1948 Was the very first year Harley Davidson built the little bikes. This is the first manufacturing design with a hand clutch and foot shift. It has a 2 cycle motor, single cylinder, 3 HP. The front forks is a girder front end with elastic band suspension. Factory ranked high speed of 50 MPH, I have never ever ridden it quicker than 20 MPH. There is a short in the headlight wiring.
