Overview
Introducing the 1938 BMW R23: A Classic Allrounder The 1938 BMW R23 stands as a beacon of engineering prowess from a time when the world was on the brink of change. Nestled in the allround category, this motorcycle was designed for both the everyday rider and the enthusiast seeking adventure. With its sleek lines and distinctive BMW styling, the R23 not only exudes charm but also embodies the spirit of pre-war motorcycling. As one of the last models produced before World War II, it represents a pivotal moment in BMW's storied history, bridging the gap between tradition and modernity. Engine Performance and Riding Characteristics At the heart of the R23 is a robust 247cc single-cylinder, four-stroke engine that produces a respectable 10.06 horsepower at 5,400 RPM. This power output may seem modest by today’s standards, but it delivers a delightful riding experience, allowing the R23 to reach a top speed of 95 km/h (59 mph). The engine's 6.1:1 compression ratio and balanced bore-stroke ratio of 68 mm by 68 mm contribute to a smooth and responsive throttle that is perfect for both city commuting and leisurely weekend rides. The 3-speed gearbox, paired with a reliable shaft drive, ensures seamless power delivery and an uncomplicated riding experience, making it an ideal choice for both novice and seasoned riders looking for a nostalgic journey through history. Key Features and Technology The 1938 BMW R23 is not just about performance; it also boasts several engineering innovations that were ahead of its time. The sturdy steel-single cradle frame provides excellent stability, while the telescopic front fork enhances ride comfort and handling on varied terrains. The dual drum brakes—160 mm at the front and 180 mm at the rear—offer dependable stopping power, ensuring rider safety. Moreover, with a fuel capacity of 9.60 litres (2.54 gallons), this classic motorcycle allows for extended journeys without frequent stops. The kick starter adds a touch of retro charm, harking back to a simpler time when technology was straightforward yet effective. **
