Softail Slim S

2017 Harley-Davidson Softail Slim S Technical Analysis & Specification Breakdown

Positioned in Harley-Davidson's custom - cruiser motorcycle lineup, the 2017 Harley-Davidson Softail Slim S pairs a 1801 cc (109.9 cu in) air-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 92 HP (67.2 kW) at 5,010 rpm while maximum torque reaches 145 Nm (107 lb-ft) at 4,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and belt final drive. With a specific output of 51.1 HP per liter and a 1,010 rpm working window between peak torque (4,000 rpm) and peak power (5,010 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.

On the scales, the Softail Slim S measures 321 kg (708 lbs) wet (curb), translating to a power-to-weight ratio of 0.29 HP/kg (3.49 kg per horsepower). Rider ergonomics and chassis geometry center around a 650 mm (25.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,636 mm (64.4 in) wheelbase engineered for planted straight-line stability. The 18.9-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.
