HARLEY-DAVIDSON Fat Boy (2003-2004) Specs, Performance & Photos

The Harley-Davidson FLSTF was a cruiser motorcycle, also known as the Fat Boy, first released in 1990 and part of the Fat Boy line in H-D's range. The bike was known for its muscular appearance, distinctive styling, and powerful engine.

In 2003, the American manufacturer launched the Harley-Davidson Fat Boy, a motorcycle that featured several modifications over its production time, including the engine displacement increase in 2000 from 1,337cc to 1,450cc.

For appearance, the bike featured several classic elements, such as a large round headlight in a chromed housing, a teardrop-shaped fuel tank, a single-piece dual seat, a dual chromed exhaust system, and valanced fenders covering a pair of solid disc aluminum wheels.

In the performance department, the 2003 Harley-Davidson Fat Boy was powered by a 1,450cc air-cooled V-twin engine with an Electronic Sequential Port Fuel Injection (ESPFI) system, boasting 67 hp with a peak at 5,200 rpm and 117 Nm (86 lb-ft) torque at 3,500 rpm.

The engine power was sent to a five-speed manual transmission with a nine-plate wet clutch and delivered to the rear wheel through a final belt drive.

The braking system remained unchanged, handled by a 292 mm with a four-piston front and rear caliper, delivering excellent stopping power.

For suspension, the bike packed a 41 mm telescopic fork with 130 mm wheel travel and beer can covers on the front. In contrast, the rear end was operated by a horizontal-mounted single shock absorber with 109 mm wheel travel.
