Engineered by Harley-Davidson for the custom - cruiser motorcycle segment, the 2019 Harley-Davidson Softail Fat Boy 114 features a 1868 cc (114 cu in) air-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 94 HP (68.6 kW) at 5,020 rpm while maximum torque reaches 155 Nm (114.3 lb-ft) at 3,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and belt final drive. With a specific output of 50.3 HP per liter and a 2,020 rpm working window between peak torque (3,000 rpm) and peak power (5,020 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Softail Fat Boy 114 measures 317 kg (699 lbs) wet (curb), translating to a power-to-weight ratio of 0.3 HP/kg (3.37 kg per horsepower). Rider ergonomics and chassis geometry center around a 675 mm (26.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,665 mm (65.6 in) wheelbase engineered for planted straight-line stability. The 18.93-liter (5 US gal) fuel tank paired with a rated consumption of 5.6 L/100 km provides an estimated theoretical range of roughly 338 km (210 miles) between fill-ups.
