mine's in for winter with the tires off so i measured it. 7.5 inches 190.5mm i can't see a 200mm tire fitting without modifying the swingarm. the frame tubing would need to be pushed in 5.5mm at least on each side. just take a feeler gauge and measure your stock tire clearance to the swingarm, there's is definitely not 10mm on each side to accommodate an extra 20 millimeters of tire. i just don't see it happining
this guy used a metzler 880 200/70-15 but metzler over sizes their tire widths it's not a full 200mm probably closer to 190 but here's the link http://s325.photobucket.com/user/bleheny...2.jpg.html
anything over 180mm is supposed to go on a 6 inch rim so you'll be really pinching it to fit your rim which is not a good thing.
