we bought a 200MXC for my son and that thing flippen RIPS.
I have been riding a DRZ400E for the past couple years, weight in at 240 before gear, and it hauls me around without ANY problems.
in fact, i just switched the rear sprocket from the stock 48 to a 44 as first gear was totally useless, even for my weight. no matter how steep the hill was, I could start out in 2nd without any thought at all.
dropping to a 44 really helped take some of the bite out of it and it'll still wheelie in 6th gear!!!
ktm's 200 is unbelievable.
