1934 Harley Davidson CB single cylinder 30.50” (500cc). According to my internet research, this is a very rare bike. The CB was offered for one year only. It utilized the frame from Harley’s 350cc “B” model and the engine from the 500cc “C” model. According to my search, only 310 “CB” models were built. The powdercoat / paint on the frame, wheels, front-end and handlebars are quite nice.
