BMW R4 Series 4

Introducing the 1935 BMW R4 Series 4, a quintessential representation of interwar motorcycle engineering that combines elegance with utilitarian performance. Positioned in the allround category, the R4 was designed to cater to the burgeoning demand for versatile motorcycles capable of both commuting and leisure riding. With BMW's hallmark attention to detail, this model established itself as a reliable companion for riders seeking both style and substance during a time when motorcycles were transitioning from simple two-wheelers to sophisticated machines. At the heart of the R4 Series 4 lies a robust 398cc single-cylinder, four-stroke engine that produces 14 horsepower at 4,000 RPM. This power output may seem modest by today’s standards, but it’s perfectly matched to the motorcycle's lightweight design, allowing it to reach a top speed of 95 km/h (59 mph). The air-cooled engine, paired with a dry single-plate clutch and shaft drive, ensures a smooth and responsive ride, while the impressive fuel efficiency of 3.50 litres per 100 km (approximately 67.21 mpg) makes it an economical choice for long-distance journeys. Riders can expect a comfortable cruising experience, thanks to the R4’s stable handling characteristics and its well-balanced chassis. The R4 Series 4 is not just about performance; it also boasts several key technological features that were innovative for its time. The pressed steel duplex frame provides a solid foundation, while the cartridge front suspension and rigid rear suspension contribute to a predictable ride. With a front and rear brake diameter of 180 mm, the expanding drum brakes deliver reliable stopping power, instilling confidence in riders navigating various terrains. The classic kick starter adds a nostalgic touch, inviting riders to engage with the motorcycle in a hands-on manner. All these features come together to create a motorcycle that is as enjoyable to ride as it is to admire. **
