It's a 2003, it's had a 480 big bore cylinder kit pit on it, it has upgraded radiators, radiator guards, hoses, an hour meeter, temp gauge radiator cap, upgraded valves, cams, and oil filter cover (to improve oil flow) and I think the springs were also done, so it's been built well for to be the 480. Other than that if comes with the original cylinder and piston, cams, and valves so it can be put right back to a 450 if wanted or if the 480 kit ever has issues. It has new white plastics, and the old blue ones with American flag graphics lever guards, an aluminum skid plat, and new levers as well as spares. The 480 kit has less than 7 hours on it so it's got lots of life left
