Overview

### 2009 Harley-Davidson FLSTF Fat Boy: A Custom-Cruiser Icon The 2009 Harley-Davidson FLSTF Fat Boy stands as a testament to the brand's storied legacy in the custom-cruiser segment. With its massive presence and unmistakable silhouette, the Fat Boy has become an icon for riders who crave both style and substance. Known for its beefy design and robust performance, this motorcycle appeals to those who appreciate the art of cruising while demanding the power and comfort necessary for longer journeys. Whether you're navigating through city streets or cruising along open highways, the Fat Boy delivers a distinctive Harley experience that is both timeless and exhilarating. At the heart of the Fat Boy is a formidable 1584cc V2, four-stroke engine that roars with authority. Producing 120 Nm (88.5 ft-lbs) of torque at a low 3300 RPM, this powerplant ensures that riders can accelerate effortlessly, making it ideal for both spirited rides and relaxed cruising. The air-cooled engine is paired with an efficient 6-speed gearbox, allowing for smooth transitions through gears while maintaining a solid connection to the road. With a compression ratio of 9.2:1 and Electronic Sequential Port Fuel Injection (ESPFI), this motorcycle achieves not only robust power delivery but also improved throttle response, ensuring that every twist of the wrist is met with exhilarating performance. Beyond its powerful engine, the 2009 Fat Boy is packed with features designed for comfort and style. The iconic design is complemented by a black powder-coated engine adorned with chrome treatment covers, giving it a striking visual appeal. Riders will appreciate the full-length rider footboards and the two-piece Softail® classic seat, which ensures that long hours in the saddle are met with comfort. The presence of forward-mounted footpegs and a nostalgic fuel tank console adds to the bike's classic aesthetic while enhancing its rider-friendly ergonomics. The motorcycle is available in several eye-catching colors, including Vivid Black and Flame Blue Pearl, ensuring that it stands out wherever it goes. ####

    • Iconic Style: With its classic design elements and chrome accents, the Fat Boy is not just a motorcycle; it’s a statement of style on two wheels.
    • Comfortable Ride: The well-designed seat and riding position promote comfort for both the rider and passenger, making long rides enjoyable.
    • Weight: At 313 kg (690 lbs), the Fat Boy can feel heavy at low speeds, which may deter novice riders or those looking for a more nimble bike.
    • Fuel Capacity: While 18.9 liters (4.99 gallons) is decent, some riders may find the fuel range limiting on longer journeys without frequent stops.
