Take a look at the 08 swingarm set up the older model busas have a brake caliper hanger that hangs from the rear axle, which is one of the spacers on the older wheels. If I am not mistaken the 08 busa runs the rear brake off the swingarm, so naturalty your spacers are gonna be different. This is what I had done in the past with a set of PM wheels that I had on my old zx7r, but there is no garuantee that it will work in your situation. you must first make sure that your rear brake is the same outside diameter and counterspaced to the same location as the 08 brake is (it would probably be best to bring your factory wheel for a reference). If so then I would bring the factory set up bike to a machinest along with the PM wheels. alow him to take the factory measurements and then he can make the appropriate spacers, it shouldn't cost much. On the flip side if that is not possible then I would buy 08 specific wheels, I am possitive that they make some as I saw several 08 busas at a recent bike show all running PM wheels.
