Overview

Introducing the 2012 Harley-Davidson FLSTFB Softail Fat Boy Lo, a motorcycle that perfectly embodies the spirit of the open road with its custom-cruiser appeal and unmistakable presence. Positioned as a stylish and powerful option in Harley's lineup, the Fat Boy Lo combines classic design elements with modern engineering. With a starting price of $16,649 in the U.S. (subject to variation by country and options), this bike is not just a means of transportation; it's a statement of freedom and individuality that resonates with riders who appreciate the heritage of American motorcycling. At the heart of the Fat Boy Lo lies a robust 1,688 cc (103 cubic inches) V2, four-stroke engine, delivering an impressive torque of 133.84 Nm (98.7 ft-lbs) at a mere 3,000 RPM. This engine is coupled with a smooth 6-speed gearbox, ensuring that power is effortlessly transferred to the rear wheel via a durable belt final drive. Riders will appreciate the responsive acceleration and the satisfying rumble that only a Harley can provide. With air cooling and an advanced Electronic Sequential Port Fuel Injection (ESPFI) system, this motorcycle not only offers exhilarating performance but also maintains respectable fuel efficiency of approximately 5.60 litres per 100 km (42.00 mpg), allowing for longer journeys between fill-ups. The Fat Boy Lo is packed with features that enhance both comfort and style. Its mild steel tubular frame, complemented by a low seat height of just 24.3 inches, provides a commanding yet accessible riding position. The bike boasts a distinctive aesthetic, available in striking color options such as Vivid Black and Big Blue Pearl, while the hidden, horizontal-mounted rear suspension ensures a smooth ride without compromising the sleek profile. The front and rear brakes are equipped with single discs and optional ABS, providing riders with confidence and safety on the road. With a fuel capacity of nearly 19 litres, the Fat Boy Lo is built for those long rides where stopping for gas is the last thing on your mind. **

Pros

  • Stunning Design: The Fat Boy Lo's iconic silhouette and low profile make it a head-turner, appealing to custom-cruiser enthusiasts.
  • Impressive Torque: The 103 cubic-inch engine delivers strong low-end torque, ensuring spirited acceleration and an engaging riding experience.
  • Comfortable Ride: With its low seat height and effective suspension setup, the motorcycle offers a comfortable ride for both short trips and long hauls.

Cons

  • Weight: At 700 pounds (317.5 kg), the Fat Boy Lo can feel cumbersome in tight maneuvers or at low speeds for less experienced riders.
  • Limited Ground Clearance: The ground clearance of 4.8 inches may limit aggressive cornering for those who prefer sporty riding dynamics.
  • Price Point: While it offers exceptional quality and performance, the starting price may be a barrier for some potential buyers in the cruiser market.
