Front sprocket 420 pitch Derbi Variant Start 3 MJ Corse

Front sprocket 420 pitch from manufacturer MJ Corse for Derbi Variant Start 3.

If you want to convert the bike to a Chain, whether for daily use or competition, this is the ideal component.

It is manufactured from high-quality untreated steel , providing extra strength and durability.

The front sprocket has a 420 pitch, which should be taken into account when choosing the chain.

When replacing the front sprocket, we recommend changing the entire transmission kit (Chain, Front sprocket, and Rear sprocket).
