The front wheel is a direct bolt on from 2008 to current. For 2007 and under, you need to change either the axle or the bearings. The brake rotors are also different from 2007 and older bikes because of the Brembo brake changeover in the newer bikes.
I know the front should if you make adjustments for the 25mm axle....not sure about the wider rear. However these came off of a Non-ABS bike
They'd definately make your bike stand out; I've yet to see any on a RK...
I put a set on my 05 RK, I ordered a 25mm axle and 08 spacers and put my old rotors on,it bolted up no problems. I haven`t got the rear one on my bike yet.
