Built around Triumph's custom - cruiser motorcycle platform, the 2010 Triumph Speedmaster relies on a 865 cc (52.8 cu in) air-cooled twin, four-stroke powerplant. In factory specification, peak output is rated at 61.7 HP (45 kW) at 6,800 rpm while maximum torque reaches 74 Nm (54.6 lb-ft) at 3,300 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 71.3 HP per liter and a 3,500 rpm working window between peak torque (3,300 rpm) and peak power (6,800 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 Speedmaster measures 250 kg (551 lbs) wet (curb), translating to a power-to-weight ratio of 0.25 HP/kg (4.05 kg per horsepower). Rider ergonomics and chassis geometry center around a 720 mm (28.3 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,655 mm (65.2 in) wheelbase engineered for planted straight-line stability. The 19.3-liter (5.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
