At 15 I bought my first, a used 1976 RM125.
Binelli's!! My buddy a couple of those dirt bikes. Pretty junky quality but they were fun.
Among others, I had a used RM 250, `79 1/2; they had a swingarm change or something mid model year. I bought that around '84 I think.
Good bike but couldnt keep up with the mono shock boys on the whoop de doos.
Snapped the right footpeg clean off landing a jump, rapped my nuts hard on the tank on the way down, and the rest was a tumbling dance of man and machine for several yards.
After some soul searching staring up at the sky, (I thought I was paralyzed at first) I got up, not seriously injured. The handlebar and controls were pretty mangled up but workable. Rode it home fixed it up and thought a lot about what had happened.
Found a great deal on a new leftover '85 CR500!@! (last air cooled model was not in vogue).
Once I broke it in and opened it up on a gravel road, it was the only time I was truly scared (for a bit anyways) at the speed.
Didn't get to ride nearly enough as a young adult with responsibilities.
Missed it.
so I bought a .....
JET SKI !! - the real kind you stand up on.
Great fun, almost drowned jumping waves in the surf more than once.
Then somewhere along the way I got married, had kids and grew up I guess.
Wish I could have it both ways.
