VIDEO | BGM Silicone Gasket fitting

First for Vespa, now also for Lambretta.

Gaskets produced with a silicone bead should be familiar to anyone who works on modern motorcycle or scooter engines.

The chief advantage of this system is that they provide improved sealing without the need to add any additional gasket sealing compounds, which makes both assembly and removal much easier.

The chief disadvantage of this system, if you have even bought a set of gaskets for a Japanese engine, is that they are expensive. Adding the silicone bead is a specialist process.

Scooter Center’s BGM brand has struck a decent balance between cost and quality with these Italian-made composite gaskets. In addition to the Vespa PX versions they are now also available for Lambretta side casings and Mag housings.

Given the wear, tear and repairs on old Lambretta casings especially, they are prone to irritating leaks because thread repairs tend to diminish the gasket surface area.

Use

The silicone gaskets can be used either dry or greased. The advantages of greasing them is that they can be held in position but grease also eases disassembly.
