The BMW R12 and R17 are flat-twin engine motorcycles made by BMW Motorrad from 1935 through 1942. They were developed in 1935 based on the R7 concept of 1934.

In 1930 BMW broke fresh ground with the launch of the pressed-steel-framed R11, and followed that up in 1935 with the introduction of a hydraulically-damped telescopic front fork on the R12, the first time such a device had been seen on a mass-produced motorcycle.
Also notable as the first BMW motorcycle to have a four-speed gearbox, the R12 was a huge success with approximately 36.000 produced up to 1938, and was used by the Wehrmacht in the war’s early years before the introduction of the purpose-built military R75.
