1990: The Fat Boy model debuts in one color, Fine Silver Metallic, powered by a rigid-mounted Evolution V-Twin engine.

The Fat Boy model was inspired by a custom Harley motorcycle based on the Softail platform created in 1987 at Harley-Davidson Montréal by the dealership general manager Duc Dufour and technician Denis Lavoie, which they called a Lowboy. That bike featured slammed rear suspension, an aluminum disc wheel and fiberglass fender on the front and a wide handlebar. Spotted by Harley-Davidson Executive Jerry Wilke, an example was shipped to Milwaukee. While the Lowboy custom offered some inspiration, the motorcycle that would become the Fat Boy model was created by the H-D styling team led by Willie G. Davidson and Louie Netz.
