engine case on a range of older Vespa models. It suits Largeframe and Smallframe scooters built during the 1960s and 70s. Listed among our vintage Vespa scooter parts, this stud plays a key role in keeping the engine assembly secure and running dependably.

Construction and Design

The stud has a 7mm diameter and is threaded at both ends, with an unthreaded section in the middle. This layout lets it seat firmly when the cylinder assembly is fitted to the engine case. Every engine needs four of these studs, and they are meant to be paired with matching 7mm nuts and washers, which are purchased separately.

Replacement Considerations

When you are repairing or rebuilding the engine of a vintage Vespa, this stud is a required part. Note that it does not work with GS, SS, handlebar-style Rally, or P200 models, since those use 8mm studs.
