Drive side, ULTIMATE version, Race-Tour MB brand

Specially designed drive side bearing from MB Scooters Mark Broadhurst, this is their ultimate Lambretta drive side bearing for the crankshaft.

It’s a high-quality, touring-type main bearing, now comes fitted with an additional seal. The seal is installed with the spring facing the gearbox or you can fit facing away thus giving two types of extra protection, 1, helping to stop gearbox oil getting into the drive plate area and 1, stopping air pressuriasation gettin behind the bearing and pushing the gearbox oil out.
