Overview

Introducing the 1950 BMW R24, a classic icon in the all-round motorcycle category that captures the essence of post-war German engineering. As BMW's first foray into the era of civilian motorcycling after World War II, the R24 was designed to be a versatile machine, appealing to both everyday riders and enthusiasts alike. With its unique blend of functionality and charm, this motorcycle carved out a niche in the burgeoning motorcycle market of the early 1950s, offering a reliable and efficient ride that laid the groundwork for future BMW models. At the heart of the R24 lies a robust 247cc single-cylinder, four-stroke engine, producing a respectable 11.96 horsepower at 5,400 RPM. This powerplant is complemented by a 4-speed gearbox and a shaft drive system, allowing for smooth power delivery and a top speed of 95 km/h (59 mph). The motorcycle's lightweight build—tipping the scales at just 130 kg (286.6 lbs)—combined with a relatively low seat height of 710 mm (28 inches), makes it a nimble and approachable ride. Riders will appreciate the efficient fuel consumption of 3.50 litres per 100 km (67.21 mpg), making the R24 not just a classic, but also a practical option for those who value economy and reliability. The R24 boasts several key features that underscore its quality and engineering prowess. Its steel single cradle frame offers robust support while maintaining a lightweight profile, and the suspension setup—featuring a cartridge front and rigid rear—ensures a balanced ride. The drum brakes, with a 160 mm front diameter and a 180 mm rear diameter, provide adequate stopping power for its era. Additionally, the air-cooled engine and Bing carburettor showcase BMW's commitment to simplicity and reliability, allowing riders to enjoy the open road without the worry of complex systems. **

Pros

  • Timeless Design: With its classic lines and aesthetic appeal, the R24 is a head-turner for motorcycle enthusiasts and collectors alike.
  • Fuel Efficiency: Its impressive fuel consumption allows for extended rides without frequent stops at the pump, making it an excellent choice for touring.
  • Lightweight and Nimble: The low weight and manageable seat height make it accessible for a wide range of riders, promoting confidence and control.

Cons

  • Limited Power Output: While sufficient for leisurely rides, the 11.96 HP engine may feel underpowered for those seeking a more exhilarating experience.
  • Basic Suspension: The rigid rear suspension may not provide the level of comfort and handling that modern riders expect on longer journeys.
  • Drum Brakes: While adequate for the era, the drum braking system may lack the responsiveness and performance of contemporary disc brakes, particularly on downhill descents or in emergency situations.
