Overview

Introducing the 1964 Harley-Davidson FLH Duo Glide, a classic touring motorcycle that embodies the spirit of freedom and adventure synonymous with the Harley-Davidson brand. As part of the legendary FL series, the Duo Glide represents a significant evolution in the touring category, offering both comfort and performance for those long journeys on the open road. With its iconic design and robust engineering, it quickly became a favorite among motorcycle enthusiasts who sought both style and substance in their rides. At the heart of the FLH Duo Glide lies a powerful 1212.72 ccm (74 cubic inches) V2 four-stroke engine, delivering a commendable 55 horsepower. This powerhouse is designed to cruise effortlessly at a top speed of 160 km/h (99.4 mph), making it an exhilarating ride for those who crave the thrill of speed. The engine’s 7.0:1 compression ratio complements its performance, allowing for smooth acceleration while maintaining reliability. Coupled with a 4-speed gearbox and a chain final drive, the FLH Duo Glide offers a satisfying riding experience characterized by both power and control, whether navigating city streets or winding country roads. The 1964 FLH Duo Glide is not just about performance; it is also laden with features that enhance its touring capabilities. The tubular cradle frame provides a robust foundation, while the hydraulic telescopic forks and swingarm rear suspension with dual coil-over-shocks—complete with 3-step adjustability—ensure a comfortable ride, absorbing the bumps along the way. Additionally, the expanding drum brakes at both the front and rear deliver dependable stopping power, instilling confidence in the rider. Notable styling elements, like the windscreens and a choice of vibrant colors including red, blue, and black, add to its allure, making the FLH Duo Glide a statement piece on any road. **

Pros

  • Impressive Power-to-Weight Ratio: With a power-to-weight ratio of 0.1809 HP/kg, the FLH Duo Glide offers a responsive riding experience.
  • Comfortable Touring Features: The adjustable rear suspension and ergonomic design make it ideal for long-distance rides.
  • Classic Aesthetic Appeal: Its iconic styling and color options ensure it stands out in any crowd, appealing to vintage motorcycle enthusiasts.

Cons
