Positioned in Triumph's classic motorcycle lineup, the 2015 Triumph Thruxton Ace utilizes a 865 cc (52.8 cu in) air-cooled twin, four-stroke layout. In factory specification, peak output is rated at 69 HP (50.4 kW) at 7,400 rpm while maximum torque reaches 69 Nm (50.9 lb-ft) at 5,800 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 79.8 HP per liter and a 1,600 rpm working window between peak torque (5,800 rpm) and peak power (7,400 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Thruxton Ace measures 230 kg (507 lbs) wet (curb), translating to a power-to-weight ratio of 0.3 HP/kg (3.33 kg per horsepower). Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,490 mm (58.7 in) wheelbase engineered for balanced agility and highway composure. The 16-liter (4.2 US gal) fuel tank paired with a rated consumption of 5.47 L/100 km provides an estimated theoretical range of roughly 293 km (182 miles) between fill-ups.
