oh, wheelies......if you know how to balance your weight, controll your throttle and braking right, you can pull off some insane-looking wheelies. ive kept my 125 up for quite a long ways, but like youve heard, its hard, and dangerous. its not so much the size of the bike, but how your situated on it, how and when you dump the clutch and how and when you pop down and pull up on the bars. but. if youve rode, you know what im talking about. the worst thing about wheelies are the unexpected ones, i was riding my 250, its a bit older, but a little faster too, on an open dirt field, i was in the throttle hard, throwing dirt straight up when the nobby got caught on a rock, a big one just under the surface of the dirt, the bike reared up and i bailed, landing on my knees an the bike went right side down, broke the clutch cover one another rock nearby and i got to push the bike 3 miles home, i was not happy........the point is, anything will come up into a wheelie, you gotta be carefull with that.
