Introducing the 1928 BMW R42: A Classic Allrounder

Step back in time to the late 1920s, when motorcycling was transforming into a thrilling mode of transportation, and meet the BMW R42. Launched in 1928, this iconic model signified a pivotal moment for BMW as it entered the motorcycle market with a robust and versatile design. Positioned as an allround motorcycle, the R42 was engineered to cater to a vast array of riders—from casual enthusiasts to those seeking spirited rides across the open road. Its classic styling, paired with BMW’s commitment to quality, quickly established the R42 as a respected choice among motorcyclists of the era.

At the heart of the R42 lies its impressive 494cc two-cylinder boxer engine, which delivers a respectable 11.96 horsepower at 3,400 RPM. This four-stroke powerhouse, with a balanced bore and stroke of 68mm, is renowned for its distinctive sound and character. Riders will appreciate the smooth power delivery and the capability to reach a top speed of 95 km/h (59 mph), making it suitable for both city commuting and weekend getaways. The 3-speed gearbox and shaft drive offer a reliable and engaging riding experience, while the air-cooled system ensures longevity even during extended journeys. The R42’s rigid rear suspension contributes to its vintage charm, providing a ride that feels connected to the road.

The BMW R42 is not just about raw power; it also boasts several features that highlight the ingenuity of its time. The steel double cradle frame ensures stability and durability, while the leading-link front suspension enhances cornering capabilities. The expanding drum brakes, with a diameter of 150 mm, offer sufficient stopping power, a necessity in an era when brakes were still evolving. Complemented by a kick starter, the R42 seamlessly blends simplicity with function, making it a reliable companion for any ride. Whether you're cruising through town or embarking on an adventure, the R42 stands as a testament to BMW's engineering prowess and commitment to rider satisfaction.
