BMW R 4 Series 1

The 1932 BMW R 4 Series 1 represents a significant step in motorcycle development during its time. Powered by a 398cc single-cylinder engine, it produced a modest 12 horsepower at 4000 RPM, enabling a top speed of 100 km/h. The engine character would have been very basic, providing adequate power for the riding conditions of the era. The 10-liter fuel tank ensured reasonable range for touring. Ergonomics on the R 4 would be typical for a motorcycle of the 1930s, with an upright riding position and a focus on simplicity. The friction shock absorber up front provided a basic level of suspension, while the expanding drum brake offered rudimentary stopping power. This setup would require a skilled rider to manage on varied road surfaces. The target rider for the BMW R 4 Series 1 was likely someone seeking reliable transportation rather than outright performance. Its simple design and manageable power delivery would appeal to those who valued practicality and ease of maintenance. This motorcycle embodies the early days of motorcycling, where the journey was as important as the destination.
