[QUOTE="HiG4s, post: 161159, member: 22165"] The stroke on the new KX85 and KX100 are the same, so I would suspect that the only difference is the cyclinder and piston from same year kaws. But I'm not sure. By AMA rules you can run to 85cc in the 80 class. One other thing you need to look at is the wheel size rule. In motocross at least, you can't run over a 17 inch front rim in the 80 class and the 100 has a 19 inch front which is the max size for the 100cc boy racer class. [/QUOTE]
