Motorbike Sprocket

motorbike sprocket

Sprockets are most commonly made from steel to increase their longevity; aluminium is sometimes chosen for racing on rear sprockets as it is lighter, but it wears more quickly than steel. The front sprocket is typically much smaller and has between 10 and 18 teeth. The rear sprocket, usually the larger of the two, can have between 28 and 64 teeth. For some, highly modified motorcycles, a third sprocket is used to maintain tension though it supplies no additional power to the rear wheel.
