2015 Harley-Davidson Tri Glide Ultra Technical Analysis & Specification Breakdown
At the heart of the 2015 Harley-Davidson Tri Glide Ultra touring motorcycle, Harley-Davidson relies on a 1688 cc (103 cu in) air-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 85.8 HP (62.6 kW) at 5,100 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 1,850 rpm working window between peak torque (3,250 rpm) and peak power (5,100 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Tri Glide Ultra measures 567 kg (1250 lbs) wet (curb), translating to a power-to-weight ratio of 0.15 HP/kg (6.61 kg per horsepower). Rider ergonomics and chassis geometry center around a 688 mm (27.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,692 mm (66.6 in) wheelbase engineered for planted straight-line stability. The 22.71-liter (6 US gal) fuel tank paired with a rated consumption of 6.19 L/100 km provides an estimated theoretical range of roughly 367 km (228 miles) between fill-ups.
