Yes it was a 1974 Honda CR250M. Not long ago I did take it to some tracks... the looks I would get... priceless. The only time I would entertain the jumps was if it was a log tabletop, or a rolling jump, although a track near me has a nice up-hill double that I used to clear. Other than that, I wasn't one for the jumps.
Not long before I sold it, I had it at the track, and I let my son's friends take it for a spin. One's a "B" rider, and the other 2 are pretty good "C" riders. I asked them to take it slow for a few laps to get used to the old girl, then let her rip. They all had the biggest grins on their faces. They couldn't believe the power the bike had, but also the lack of suspension, and brakes (drum not disk). They wanted to slip that engine into a modern bike with "real" suspension and brakes.
After riding her they now understood how I could blow by them on the flatter, non rutted, sections, and how I could dominate them on the up-hills. they also understood why I they would catch and pass me in the ruff sections, on the long down-hills, in the jump and rhythm sections. Hey no suspension, and lack of brakes, and besides, I'm old and it takes longer to heal... (not to mention an old fat guy going over the handlebars is not a pretty site.)
After riding a modern bike, I realized what I was missing. I don't hurt as much the day after a long ride. After all those years on the vintage bike, I'm not one for major air. I still prefer keeping at least on wheel on the ground....
