Better sproket

This used XR100 I bought hav a sunstar on it. I didn't know a steel sproket could be soft? This JT brought it back to at least stock or better. Thanks JT!

Fit on my 96 YZ-80.

The sprocket worked fine as a replacement on my '96 Yamaha YZ-80. I haven't used it long so I don't know how long it will last.

This is a good and cheap item. It works well, especially for the price we paid for it. Recommended.
