This is the closest I could find to my *first* motorcycle. I had a later model, it had a more normal fork, rubber seat (still sprung) and the engine was a Sachs 4 speed 175cc 2 stroke job. I did have a moped before the delivery trike, but 50cc does not a motorcycle make.... unless it was a Kreidler. The 3 wheel delivery bike was made by Tempo in Norway (Jonas Øgeland) if my memory serves, and back then, 2 strokes were so common that there were gas pumps that pre-mixed the fuel with oil for you. I think the best thing about it was being able to stop and leave your feet on the pegs!
