Overview

The 2009 Harley-Davidson FXDF Dyna Fat Bob stands out in the custom-cruiser category, embodying the spirit of freedom and the open road that Harley-Davidson is renowned for. With its aggressive styling and powerful performance, the Fat Bob appeals to riders who appreciate both aesthetics and the thrill of the ride. Its low-slung profile, robust presence, and iconic Harley-Davidson heritage make it a formidable choice for those seeking a bike that balances comfort with a commanding road presence. At the heart of the Fat Bob is a robust 1584cc V2, four-stroke engine that delivers an impressive torque of 127 Nm at 3500 RPM. This engine not only churns out power but does so with an exhilarating roar that will make any rider's heart race. The air-cooled system, combined with a 6-speed gearbox and a belt final drive, ensures smooth acceleration and effortless cruising on long stretches of highway. With a compression ratio of 9.2:1 and a bore/stroke of 95.3 x 111.1 mm, the Fat Bob offers a responsive throttle that enhances its performance in both urban and open road settings. The 2009 FXDF Dyna Fat Bob is not just about raw power; it comes packed with features that elevate the riding experience. The motorcycle boasts a sturdy mild steel tubular frame that supports a polished aluminum fork triple clamp for the front suspension, providing a smooth ride over varying terrain. The dual disc brakes in the front and a single disc in the rear offer reliable stopping power, while the low-profile fenders and chrome accents lend a touch of classic flair. Riders will appreciate the forward-mounted footpegs and the comfortable one-piece, two-up Dyna classic seat, which makes long rides enjoyable for both the rider and passenger. **

Pros

  • Powerful Performance: The 1584cc V2 engine delivers excellent torque for an exhilarating ride.
  • Stylish Design: The aggressive aesthetics combined with chrome accents create a visually stunning motorcycle.
  • Comfortable Ride: With a low seat height and well-designed ergonomics, it offers comfort for both short and long rides.

Cons

  • Weight: At 305 kg (672 pounds), the Fat Bob's heft may challenge new or less experienced riders.
  • Limited Passenger Comfort: While the seat is designed for two, the passenger space may feel cramped on longer journeys.
  • Fuel Capacity: With a fuel tank of 19.3 liters (5.1 gallons), the range may not satisfy those who plan extensive long-distance rides without frequent stops.
