lol, I raced on one earlier this fall. A friend of mine organized a pit bike race on his private property and I was loaned a fairly beat one to participate. Really can't complain about the little thing. My 210 pounds beat on it all day and it just got better and faster as the day went on. Impressive low end torque, easy first kick starts every time, stable at speed, kinda slow turning for its small size, and super sturdy! Crashed it a few times and it did not miss a beat. I did get beat by guys on Yamaha TTR 125's and Kawasaki 140's, but it had enough fight in it for me to have a barrel of fun anyway!
Upgraded xr200? In the hands of a smaller stature adult, can be a bit of a vintage 4 stroke weapon in the tight tight woods of Michigan.
The whole XR lineup is just amazing tough as nails awesome bikes...easy to ride but very rewarding to those with offroad skills.
