Unveiled on February 14, 1935, at the German Automobile Exhibition in Berlin, the BMW R12 made its debut alongside the R17, establishing itself as the direct successor to the esteemed BMW R11. This motorcycle embodies a rich legacy, blending timeless design with enduring performance, and its battle-tested appearance narrates a story of enduring strength and reliability.
Debuting alongside the R17, the BMW R12 marked a historic milestone as one of the world's pioneering motorcycles equipped with hydraulically damped telescopic forks. By the year 1942, a total of 36,000 BMW R12 motorcycles had rolled off the production line. The powerhouse at the heart of this iconic machine was the M 56 S 6 or 212 engine, featuring a twin-cylinder boxer configuration, a four-stroke system, and a distinctive flathead design. This engine not only contributed to the bike's performance but also played a significant role in shaping the technological advancements within the motorcycle industry.
The BMW R12, equipped with two carburetors, featured a battery and coil ignition system. In contrast, R12 variants with a single carburetor employed a magneto ignition, capable of operating independently from the battery. Powering through with technological diversity, the BMW R12 boasted a four-speed manual gearbox, manipulated by a hand shift lever conveniently positioned on the right side of the fuel tank. Production showcased several nuanced variations in detailing.
True to the BMW Motorcycles tradition, the final drive employed a shaft mechanism, with the drive shaft positioned on the right side of the motorcycle. The front suspension was characterized by a telescopic fork, while the frame remained rigid, featuring an un-sprung rear end supporting the final drive and a rider-friendly sprung seat. Drum brakes adorned both the front and rear wheels of the R12, contributing to its robust braking system. Notably, many R12 motorcycles were equipped with a sidecar affixed to the right side, enhancing the versatility and utility of this iconic machine.
