In 1977, BMW launched the R 80/7 motorcycle, which had a larger displacement and was a successor to the R 75/7 model. Compared to its predecessor, the R 80/7 achieved a displacement increase with a larger bore and kept the same stroke.

The 797cc flat-twin engine that powered the 1977 BMW R 80/7 model with an output power of 50 hp at 7,250 rpm and 58 Nm (43lb-ft) of torque at 4,000 rpm sent the bike to a top speed of 170 kph (104 mph).

Due to the 1976 reorganization of insurance classes for motorcycles from displacement to horsepower, BMW had two versions of the model, one with a more favorable 50 hp for insurance purposes and the more powerful S version with an output of 55 hp reserved for authorities and export.

After the R 60/7 model was discontinued in 1979, the R 80/7 replaced it and assumed the role of a mid-range motorcycle in the BMW product range. Until production ended in 1984, the R 80/7 motorcycle received a bunch of upgrades and modifications. The most striking modifications brought upon the bike in its lifetime were the twin disc brakes on the front wheel introduced in 1978, the modern cast alloy rims, and the sportier S-shaped bench seat in 1979.
