Introducing the 1960 BMW R27, a classic motorcycle that elegantly encapsulates the spirit of post-war German engineering. Positioned as an allrounder, the R27 appeals to a diverse range of riders—from urban commuters to weekend enthusiasts seeking a bike that marries performance with practicality.

With its sleek lines and robust build, the R27 is not only a testament to BMW's storied heritage but also a delightful ride that continues to capture the hearts of vintage motorcycle aficionados. At the heart of the R27 lies a spirited 247cc single-cylinder, four-stroke engine that produces a respectable 17.95 horsepower at 7400 RPM. This engine, with its 8.2:1 compression ratio, delivers a surprisingly peppy ride, allowing the bike to reach a top speed of 130 km/h (80.8 mph). The air-cooled, carbureted setup ensures a reliable performance with a commendable fuel consumption rate of just 3.90 liters per 100 km, making it an economical choice for daily riding. The 4-speed gearbox, paired with a shaft drive system, offers smooth power delivery and a satisfying riding experience, whether navigating city streets or cruising along open highways. The R27 is equipped with features that exemplify BMW's commitment to rider comfort and safety. Its steel twin-loop frame provides a sturdy foundation, while the cartridge front suspension and twin-shock swingarm at the rear ensure a comfortable ride over various terrains. The expanding drum brakes, both front and rear, are reliable, offering ample stopping power with a diameter of 160 mm for each. Weighing in at 162 kg (357.1 lbs), the R27 strikes a balance between manageable weight and stability, enabling confident handling for riders of all skill levels.
