I am planning on buying a brand new 80cc motocross dirtbike by christmas, and I wanted to know how it will keep up with high performace quads like the 400ex in speed, jumping, and handling? How about a 250r, mohave, and other sport quads? I know I will need some practice before I get good with a 2-stroke bike. I am planning on getting a 2001 KX85. I would get a lt250r, or tectate 4 but it is cheaper to get a new mx bike(not to mention how hard it is to find a 250r in nice shape for a decent price), and my xr185 is getting too old for me. Does anybody have an opinions on this bike?
