I removed the rear wheels from my R-Spec and saw an odd looking bracket that sort of sticks out into the wheel. Is that for scrapping mud off the wheel or what??

Yes, that is like rock/mud guard to keep foreign objects from wedging between the brake calipers and wheel. Rocks have wedged between calipers and wheels and punched holes into the wheel....no plug kit in the world will help then.

Thanks, Yamaha engineering impresses me.
