Overview

Introducing the 1968 BMW R50US, a timeless classic that embodies the spirit of post-war motorcycling in the late 1960s. Nestled within the allround category, the R50US was designed for versatility, appealing to both the casual rider seeking leisurely weekend excursions and the dedicated enthusiast craving a reliable companion for long-distance journeys. With its unmistakable boxer engine configuration and iconic styling, this motorcycle stands as a symbol of BMW's commitment to quality and performance, making it a coveted piece among vintage motorcycle collectors and aficionados alike. At the heart of the R50US is its robust 494cc two-cylinder boxer engine, a powerplant that combines both heritage and innovation. Producing 25.97 horsepower at 5800 RPM, the R50US delivers a smooth and engaging riding experience, with a top speed of 140 km/h (87 mph) that is both exhilarating and manageable for its era. The bike’s air-cooled engine features a compression ratio of 7.5:1, paired with a 4-speed gearbox and a reliable shaft drive system, ensuring a seamless transfer of power to the rear wheel. Riders will appreciate the bike’s balanced handling, aided by a well-engineered steel double cradle frame and twin-shock rear suspension, making it equally adept at navigating winding roads or cruising along the highway. The 1968 BMW R50US is not just about performance; it also boasts features that enhance its usability and rider comfort. The bike is equipped with a 17-liter fuel tank, providing ample range for extended rides, while the drum brakes, both front and rear, give the rider confidence in stopping power, despite their vintage design. The kick starter adds a nostalgic touch, reminding riders of a simpler time, while the classic BMW aesthetic—characterized by its elegant lines and chrome accents—turns heads wherever it goes. Whether you’re a fan of classic motorcycles or simply appreciate engineering excellence, the R50US offers a compelling blend of history and performance. **
