Re: Pit Bike
It looks like #25 sprocket, if your chain is real long you can add a spring loaded chain tensioner, to keep tension on the chain as the swingarm goes up and down. I would look for 10Ft, 3 meters or so, of #25H chain and a #25 master link or two. They have gold colored chains and masters too.
