This is a top quality BGM front sprocket with 19 teeth.
Sorry, no longer sold! Please see our selection of Indian sprockets......
This is either used to slightly improve the the Gp200's top speed on an engine that originally use 18/47 (in which case you would need a worn stretched 82 link chain or use my chain tensioner and an 83 link IWIS chain) or it can be used with a 46 tooth rear sprocket (in which case a new 82 link chain should be used)
