1936-37: Innovations by engineer Schleicher

The R 5 is a completely new design by Rudolf Schleicher. With 24 bhp and 500 ccm, it is one of the sportiest motorcycles of the times. The R 5 has an engine with a tunnel housing, two camshafts, a gearbox with pedal shift, a tube frame made of seamlessly drawn and electrically welded conic oval tubes, adjustable damping at the telescopic fork and footrests instead of the step plates which had been commonly used up to that time.
