2023 Harley-Davidson Low Rider ST Technical Analysis & Specification Breakdown
At the heart of the 2023 Harley-Davidson Low Rider ST custom - cruiser motorcycle, Harley-Davidson features a 1923 cc (117.3 cu in) air-cooled v2, four-stroke configuration. In factory specification, 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. Internal engine geometry specifies a bore and stroke of 103.5 x 114.3 mm (4.1 x 4.5 inches) with a 10.2:1 compression ratio.
On the scales, the Low Rider ST measures 308 kg (679 lbs) wet (curb). 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.
