from what i have been told the 05-06 wheel's are lighter (not sure about the 07-08 but i would guess so) the rear is a direct swap, using the spacers from the 03-04, and the front is not, i cant remember what the diff is, but i know it is possible to use the front from the new modle. i dont have those newer rims on i bought 2 used magnesium rims on put them on my 03 1k :shock:ohhhh damn did it change how fast the bike turns, i did the same thing to my old 1100 and with the same result only i had PM race light rims i put onit. i realy need to do a bare rim weight test some day when im swappin tires though. to put this on paper. i can say on the rear rim with a stock rotor on the stock rim and a completely burnt off on all sides pilot power race med compound tire on it, compaired to a marvic magnesium rim with a galfer wave rotor and Ti bolts and a almost brandy spankin new Bt014 tire on it, the mag rim set up felt a bit lighter using just my hands holding them both at the same time, realy the only good way to test would be to have the same tire on or no tire at all and weigh them both, i can say though from swapping the tires out on back to back rides it is very very noticeable during the ride, the bike is waaay more flickable from side to side and the front end is very ehhh wheelie happy now, well like it already wasnt but not its just stupid
