Overview

Introducing the 2012 Harley-Davidson FLSTFB Fat Boy Special, a striking embodiment of the custom-cruiser segment that perfectly balances raw power and timeless style. This motorcycle stands as a testament to Harley's commitment to craftsmanship and innovation, appealing to both seasoned riders and those drawn to the allure of classic American motorcycles. With its muscular stance and iconic silhouette, the Fat Boy Special is more than just a bike; it's a statement of individuality and freedom on two wheels. At the heart of the Fat Boy Special lies a robust 1690cc V2, four-stroke engine that delivers a thrilling performance. With a compression ratio of 9.6:1 and a bore and stroke of 98.4 x 111.1 mm, this powerplant churns out ample torque, allowing riders to feel the exhilarating rush of acceleration right from the start. The electronic sequential port fuel injection (ESPFI) ensures smooth throttle response, while the 6-speed gearbox provides seamless shifting, making highway cruising a breeze. Coupled with an air cooling system, the engine maintains optimal temperatures, ensuring reliability during long rides. The bike’s substantial weight of 313 kg (690 lbs) gives it a planted feel, instilling confidence as it glides through corners and highways alike. Beyond its powerful engine, the 2012 Fat Boy Special is outfitted with features that enhance both comfort and control. The double disc brakes at the front and a single disc at the rear provide confident stopping power, ensuring safety is never compromised. The motorcycle’s rake of 31.6° and a trail of 147 mm contribute to its stable handling characteristics, making it easy to maneuver through tight spaces. With an accommodating fuel capacity of 18.9 liters (4.99 gallons), riders can embark on longer journeys without the constant worry of refueling. The electric starter adds a modern touch to this classic machine, blending convenience with heritage. **
