Built around Harley-Davidson's touring motorcycle platform, the 2017 Harley-Davidson Road Glide Ultra pairs a 1753.5 cc (107 cu in) oil & air-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 91 HP (66.4 kW) at 5,450 rpm while maximum torque reaches 152 Nm (112.1 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 51.9 HP per liter and a 2,200 rpm working window between peak torque (3,250 rpm) and peak power (5,450 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Road Glide Ultra measures 425 kg (937 lbs) wet (curb), translating to a power-to-weight ratio of 0.21 HP/kg (4.67 kg per horsepower). Rider ergonomics and chassis geometry center around a 735 mm (28.9 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 18.9-liter (5 US gal) fuel tank paired with a rated consumption of 5.5 L/100 km provides an estimated theoretical range of roughly 344 km (214 miles) between fill-ups.
