Overview

Introducing the 1958 BMW R50, a classic motorcycle that firmly established BMW's reputation in the allround category. With its striking design and robust engineering, the R50 appealed to a wide range of riders—from the everyday commuter to the avid touring enthusiast. This vintage machine embodies the spirit of the late 1950s, offering a blend of performance, reliability, and advanced technology for its time. As a member of BMW's iconic boxer series, the R50 not only turned heads with its unique style but also set the standard for quality and craftsmanship that the brand is known for today. At the heart of the R50 lies a powerful 494cc two-cylinder boxer engine that delivers a respectable 25.97 horsepower at 5800 RPM. This four-stroke powerhouse is designed with a 6.8:1 compression ratio and a bore and stroke of 68mm, which provides a balanced mix of torque and responsiveness. Riders can enjoy a top speed of 140 km/h (87 mph), making it an exhilarating ride on both city streets and open highways. The air-cooled engine is paired with a smooth 4-speed gearbox and a reliable shaft drive, allowing for seamless power delivery and a more comfortable riding experience. Coupled with an impressive fuel consumption rate of 4.10 liters per 100 km, the R50 is not just about performance; it’s also a practical option for long-distance journeys. The R50's engineering excellence is evident in its robust steel double loop tubular frame, providing stability and durability for a ride that remains true to its heritage. The motorcycle features drum brakes at both the front and rear, ensuring effective stopping power while maintaining the classic aesthetic. The front suspension utilizes a cartridge design, while the rear features twin-shock swingarm suspension—both contributing to a smooth and predictable ride. Additional features like the kick starter evoke nostalgia and remind riders of a time when simplicity and mechanical charm were king. Whether you're cruising along scenic routes or navigating urban environments, the R50 promises a captivating ride that pays homage to motorcycle history. **

Pros

  • Timeless Design: The R50’s classic aesthetics and BMW’s iconic boxer engine layout make it a head-turner on the road.
  • Smooth Performance: With a balanced power delivery and a comfortable riding experience, it is ideal for both long-distance touring and daily commutes.
  • Fuel Efficiency: Exceptional fuel consumption of 57.37 MPG ensures that you can enjoy longer rides without frequent stops at the gas station.

Cons

  • Limited Power: While sufficient for cruising, the 25.97 HP may feel underwhelming for riders seeking high-performance thrills.
  • Drum Brakes: The drum brake system, while effective for its time, may not provide the stopping power and responsiveness expected by modern riders.
  • Kick Start Only: The absence of an electric starter means that riders must be prepared to kick-start their bike, which may not appeal to everyone, especially those accustomed to modern conveniences.
