This is the new 46T clutch bell sprocket crownwheel for Lambretta Lui Vega Cometa 75cc models and is also adaptable for Lui 50cc models. Produced exclusively for Casa Lambretta to very high standards, these are superb and a real breath of fresh air as these are always worn out when you go to overhaul or restore an engine.

There are two types of clutch spocket crownwheel assemblies for J range and Lui Vega Cometa models, with either a bronze bush or with a needle bearing. This clutch crownwheel is for models with a bronze bush (Item: 915).
