Overview

### Introducing the 1959 Harley-Davidson FL Duo Glide The 1959 Harley-Davidson FL Duo Glide is a quintessential example of mid-20th-century American touring motorcycles. Steeped in heritage and known for its iconic styling, the Duo Glide represents the pinnacle of comfort and performance during an era when long-distance riding was gaining popularity. With its robust build and classic aesthetics, this motorcycle appeals to both vintage enthusiasts and collectors, making it a standout piece in any garage. The Duo Glide seamlessly blends the rugged spirit of Harley-Davidson with the technological advancements of its time, creating a ride that embodies the freedom of the open road. ### Engine Performance and Riding Characteristics Underneath its timeless façade lies a potent V2, four-stroke engine with a displacement of 1212.72 ccm (74 cubic inches) that churns out a respectable 55 HP at 7200 RPM. With a compression ratio of 7.0:1, this powerhouse delivers a smooth, reliable performance that allows riders to conquer highways with confidence. The bike’s 4-speed gearbox and chain final drive offer a responsive ride, enabling effortless gear transitions whether you're cruising down the boulevard or tackling winding backroads. The air-cooled engine, combined with the hydraulic telescopic front forks and swingarm rear suspension with dual coil-over shocks, ensures that the ride remains both comfortable and controlled, making it perfect for those long-distance journeys. ### Key Features and Technology The Duo Glide stands out not only for its performance but also for its thoughtful engineering and features. With a tubular cradle frame, the bike boasts a sturdy foundation that enhances stability and handling. The expanding drum brakes at both the front and rear provide reliable stopping power, a crucial aspect for touring rides. Riders will appreciate the 14.19-litre fuel tank, which caters to those who desire to wander without frequent stops for refueling. Additionally, the option of a windscreen adds a layer of comfort, reducing wind resistance during long rides. Available in striking colors like black, red, blue, and turquoise, the 1959 FL Duo Glide is as much a statement of style as it is a testament to the innovation of its time. ###
