HARLEY-DAVIDSONFat Boy 1990 - 1991

　　The Harley-Davidson Fat Boy was a motorcycle manufactured since 1990 and designed by the H-D's styling director, Willie G. Davidson, and Louie Netz. The bikes produced from 1990 to 2017 had the FLSTF code name, while those manufactured from 2018 were coded as FLFBS and FLFB.

　　Also, the American manufacturer Harley-Davidson built a Fat Boy prototype in Milwaukee for the Daytona Bike Week rally at Daytona Beach in 1988 and 1989.

　　The Fat Boy had a classic cruiser design offering a muscular appearance and an aggressive look. Also, the bike quickly gained popularity and became an iconic part of Harley-Davidson's range.

　　Some said that the Fat Boy designation was a symbolic insult to the Japanese motorcycles, named after the Fat Man and Little Boy, which were the atomic bombs dropped on Japan in World War Two. The Fat Boy designation was given due to its wide design and was simply a descriptive name.

　　For appearance, the bike featured a wide handlebar, a round headlight with a chromed housing, valanced front, and rear fenders, a teardrop-shaped fuel tank, a one-piece dual seat with a low riding position, and solid cast disc wheels.

　　The 1990 Harley-Davidson Fat Boy's power came from a 1,337cc four-stroke V-twin air-cooled engine, fed by a Keihin carburetor, boasting 67 hp with a peak force at 6,000 rpm and 97 Nm (72 lb-ft) torque at 2,350 rpm.
