I have had a few two strokes when I was in my 20's a Yamaha RD 350 f2 ypvs , in black and red, that was fast and handled pretty well, 5 months later I got rid and bought a Stan Stevens tuned RD 500 powervalve, with a full allspeed system on it. It's sound was intoxicating, along with the smell and 20 miles per gallon fuel range. Wish I kept that, it was a less popular red and black one. In 2000 I bought a 1972 suzuki T250 hustler, that thing terrified me. I had a tuned 1200 Suzuki bandit at the time, and it was sedate compared. Crap brakes didn't do corners and no engine breaking. Marvellous.
