Our record on this one is brief and doesn't tie it to a specific model or year. The manufacturer tag that came through with it doesn't match what a sprocket actually is, so don't read anything into that. If you're matching this to a build, best to check tooth count and shaft fit against what's on the bike now before you order.
Call the shop if you want us to confirm fitment before it ships.
