In 1976, at the International Bicycle and Motorcycle Show (IFMA) in Cologne, BMW launched the BMW R 100 S as a successor to the legendary R 90 S alongside the BMW R 100 RS. Compared to its predecessor, for the 100 S model, BMW reduced the engine output by two hp and made it available in a Silver Smoke or Daytona Orange finish.

The Dell’orto carburetors used by its predecessor were replaced by the Bing constant pressure carburetors, but despite its all sportiness, the model never achieved the glamor of its predecessor. In terms of sales figures, the R 100 S never matched the sales of the R 90 S.

The 1976 BMW R 100 S, powered by a 980cc flat-twin engine with a power output of 65 hp at 6,600 rpm and 76 Nm (56 lb-ft) of torque available at 6,000 rpm combined with a five-speed manual transmission and a curb weight of 220 kg (485 lbs) pushed the bike to a top speed of 200 kph (124 mph).

As standard fittings, the bike came with a dual seat, pillion grab rails, a small nose-fairing with a windshield, an analog instrumentation panel, 260 mm dual front disc brakes coupled to a 200 mm rear drum brake unit, die-cast aluminum wheels, a chromed dual exhaust system, and a center stand.
