This is a rear wheel assembly originally from a 2006 Kawasaki ZX6RR, same as ZX6R. FITS 05 and 06 models. This was our race spare, was ordered brand new with bearings, seals and brake rotor. **Only thing you need to mount it is your wheel spacers and sprocket carrier w/dampers** Only one season on it, has been in storage for the last year couple years. Comes as shown with a used Bridgestone BTO-02 race tire. I'm not certain but I think this wheel also fits 07-08 bikes with the appropriate spacers. Check with a dealer before bidding please.
