The Harley-Davidson Fat Boy was a motorcycle manufactured by H-D from 1990, known for its distinctive style, muscular appearance, and powerful engine. The bike was also known as the FLSTF from 1990 to 2017, while from 2018, the bike was coded as FLFB and FLFBS.
Over its production period, the bike underwent various design and technical changes, including a displacement increase for the 2000 model year from 1,330cc to 1,450cc and another one in 2007 from 1,450cc to 1,584cc.
Besides the 2007 engine upgrade, the bike also received some new enhancements, including a 200 mm wide rear wheel, a chopper-style rear fender, a custom front fender, an internally wired handlebar, and a Fat Bob fuel tank.
Further upgrades included a horseshoe oil tank, floorboards with a heel-toe shifter, a chrome front fork nacelle, custom graphics on the front fender, fuel tank, and rear fender, and full disc wheels with a bullet-style design.
In 2008, the American motorcycle maker launched the Harley-Davidson Fat Boy, a cruiser motorcycle powered by a new 1,584cc air-cooled V-twin engine with a fuel injection system that delivered smoother power and 127 Nm (94 lb-ft) torque at 3,000 rpm.
The braking system was retained from previous models, still packing a four-piston caliper with a 292 mm disc on the front wheel and a 292 mm disc with a four-piston caliper on the rear wheel.
