Overview

The 1961 Harley-Davidson FLH Duo Glide stands as a definitive representation of American touring motorcycles during the golden age of the open road. Launched amidst the post-war boom of the 1960s, the FLH Duo Glide was positioned as a luxurious touring option, captivating riders with its combination of comfort, style, and power. This motorcycle not only embodied the spirit of freedom and adventure but also served as a testament to Harley-Davidson’s commitment to engineering excellence and rider satisfaction. With its classic lines and chrome accents, the FLH Duo Glide continues to be a beloved icon among vintage motorcycle enthusiasts and collectors alike. At the heart of the FLH Duo Glide lies a robust 1212.72 ccm V2, four-stroke engine, delivering a commendable 55 horsepower at 7200 RPM. This powerful engine, coupled with its 4-speed gearbox and chain final drive, allows the bike to reach a top speed of 160 km/h (99.4 mph). The 7.0:1 compression ratio ensures a blend of torque and responsiveness, making it equally adept at cruising down highways or tackling winding back roads. Riders will appreciate the smooth power delivery and the unmistakable growl of the air-cooled engine, which not only enhances the riding experience but also pays homage to the unmistakable Harley-Davidson heritage. The FLH Duo Glide is loaded with features that enhance both comfort and performance. Its tubular cradle frame provides a solid foundation, while the hydraulic telescopic forks and swingarm rear suspension equipped with dual coil-over shocks offer a ride that is both stable and comfortable over long distances. The expanding drum brakes at both ends deliver reliable stopping power, a crucial feature for those long rides. Additionally, the inclusion of a kick starter and a windscreen not only adds practicality but also accentuates the bike’s touring capabilities, making it a well-rounded companion for any journey. In summary, the 1961 Harley-Davidson FLH Duo Glide is not just a motorcycle; it’s a piece of history that continues to inspire and excite riders. With its unique blend of vintage charm, enduring performance, and touring capabilities, this motorcycle remains a cherished icon among the Harley-Davidson lineup.

Pros

  • Comfortable Ride: The combination of hydraulic telescopic front forks and rear dual coil-over shocks ensures a smooth and enjoyable ride over various terrains.
  • Classic Aesthetic: The vintage design, complete with chrome accents, captures the essence of 1960s American motorcycling, making it a standout on the road.
  • Reliable Power: The V2 engine delivers ample power and torque, providing an exhilarating riding experience while maintaining a strong connection to Harley-Davidson’s legacy.

Cons

  • Weight: At 304 kg (670.2 pounds), the FLH Duo Glide can feel cumbersome for newer riders or during low-speed maneuvers.
  • Drum Brakes: While reliable, the expanding drum brakes may not offer the stopping power or response time that modern riders expect from contemporary motorcycles.
  • Kick Start Only: The absence of an electric starter can be a drawback for those accustomed to the convenience of modern bikes, making it less user-friendly for quick starts.
