Phil Little (Bike Genius at large) at Omar's Dirt Track Racing builds custom rear sets for the XS from RAASK and TORRASEI components. The price is on the mark (389.00 w/shipping) and the quality is straight up, includes a lovely substantial aluminum mount plate, easily bolts right on with no BS, maybe have a bit of time using kick start. I think he has some japanese sets for less money, but why bother. The phone number is 763-745-2255. The web address is www.omarsDTR.com He has other cafe bits and a lot of tasty tracker treatments as well. Check it out. Good Luck.
