The Harley-Davidson Fat Boy was a cruiser motorcycle manufactured by H-D since 1990. The bike was known for its powerful engine, distinctive style, and wide, muscular appearance. From 1990 to 2017, the motorcycle was also known as the FLSTF, while from 2018, it was coded as FLFB and FLFBS.
A false etymology claimed that the bike's name was a symbolic insult to Japanese motorcycles from the Fat Man and Little Boy atomic bombs dropped on Japan in WW2. However, the H-D vice president Scott Miller said the name was simply descriptive and had nothing to do with their Japanese competitors.
The Harley-Davidson Fat Boy was represented by several key features, such as a teardrop-shaped fuel tank, a hardtail design, valanced fenders, and full disc aluminum wheels with a 200 mm wide rear tire.
In 2008, along with the original Fat Boy model, the American motorcycle manufacturer launched the Harley-Davidson Firefighter Fat Boy, a special edition model designed to pay tribute to the brave men and women who serve as firefighters.
The Firefighter model featured distinctive design elements that set it apart from the original model, including a custom paint scheme with firefighter-themed graphics, badges, and emblems.
Besides that, the bike was identical to the original model, packing the same 1,584cc air-cooled V-twin fuel-injected engine that delivered smooth power, fast acceleration, and 127 Nm (94 lb-ft) torque with a peak force at 3,000 rpm.
