Overview

Introducing the 1928 BMW R52: A Timeless Classic in the Allround Category The 1928 BMW R52 stands as a testament to the pioneering spirit of early motorcycle craftsmanship. Nestled in the heart of the allround category, this elegant machine captures the essence of an era where engineering met art. With its distinctive two-cylinder boxer engine and iconic design, the R52 not only served as a reliable mode of transportation but also marked BMW’s early foray into the motorcycle market, setting the stage for decades of innovation. Offering a harmonious blend of form and function, the R52 remains a coveted classic among motorcycle enthusiasts and collectors alike. Engine Performance and Riding Characteristics: The Heart of the R52 At the core of the R52 lies a robust 486cc two-cylinder boxer engine, delivering a respectable 11.96 horsepower at 3,400 RPM. This four-stroke powerhouse, with a compression ratio of 5.1:1, propels the motorcycle to a top speed of 100 km/h (62.1 mph). The air-cooled engine, combined with a 22mm BMW Spezial carburettor and magneto ignition, ensures smooth performance and reliable starts. Riders will appreciate the torque-rich delivery that makes urban commuting as enjoyable as leisurely countryside rides. Coupled with a 3-speed gearbox and a silky-smooth shaft drive, the R52 offers an engaging riding experience that harkens back to the golden age of motorcycling. Key Features and Innovative Technology of the R52 The R52 is not merely about engine performance; it boasts an array of features that enhance both safety and comfort. The steel double cradle frame provides a solid foundation while the leading-link front suspension ensures stability and a smooth ride over varying terrains. The 200 mm drum brakes offer effective stopping power, a critical feature for the era. Weighing in at 152 kg (335 pounds) with fluids, the R52 strikes a balance between agility and durability, making it a nimble companion for both new riders and seasoned veterans. With a generous fuel capacity of 12.50 litres (3.30 gallons) and a frugal fuel consumption rate of 3.50 litres/100 km (67.21 mpg), this vintage beauty allows for extended journeys without frequent stops. **
