Technical Overview
2025 Harley-Davidson Street Glide Ultra Technical Analysis & Specification Breakdown
At the heart of the 2025 Harley-Davidson Street Glide Ultra touring motorcycle, Harley-Davidson utilizes a 1917.4 cc (117 cu in) air-cooled v2, four-stroke layout. In factory specification, peak output is rated at 105 HP (76.6 kW) at 4,600 rpm while maximum torque reaches 176.3 Nm (130 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 54.8 HP per liter and a 1,350 rpm working window between peak torque (3,250 rpm) and peak power (4,600 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 Ultra measures 392.8 kg (866 lbs) wet (curb), translating to a power-to-weight ratio of 0.27 HP/kg (3.74 kg per horsepower). Rider ergonomics and chassis geometry center around a 683 mm (26.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,625 mm (64 in) wheelbase engineered for planted straight-line stability. The 22.71-liter (6 US gal) fuel tank paired with a rated consumption of 5.35 L/100 km provides an estimated theoretical range of roughly 424 km (263 miles) between fill-ups.
