Overview

Introducing the 1957 BMW R50, a quintessential motorcycle that embodies the spirit of mid-20th century engineering excellence. Positioned as an allrounder, this iconic model from BMW combines classic design with remarkable functionality, appealing to both touring enthusiasts and city riders alike. With its distinctive two-cylinder boxer engine, the R50 not only showcases the manufacturer's heritage but also stands as a testament to an era when motorcycles were designed to deliver a thrilling riding experience without compromising on comfort. At the heart of the R50 lies a robust 494cc four-stroke engine that produces 25.97 horsepower at 5,800 RPM, delivering a top speed of 140 km/h (87 mph). This powerplant is known for its exceptional low-end torque and smooth acceleration, making it a joy to ride through winding roads and open highways alike. The bike's 4-speed gearbox, coupled with a shaft drive, provides seamless power delivery and a comfortable ride, while the fuel consumption of just 4.10 liters per 100 km (approximately 57.37 mpg) ensures you can enjoy longer journeys without frequent stops at the pump. The R50 is a true embodiment of the phrase "ride more, worry less." The engineering prowess of the R50 is evident in its thoughtful design and robust features. The steel double loop tubular frame not only enhances stability but also contributes to the motorcycle's classic aesthetics. Equipped with drum brakes on both the front and rear, the R50 ensures reliable stopping power, while the cartridge front suspension and twin-shock rear suspension offer a balanced ride quality that absorbs the bumps of the road. Add to this the iconic kickstarter, and you've got a motorcycle that feels as genuine as it does exhilarating to ride. ###
