BJ 12a Sprocket

This is a new BJ 12a output sprocket for an Albion lightweight transmission. it has 14 teeth and is for the #40 chain. This is the correct sprocket for a Rokon 2 wheel drive motorcycle. It can also be used on an older British motorcycle but it is too wide to work with a #41 chain. The seal diameter on this sprocket is 1 1/8" instead of the original 1 5/32" due to the original seals being unavailable. The A 35/1 seal is the correct diameter for this sprocket.
