My first bike was a 1948 Harley Model S, the predecessor to this model. It was a 125 cc two stroker, rigid rear and rubber-band suspension front. Made about 6 Hp on a good day. Sold it to a guy who forgot that with a two stroke, going down a long steep hill, you have to feed some fuel/oil mix occasionally to keep the piston and internals lubed. He didn't. The whole affair siezed and self destructed. He survived; the bike did not.
