Built around Harley-Davidson's custom - cruiser motorcycle platform, the 2020 Harley-Davidson Softail Low Rider S utilizes a 1868.2 cc (114 cu in) air-cooled v2, four-stroke layout. In factory specification, peak output is rated at 86 HP (62.8 kW) at 5,020 rpm while maximum torque reaches 161.4 Nm (119 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 46 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 Low Rider S measures 308 kg (679 lbs) wet (curb), translating to a power-to-weight ratio of 0.28 HP/kg (3.58 kg per horsepower). Rider ergonomics and chassis geometry center around a 673 mm (26.5 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 18.9-liter (5 US gal) fuel tank paired with a rated consumption of 5 L/100 km provides an estimated theoretical range of roughly 378 km (235 miles) between fill-ups.
