when i was a kid a friend got a Yamaha 125, i putted around a bit got the feel for it, then just jumped on it on the road, the front wheel was off the ground for 3 gears, i stopped in front of his house and just handed it back, here, this is no fun on the road. i was 225 lbs and had as much weight as i could over the bars and had a death grip with my legs to the tank.
then i got to ride a old school race bike, it was another yamaha but a road racer, had fork locks and a two stroke 550, that thing was a b1tch to drive slow, (cause the bars did not move more then a inch either way) but it hauled ass.
