### The 1961 BMW R50 2: A Timeless Classic The 1961 BMW R50 2 stands as a remarkable tribute to the engineering legacy of the Bavarian motorcycle manufacturer. Positioned in the allround category, this bike effortlessly blends performance with practicality, making it a desirable choice for both seasoned riders and collectors looking for a piece of motorcycling history. The R50 2 is a continuation of BMW's passion for producing reliable, stylish, and robust machines, capturing the spirit of the 1960s while remaining relevant in today’s vintage motorcycle scene. At the heart of the R50 2 is a 494 cc air-cooled, two-cylinder boxer engine that delivers an impressive 25.97 horsepower at 5800 RPM. This engine configuration is not only iconic but also offers a balanced weight distribution, enhancing stability and handling. Riders will appreciate the smooth power delivery and the confidence-inspiring acceleration that propels the bike to a top speed of 140 km/h (87 mph). With a compression ratio of 7.5:1 and a 4-speed gearbox, the R50 2 provides a thrilling ride experience, whether cruising along winding roads or navigating through city traffic. Moreover, with a fuel consumption of just 5.10 liters per 100 kilometers, this bike combines performance with economy, allowing riders to enjoy longer journeys without frequent fuel stops. The R50 2 is equipped with a steel double cradle frame that ensures durability while maintaining a lightweight design. Its suspension system features a cartridge front suspension and twin-shock swingarm at the rear, providing a comfortable ride over various terrains. The drum brakes at both the front and rear, with a diameter of 200 mm, deliver solid stopping power, ensuring safety and reliability. Additional features such as a kick starter and a 17-liter fuel tank further enhance the motorcycle’s practicality, making it ideal for long-distance rides or weekend adventures. ####
