2021 Harley-Davidson Fat Bob 114 Technical Analysis & Specification Breakdown

At the heart of the 2021 Harley-Davidson Fat Bob 114 custom - cruiser motorcycle, Harley-Davidson pairs a 1868 cc (114 cu in) air-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 94 HP (68.6 kW) at 5,020 rpm while maximum torque reaches 160 Nm (118 lb-ft) at 3,500 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 1,520 rpm working window between peak torque (3,500 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 Fat Bob 114 measures 306.6 kg (676 lbs) wet (curb), translating to a power-to-weight ratio of 0.31 HP/kg (3.26 kg per horsepower). Rider ergonomics and chassis geometry center around a 704 mm (27.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,615 mm (63.6 in) wheelbase engineered for planted straight-line stability. The 13.6-liter (3.6 US gal) fuel tank paired with a rated consumption of 5 L/100 km provides an estimated theoretical range of roughly 272 km (169 miles) between fill-ups.
