Fat Boy

1996 Harley-Davidson Fat Boy Technical Analysis & Specification Breakdown

Positioned in Harley-Davidson's custom - cruiser motorcycle lineup, the 1996 Harley-Davidson Fat Boy utilizes a 1338 cc (81.6 cu in) air-cooled v2, four-stroke layout. In factory specification, peak output is rated at 57 HP (41.6 kW) at 5,000 rpm while maximum torque reaches 97 Nm (71.5 lb-ft) at 2,350 rpm, transferring power to the rear wheel through a 5-speed gearbox and belt final drive. With a specific output of 42.6 HP per liter and a 2,650 rpm working window between peak torque (2,350 rpm) and peak power (5,000 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.

On the scales, the Fat Boy measures 284 kg (626 lbs) dry, translating to a power-to-weight ratio of 0.2 HP/kg (4.98 kg per horsepower). Rider ergonomics and chassis geometry center around a 692 mm (27.2 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops.
