HARLEY-DAVIDSON Firefighter Fat Boy (2009-2010) Specs, Performance & Photos

The Harley-Davidson Fat Boy was a cruiser motorcycle part of the Fat Boy series in H-D's range that debuted in 1990. The bike was also known as the FLSTF from 1990 to 2017, while from 2018, it was coded at FLFB and FLFBS.

The Fat Boy was well known for its powerful engine, classic style, and wide, muscular appearance. Some said the name came from the Fat Man and Little Boy atomic bombs dropped on Japan in WW2, but it proved to be just a descriptive name without any hints to their Japanese competitors.

In 2009, alongside the original model, the American maker launched the Harley-Davidson Firefighter Fat Boy, a special edition machine manufactured only for active or retired firefighter personnel. The bike featured a special livery, but other than that, it was identical to the original Fat Boy.

The 2009 Harley-Davidson Firefighter Fat Boy was delivered with a few new features, including a chromed horseshoe oil tank, a stainless steel, wide cruiser handlebar, a new 200 mm wide rear tire, and a chromed over/under shotgun exhaust system.

In the power department, the Firefighter Fat Boy used the same 1,584cc four-stroke air-cooled V-twin fuel-injected engine as the original Fat Boy, delivering smooth power and 127 Nm (94 lb-ft) torque with a peak force at 3,000 rpm.

The braking and suspension systems were carried from the original machine along with the V-twin engine and six-speed manual Cruise Drive transmission, delivering excellent performance.
