The Harley-Davidson Fat Boy was a Softail cruiser motorcycle part of the Fat Boy series in H-D's range. The bike debuted in 1990 and was also known as the FLSTF from 1990 to 2017 and FLFB and FLFBS from 2018.
Over its production period, the Fat Boy underwent several design and technical modifications, including several displacement increases, starting in 1990 from 1,340cc until 2018, with the FLFB model at 1,746cc and FLFBS at 1,868cc.
In 2014, the American motorcycle manufacturer launched the Harley Davidson Fat Boy Special, a cruiser motorcycle with a more aggressive, edgier appearance than the standard Fat Boy.
The 2014 Special version was fitted with the same elements and technology as the original Fat Boy, including the frame, wheels, 1,690cc V-twin engine, and the six-speed Cruise Drive transmission, all in a more modern look.
In the appearance department, the 2013 Harley-Davidson Fat Boy Special packed black powder-coated elements instead of chrome and also featured a blacked-out appearance, with satin chromed head covers, cooling fins, mufflers, and rims.
In the performance department, the 2014 Harley-Davidson Fat Boy Special packed a 1,690cc four-stroke V-twin air-cooled engine with an electronic fuel injection system, offering smooth power and 132 Nm (97 lb-ft) torque at 3,250 rpm.
The bike rolled on black bullet-hole full disc aluminum wheels covered by valanced fenders and fitted with fat tires, 140 mm front, and 200 mm rear.
