Our 9 tooth chain sprocket is commonly used on Go-Karts and Mini Bike custom setups. This 9 tooth chain sprocket is used with size #40, #41, and 420 chain. You may also find that our sprocket applies to 20 & 30 Series torque converters. It uses the common 5/8" bore (inside) diameter that matches up to the 5/8" axle shafts on many popular models.
This is a Type C sprocket where the 5/8" thick hub is centered equally on both sides. (Type B sprockets have the hub offset to one side.) In addition, the shaft key is an integral (or "broached") part of the sprocket.
