I saw one of these when I was 12 years old, and I said to myself,,, "self" one day I'm going to have one of these! I hate to disapoint myself so I guess it was in 1986 I met this guy who's dad had one, a 1964, the first year for rokon. The new models are much better,they have disk brakes (that really work) quiet torkey 4 stroke engines, the transmissions are much better, I see that they have a street legal model and electric start and front suspension. Yah, mine had no suspension, a stinky chrysler westbend 2 stroke engine, and really no brakes at all. Top speed was about 25, but on a ruff trail it felt more like 65, at speeds under 10 it was hilarous, anything above say, 20 you were taking your life in your hands,you could get yourself pounded with no warning whatsoever.
