Overview

The 1963 Harley-Davidson FLH Duo Glide stands as a beacon of classic American touring motorcycles, embodying the spirit of freedom and adventure that the open road promises. This iconic machine was positioned at the premium end of Harley's lineup, targeting riders who craved a blend of comfort, style, and performance. With its robust design and distinctive aesthetic, the FLH Duo Glide appealed to both die-hard Harley enthusiasts and newcomers alike, marking a significant evolution in Harley's touring capabilities and setting the stage for future models. At the heart of the FLH Duo Glide lies a powerful 1212.72 ccm (74.00 cubic inches) V2, four-stroke engine, delivering a commendable 55 horsepower at a respectable 7.0:1 compression ratio. This robust powertrain allows the bike to reach top speeds of 160 km/h (99.4 mph), providing exhilarating performance for long highway stretches or winding back roads. The air-cooled engine is paired with a 4-speed gearbox, offering smooth shifts and a satisfying riding experience. Riders will appreciate the harmonious balance between power and handling that the FLH Duo Glide provides, thanks to its tubular cradle frame and hydraulic telescopic front forks, which absorb bumps and ensure a comfortable ride over various terrains. The FLH Duo Glide is not just about performance; it boasts a host of features designed to enhance the riding experience. A spacious 14.19-litre fuel tank offers ample range for those long rides, while the adjustable dual coil-over-shocks in the rear suspension provide customizable comfort. The classic kick starter adds to the vintage charm, and the inclusion of a windscreen helps shield riders from the elements. Additionally, the FLH models feature higher compression than their FL counterparts, further enhancing their performance. Whether cruising down the highway or navigating city streets, the FLH Duo Glide exudes a sense of timeless elegance and unmatched character. **

Pros

  • Classic Styling: The quintessential Harley-Davidson aesthetic makes the FLH Duo Glide a head-turner on any road.
  • Comfortable Ride: With its adjustable rear suspension and ample seating, this motorcycle excels in long-distance touring.
  • Reliable Performance: The powerful V2 engine offers a strong output, ensuring smooth acceleration and highway cruising capabilities.

Cons

  • Weight: At 304 kg (670.2 pounds), the FLH Duo Glide can feel cumbersome for some riders, especially at low speeds or during parking maneuvers.
  • Kick Start Only: While nostalgic, the kick starter may not suit everyone’s preferences, particularly those accustomed to electric starters.
  • Limited Storage: The touring capabilities are somewhat compromised by minimal storage options compared to more modern touring bikes.
