Overview

Introducing the 1964 BMW R27, a classic motorcycle that embodies the spirit of post-war German engineering and design. Nestled within BMW's allround category, the R27 is not just a bike; it’s a statement of freedom and exploration. With its sleek lines and timeless aesthetic, this motorcycle appeals to both collectors and enthusiasts alike, offering a taste of vintage charm while delivering reliable performance on the road. Whether you're cruising through the countryside or navigating city streets, the R27 stands as a testament to BMW's commitment to quality and innovation. At the heart of the R27 lies a 247 cc single-cylinder, four-stroke engine that produces 17.95 horsepower at 7400 RPM. This power plant, paired with a 4-speed gearbox and a shaft drive, offers a smooth and engaging ride. With a top speed of 130 km/h (80.8 mph), the R27 provides an exhilarating experience while maintaining excellent fuel efficiency—boasting an impressive consumption rate of just 3.30 litres per 100 km (71.28 mpg). The bike’s compression ratio of 8.2:1, combined with its air-cooled system and Bing carburettor, ensures reliable performance while allowing riders to enjoy a responsive throttle and a satisfying engine note. The R27 is equipped with features that enhance both safety and comfort. Its steel twin-loop frame provides a sturdy foundation for the bike, while the twin-shock swingarm rear suspension ensures a smooth ride, even on uneven terrains. The front and rear drum brakes, each measuring 160 mm in diameter, offer reliable stopping power, giving riders confidence in their braking performance. Additionally, with a fuel capacity of 15 liters, the R27 allows for extended journeys without frequent stops, making it an ideal companion for long rides. The classic kick starter adds a nostalgic touch, harkening back to an era when the thrill of starting a bike was an event in itself. **

Pros

  • Classic Styling: The R27's vintage design turns heads and evokes admiration from fellow riders and onlookers alike.
  • Fuel Efficiency: With a consumption rate of 71.28 mpg, this motorcycle is economical, allowing for longer rides without frequent refueling.
  • Smooth Handling: The combination of its lightweight frame and well-engineered suspension delivers a comfortable and responsive riding experience.

Cons

  • Limited Power: While the engine provides adequate performance for leisurely rides, it may feel underpowered for those seeking high-speed thrills.
  • Drum Brakes: The traditional drum braking system, while reliable, lacks the stopping power and responsiveness of modern disc brakes.
  • Kick Start Only: The absence of an electric start may deter some riders who prefer the convenience of modern systems, making it less accessible for new riders.
