The R12 was an evolution of the R11 – in the process it gained telescopic forks, a 4-speed transmission, and a little bit of cosmetic work. This actually made the R12 (and the sportier R17) the first production motorcycles with hydraulically damped telescopic forks.

The BMW R12 with two carburetors used a battery and coil ignition, while R12s with a single carburetor used a magneto ignition, capable of working independently from the battery.The BMW R12 had a four-speed manual gearbox, operated by a hand shift lever on the fuel tank’s right side.
