I do my best to research the part and see what machines it will work on. These are used parts so that means they will show you're normal wear, not new unless specified otherwise. This is a rotor assembly with the starter ring gear that was removed off 1990 Yamaha xl-v 540 sled had only 567 original on it when I found.
As you can see in the pictures it is nice shape, a little surface rust from sitting garage for all those years but excellent working condition.
This gear is no longer available from Yamaha.
