At the heart of the 2017 Triumph Thunderbird LT touring motorcycle, Triumph utilizes a 1699 cc (103.7 cu in) liquid-cooled twin, four-stroke layout. In factory specification, peak output is rated at 94 HP (68.6 kW) at 5,400 rpm while maximum torque reaches 146 Nm (107.7 lb-ft) at 2,750 rpm, transferring power to the rear wheel through a 6-speed gearbox and belt final drive. With a specific output of 55.3 HP per liter and a 2,650 rpm working window between peak torque (2,750 rpm) and peak power (5,400 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Thunderbird LT measures 380 kg (838 lbs) wet (curb), translating to a power-to-weight ratio of 0.25 HP/kg (4.04 kg per horsepower). Rider ergonomics and chassis geometry center around a 700 mm (27.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,665 mm (65.6 in) wheelbase engineered for planted straight-line stability. The 26-liter (6.9 US gal) fuel tank paired with a rated consumption of 6.19 L/100 km provides an estimated theoretical range of roughly 420 km (261 miles) between fill-ups.
