500 RS & S5C - 1935

Birth of industrial design

The arrival in 1934 of the unit-constructed Motobécane S was intended to correct the

faults of the unit-constructed "B" machine launched in 1930: dubious oil-tightness, hit-and-miss lubrication and outdated styling.

Successful Career

It reached its target, and the S range of 250, 350 and 500cc bikes with either overhead- or side-valves enjoyed a steady career during an uncertain period for the motorcycle.

Styled by Géo Ham

Launched just after new designs from Peugeot and Chaise, the B suffered from its old-fashioned appearance. Conscious of this handicap, the management took the uncommon step of calling in an industrial designer – famed motoring artist Géo Ham, who cleaned up the functional creation of the engineers and gave it style. The result was a clean, sleek bike with much-improved oil-tightness due to a rotary pressure-release valve driven off the magneto gearing. The cycle part – number plate, illuminated license plate, tank trim, knee-grips and muffler – benefited from Ham's talents, and the aesthetic result was favorably received by the market. Launched in 1934 as a three-speeder, the S unit initially powered seven models: the 350 and 500 side-valve "Grand Tourisme," the ohv 250, 350 and 500cc "Grand Luxe," and the 350 and 500cc "Grand Sport" with four overhead-valves; the only models with a foot-shift. A year later came a four-speed with a selector-pedal, standard on the ohv 500cc S5C and optional across the line, which gained a side-valve 250 but lost its ohv 250.
