The KKBike Pinion

Superpinion is a reinforced motorbike pinion that can be mounted on the drive shaft of the gearbox. The technical problem analysed concerns the secondary transmission of vehicles that use chain, crown sprockets, and pinion gears to transmit movement from the drive shaft to the wheel, via a secondary countershaft. A crown sprocket and pinion system is a chain or gear transmission system, where the pinion is the smallest geara nd the crown sprocket is the largest gear.
