Overview

### Discover the Classic Charm of the 1948 BMW R24 The 1948 BMW R24 stands as a testament to post-war ingenuity and the spirit of motorcycling. Positioned within the allround category, this classic bike was designed to offer a blend of utility and style, appealing to a diverse range of riders. With its elegant lines and timeless design, the R24 captures the essence of mid-20th century motorcycling, making it a sought-after piece for collectors and enthusiasts alike. As one of BMW's early ventures into motorcycle production after World War II, the R24 laid the groundwork for the brand’s storied legacy in the motorcycle industry. At the heart of the R24 is a robust single-cylinder, four-stroke engine with a displacement of 247 cc. Delivering a spirited 11.96 horsepower at 5,400 RPM, this powerplant enables the bike to reach a top speed of 95 km/h (59 mph). The engine's 6.8:1 compression ratio, coupled with a Bing carburettor, ensures smooth power delivery and exceptional fuel efficiency, achieving an impressive consumption rate of just 3.50 litres per 100 km (67.21 mpg). The lightweight frame, weighing in at a mere 130 kg (286.6 lbs), adds to the overall agility of the motorcycle, allowing riders to navigate urban streets and winding roads with ease. The 4-speed gearbox and dependable shaft drive system contribute to a seamless riding experience that’s both responsive and enjoyable. The R24 is equipped with practical features that enhance its riding experience, including a kick starter for reliable ignition and a steel-single cradle frame that provides stability and strength. The drum brakes, with a 160 mm diameter at the front and 180 mm at the rear, offer adequate stopping power for a bike of its era. The cartridge front suspension and rigid rear provide a balanced ride, capable of handling the roads of the time with confidence. The seat height of 710 mm makes it accessible for riders of various sizes, further expanding its appeal. With a fuel tank capacity of 12 litres, the R24 ensures that riders can embark on longer journeys without frequent stops, embodying the adventurous spirit of motorcycling. ###
