The side-valve 736 cc BMW R12 was first displayed at the Berlin Motor Show in February 1935. Based on the earlier R11, the R12 benefited from two major improvements – a new four-speed gearbox and, most importantly, Rudolf Schleicher’s oil-damped telescopic front fork. This revolutionary feature first appeared on Alfred Böning’s R7 prototype of 1934 and is notable as the first hydraulically damped telescopic fork fitted to a production motorcycle.

The R12’s engine was an evolution of the R11, but featured a stronger crankshaft. It produced 18 hp at 3,400 rpm with a single carburetor or 20 hp at 4,000 rpm with twin carburetors. The gearbox retained the traditional hand change, which was operated through a gate on the right side. At the rear, a drum brake was fitted, allowing BMW to fit interchangeable 19" wheels for the first time. For 1936, the R12 received sweeping Art Deco-style mudguards, which helped further disguise the heavy pressed-steel frame.

The R12 was a curious combination of old and new, retaining a rigid rear end at a time when many other manufacturers had adopted rear suspension. Nevertheless, more than 36,000 examples were built between 1935 and 1942, making it the most popular BMW motorcycle of its era.

Built in April 1940, this BMW R12 displays matching numbers on its frame, engine, and data tag and is finished in classic Avus Black with white pinstriping. Restored under previous ownership, the BMW has spent the last decade in a private California-based collection surrounded by other noteworthy examples of industrial design. An outstanding example of a landmark motorcycle, this R12 would be a fantastic addition to any motorcycle collection or a perfect display among a stable of BMW automobiles.
