Vehicle Information
BMW R80ST Motorcycle - Street (1982-1984)
The BMW R80ST, produced from 1982 to 1984, is an iconic street motorcycle, known for its balance and versatility. Powered by a 797.5 cc air-cooled, horizontally opposed Boxer twin engine, it delivered a reliable 50 horsepower. Designed as a more road-oriented version of the R80 G/S, the R80ST featured specific road-adapted characteristics, such as a 19-inch front wheel, shorter fork travel, road handlebars, a larger fuel tank, and a more comfortable seat.
During its production run from 1982 to 1984, the R80ST was offered as a single model and underwent very few modifications. Sources indicate that the 1983 and 1984 models were virtually identical to the previous year's, with no significant generation or engine changes. FAQ:
