About BMW R61 1938

Introducing the 1938 BMW R61: A Timeless Classic

The 1938 BMW R61 stands as a testament to the pioneering spirit of motorcycle engineering in the late 1930s. Positioned as an all-rounder, this iconic machine captures the essence of versatility, combining performance with reliability. With its distinctive design and advanced technology for its time, the R61 not only appealed to casual riders but also attracted the attention of serious enthusiasts and touring aficionados. As one of BMW's early ventures into the realm of high-performance motorcycles, the R61 set the stage for the brand’s legacy of excellence.

At the heart of the R61 lies a robust 600cc two-cylinder boxer engine, delivering a respectable 17.95 HP at 4800 RPM. This four-stroke powerhouse, with its 5.7:1 compression ratio, provides a smooth yet exhilarating ride, reaching top speeds of 115 km/h (71.5 mph). The air-cooled engine, paired with an Amal carburettor, ensures a balanced blend of power and efficiency, achieving an impressive fuel consumption of 3.50 litres per 100 km (67.21 mpg). The 4-speed gearbox works seamlessly with the shaft drive, enhancing the riding experience by providing smooth gear transitions and a sense of stability, making the R61 an inviting option for both city commutes and longer journeys.

The engineering prowess of the 1938 R61 extends beyond its engine. The steel double cradle frame is complemented by a leading link front suspension and twin-shock swingarm rear suspension, ensuring a comfortable ride over varied terrains. With front and rear drum brakes, each measuring 200 mm in diameter, riders can confidently navigate through winding roads and urban landscapes alike. The classic aesthetic is further enhanced by a sleek design that measures 2,130 mm in length and 815 mm in width, embodying the elegance of its era while providing functionality. Notably, the kick starter adds an authentic touch to the riding experience, invoking nostalgia for the traditional motorcycle enthusiast.
