Overview

### Introducing the 1924 BMW R32: A Timeless Classic The 1924 BMW R32 stands as a pivotal model in the history of motorcycling, marking BMW's foray into the world of two-wheeled engineering excellence. Positioned in the naked bike category, the R32 was not only the first motorcycle to bear the iconic BMW badge but also a showcase of innovative engineering for its time. With its robust design and pioneering technology, it laid the foundation for BMW’s future motorcycle lineage, capturing the spirit of freedom and adventure that resonates with riders even today. ### Engine Performance & Riding Experience At the heart of the R32 lies a formidable 494cc two-cylinder boxer engine, a configuration that has since become synonymous with BMW motorcycles. Producing 8.57 horsepower at 3,200 RPM, this four-stroke engine delivers a straightforward and reliable performance, allowing the R32 to reach a respectable top speed of 95 km/h (59 mph). The unique design of the boxer engine not only contributes to a low center of gravity, enhancing stability, but also provides a delightful thrum that reverberates through the chassis. Coupled with a 3-speed gearbox and a shaft drive system, the ride is smooth and effortless, making it an excellent choice for leisurely journeys through the countryside or spirited rides around town. ### Innovation and Features The R32 is packed with features that were groundbreaking at the time, such as its air-cooled engine and magneto ignition system, which ensured reliable starts and consistent performance. The bike boasts a sturdy steel double cradle frame, paired with a leading link front suspension that offers commendable handling and comfort. The drum brakes, measuring 150 mm in diameter both front and rear, provide adequate stopping power, ensuring safe navigation through the winding roads. With a fuel capacity of 14 liters and an impressive fuel consumption of just 3.00 liters per 100 km, this motorcycle offers an excellent range, allowing riders to experience the open road without frequent stops. ###
