2024 Harley-Davidson Low Rider ST Technical Analysis & Specification Breakdown
Engineered by Harley-Davidson for the custom - cruiser motorcycle segment, the 2024 Harley-Davidson Low Rider ST relies on a 1923 cc (117.3 cu in) air-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 103 HP (75.2 kW) at 4,750 rpm while maximum torque reaches 169.5 Nm (125 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 53.6 HP per liter and a 1,250 rpm working window between peak torque (3,500 rpm) and peak power (4,750 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Low Rider ST measures 327 kg (721 lbs) wet (curb), translating to a power-to-weight ratio of 0.31 HP/kg (3.17 kg per horsepower). Rider ergonomics and chassis geometry center around a 686 mm (27 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.
