Rear sprocket made of aluminium for Derbi Variant, 420 pitch, MJ Corse

Rear sprocket made of aluminium, 420 pitch, from manufacturer MJ Corse for Derbi Variant.

The rear sprocket is responsible for transmitting power to the rear wheel. It is made of aluminium, which means you reduce weight in the transmission. You will notice the engine feels freer, allowing it to rev up more easily and making throttle response quicker.

Changing the rear sprocket allows you to adjust the gearing according to your needs, whether you want more acceleration or for the engine to rev higher.
