Key specifications
Overview
Introducing the 1923 BMW R32, a pioneering naked bike that stands as a testament to the ingenuity of early motorcycle engineering. Launched during a time when the motorcycle world was ripe for innovation, the R32 represents BMW's first foray into motorcycle production, setting a benchmark for future models. With its distinctive design and robust performance capabilities, the R32 quickly carved a niche for itself among enthusiasts who appreciated both its aesthetic charm and its functional prowess. Today, it holds a revered place in motorcycle history as a symbol of the brand's longstanding commitment to excellence and performance. At the heart of the R32 lies a 494cc two-cylinder boxer engine, which delivers an unassuming yet respectable 8.57 horsepower at 3,200 RPM. This four-stroke powerplant provides a unique riding experience that is both smooth and responsive, perfectly complementing the bike's lightweight frame. Riders can expect a top speed of 95 km/h (59 mph), which, while modest by modern standards, was impressive for its time. The bike’s 3-speed gearbox and shaft drive (cardan) system facilitate seamless power delivery, allowing for a comfortable and engaging ride. Coupled with a fuel consumption of just 3.00 litres per 100 km, the R32 offers delightful efficiency, making it a practical choice for both leisure rides and everyday use. The R32's engineering brilliance extends beyond its engine. The bike features a sturdy steel double cradle frame that provides excellent stability and handling, complemented by a leading link front suspension that enhances ride comfort. The drum brakes on both front and rear, while archaic by today’s standards, were cutting-edge at the time, ensuring reliable stopping power. With a fuel capacity of 14 litres, riders can embark on longer journeys without frequent refueling stops. The kick starter adds a nostalgic touch, reminding riders of the mechanical simplicity that characterized early motorcycles. The R32 is not just a bike; it’s a piece of history that merges classic design with practical functionality. **
