The same year BMW stopped producing their successful R 50, they started building its more gritty sibling, the 1960 BMW R 50S. This machine has had its engine revised, and claimed a maximum power output of 35 horsepower at 5800 rpm, as opposed to the 26 horsepower produced by the base model. In all other departments, it remained virtually the same, boasting the same standard features such as the telescopic front fork, a rear suspension composed of a long swinging arm with suspension units and oil pressure shock absorbers, a drum braking system, a single seat, laced wheels, a large headlamp, full fenders, and mid-mounted foot pegs.
