About BMW R32 1925
The Classic Elegance of the 1925 BMW R32
The 1925 BMW R32 is a milestone in motorcycle history, representing the brand's entry into the world of powered two-wheelers. As a naked bike, it embraces simplicity and functionality, focusing on the raw pleasure of riding. With its clean lines and robust design, the R32 quickly carved out a niche for itself among enthusiasts and collectors alike. This motorcycle is not just a means of transportation; it’s a piece of art that encapsulates the spirit of its era while laying the groundwork for future BMW models.
At the heart of the R32 lies a remarkable 494cc two-cylinder boxer engine, later becoming a signature feature for the brand. Producing 8.57 horsepower at 3200 RPM, the engine may seem modest by today’s standards, but it delivers an exhilarating ride with a top speed of 95 km/h (59 mph). The balanced bore and stroke of 68mm each and a compression ratio of 5.1:1 create a smooth power delivery, making it a joy to ride through the winding roads of the early 20th century. With a three-speed gearbox and a shaft drive system, the R32 provides a uniquely engaging riding experience, allowing enthusiasts to appreciate the mechanical simplicity and reliability that define BMW's engineering philosophy.
The 1925 R32 features a steel double cradle frame, which provides a robust yet lightweight structure, weighing in at just 122 kg (269 pounds) when fully fueled. The front and rear drum brakes, each measuring 150mm, offer adequate stopping power for the time, while the leading link front suspension ensures stability and comfort over uneven surfaces. The 14-liter fuel tank affords riders a respectable range, further enhancing its practicality for both short jaunts and longer adventures. With its kickstarter and air-cooled engine, the R32 embodies the charm and reliability of early motorcycling technology, making it a favorite for vintage motorcycle enthusiasts.
