Overview

Introducing the 1964 Harley-Davidson FL Duo Glide: A Classic Touring Icon The 1964 Harley-Davidson FL Duo Glide stands as a quintessential representation of American motorcycle culture, seamlessly blending classic styling with robust performance. As part of the renowned FL series, this model was tailor-made for long-distance touring enthusiasts looking to conquer the open road. With its distinctive lines, chrome accents, and the iconic Harley-Davidson badge, the Duo Glide not only captures the essence of freedom but also promises a ride that remains etched in memory long after the engine has cooled. In an era when touring motorcycles were gaining traction, the Duo Glide carved out a niche, appealing to riders who craved comfort and stability on their long journeys. At the heart of the FL Duo Glide lies a powerful 1212.72 ccm (74.00 cubic inches) V2 four-stroke engine, which delivers a spirited 55 horsepower at 7200 RPM. This potent engine, coupled with a 4-speed gearbox and chain final drive, empowers the Duo Glide to achieve a top speed of 160 km/h (99.4 mph). Its smooth performance is bolstered by a compression ratio of 7.0:1, a classic characteristic of Harley's engineering prowess. Riders will appreciate the responsive throttle and the unmistakable growl of the engine as it propels them forward, providing an exhilarating experience whether cruising down the highway or navigating through city streets. The air-cooled design ensures that the engine remains reliable, and the generous 14.19-liter fuel capacity allows for extended journeys without frequent stops. The FL Duo Glide is equipped with features that enhance both comfort and capability, making it a true touring motorcycle. Its tubular cradle frame offers stability, while the hydraulic telescopic forks and dual coil-over shocks provide a plush ride over uneven terrains. Safety is addressed with expanding drum brakes on both the front and rear, ensuring dependable stopping power. Additionally, the inclusion of a windscreen not only deflects wind but also adds to rider comfort during long rides. The classic kick starter maintains the traditional feel of riding, allowing enthusiasts to connect with the bike's old-school roots while enjoying modern reliability. **

    • Solid Performance: The 74 cubic inch engine delivers a balance of power and efficiency, making it suitable for both highway cruising and city commuting.
