My girlfriend rides an 01' F4i we would like to swap the rear wheel out for one from a 600/1000RR. Shes a small girl and a 190or 200 tire would looks plain sexy. I refuse to let her run a 190 on the 5.5" rim but the 600/1000RR wheels are 6" and I was wondering if anyone here would know if a swap is at all possible.
