Built around Triumph's allround motorcycle platform, the 2021 Triumph Speed Twin relies on a 1200 cc (73.2 cu in) liquid-cooled twin, four-stroke powerplant. In factory specification, peak output is rated at 96 HP (70.1 kW) at 6,750 rpm while maximum torque reaches 112 Nm (82.6 lb-ft) at 4,950 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 80 HP per liter and a 1,800 rpm working window between peak torque (4,950 rpm) and peak power (6,750 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 Speed Twin measures 196 kg (432 lbs) dry, translating to a power-to-weight ratio of 0.49 HP/kg (2.04 kg per horsepower). Rider ergonomics and chassis geometry center around a 807 mm (31.8 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,430 mm (56.3 in) wheelbase engineered for balanced agility and highway composure. The 14.5-liter (3.8 US gal) fuel tank paired with a rated consumption of 4.8 L/100 km provides an estimated theoretical range of roughly 302 km (188 miles) between fill-ups.
Within MotoLibrary's Triumph archive, this model family spans 28 indexed model years from 1937 to 2022, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
