2015 Harley-Davidson Street Glide Technical Analysis & Specification Breakdown
Positioned in Harley-Davidson's touring motorcycle lineup, the 2015 Harley-Davidson Street Glide relies on a 1688 cc (103 cu in) oil & air-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 85.8 HP (62.6 kW) at 5,000 rpm while maximum torque reaches 138 Nm (101.8 lb-ft) at 3,250 rpm, transferring power to the rear wheel through a 6-speed gearbox and belt final drive. With a specific output of 50.8 HP per liter and a 1,750 rpm working window between peak torque (3,250 rpm) and peak power (5,000 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Street Glide measures 367.9 kg (811 lbs) wet (curb), translating to a power-to-weight ratio of 0.23 HP/kg (4.29 kg per horsepower). Rider ergonomics and chassis geometry center around a 663 mm (26.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,613 mm (63.5 in) wheelbase engineered for planted straight-line stability. The 22.71-liter (6 US gal) fuel tank paired with a rated consumption of 5.6 L/100 km provides an estimated theoretical range of roughly 406 km (252 miles) between fill-ups.
