2025 Harley-Davidson Tri Glide Ultra Technical Analysis & Specification Breakdown
At the heart of the 2025 Harley-Davidson Tri Glide Ultra touring motorcycle, Harley-Davidson pairs a 1868 cc (114 cu in) air-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 93 HP (67.9 kW) at 5,020 rpm while maximum torque reaches 162.7 Nm (120 lb-ft) at 2,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and belt final drive. With a specific output of 49.8 HP per liter and a 2,520 rpm working window between peak torque (2,500 rpm) and peak power (5,020 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 561.1 kg (1237 lbs) wet (curb), translating to a power-to-weight ratio of 0.17 HP/kg (6.03 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 1,670 mm (65.7 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.
