I am looking to see what other members have done for cast streetbike wheels on their XR R's. I have done some searching and see some posts about cbr wheels but no good info. If anyone has done it or has info on it please let me know. I would like to know about the eligible donor bikes including model and years along with tire sizes used. I have heard about modifying the bearings or making spacers but nothing solid. Also, what about the brake rotors and cush drive. Thanks.
