HARLEY-DAVIDSON Fat Boy (1992-1993) Specs, Performance & Photos

In 1992, the American bike maker launched the Harley-Davidson Fat Boy, a V-twin soft-tail cruiser machine that debuted in 1990. The bike was designed by Willie G. Davidson, the styling director of H-D, and Louie Netz.

Also, in 1988 and 1989, Harley-Davidson manufactured a Fat Boy prototype for the Daytona Bike Week rally at Daytona Beach in Milwaukee. The Fat Boy models manufactured from 1990 to 2017 were designated as FLSTF, while the ones produced from 2018 were coded as FLFB and FLFBS.

The 1992 Fat Boy was part of the iconic Fat Boy line-up in Harley-Davidson's range and was known for its muscular appearance, distinctive styling, and massive performance. The 1992 machine retained the characteristics of previous models without any design and performance modifications.

The 1992 Harley-Davidson Fat Boy came equipped with a wide handlebar, a round headlight with a chromed housing, a one-piece dual seat, a passenger backrest, disc wheels, valanced fenders, a dual exhaust system, and optional leather saddlebags.

In the power department, the bike had a 1,337cc four-stroke V-twin air-cooled engine fed by a 38 mm Keihin carburetor, delivering an output power of 67 hp with maximum strength at 6,000 rpm and 97 Nm (72 lb-ft) torque at 2,350 rpm.

Some said the bike was named after the Fat Man and Little Boy atomic bombs dropped on Japan in World War Two, but the name was simply descriptive. The Fat Boy was somewhat wider than other machines when viewed head-on.
