I remember reading popular mech. magizine when I was a kid ( mid 70's ) and seeing the bike bug engines and some others. I always wanted one, But never did get one. Got old enough to drive cars and motorcycles, and soon any thoughts about bikes were gone.
Wasn't cool to ride a bike unless it was a KZ-900. Then Last year I was watching a tv show about Green stuff like bio diesel and such, Then they showed a bike called the derringer from a shop in L.A., It was a board trac racer look alike with a Happy-Times kit installed. I then had to have one, and the rest is history...
