My son and I went to a Honda dirtbike school in Ohio 16? years ago. There were 125’s and 200’s provided. My son at 13 or 14? got a 125 and I got a 200. I hadn’t ridden a dirt bike in 40+ years but I was thrashing the 200 by midday. It was very rideable and reminded me of my SL from 1970 with more power and a lot more suspension. I left the school thinking that a 250 would be appropriate for me, and my son would be up to a 250 in time. Junior did not have any motorcycling experience coming in but was doing very well on the 125 by the end of the day.
On the drive home we were passed by a group of sport bikers. A Gixxer rider approached us on his rear wheel and passed us at 80+ mph. He tooled down the exit ramp and carried his wheelie around the bends to the stop sign at the end of the ramp. Junior got an eyeful of that, oops, wrong lesson for the day.
