Engineered by Triumph for the classic motorcycle segment, the 2025 Triumph Speed Twin 1200 relies on a 1200 cc (73.2 cu in) liquid-cooled twin, four-stroke powerplant. In factory specification, peak output is rated at 103.5 HP (75.5 kW) at 7,750 rpm while maximum torque reaches 83 Nm (61.2 lb-ft) at 4,250 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 86.3 HP per liter and a 3,500 rpm working window between peak torque (4,250 rpm) and peak power (7,750 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 1200 measures 215.9 kg (476 lbs) wet (curb), translating to a power-to-weight ratio of 0.48 HP/kg (2.09 kg per horsepower). Rider ergonomics and chassis geometry center around a 805 mm (31.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,413 mm (55.6 in) wheelbase engineered for quick, flickable steering geometry. The 14.5-liter (3.8 US gal) fuel tank paired with a rated consumption of 5.1 L/100 km provides an estimated theoretical range of roughly 284 km (176 miles) between fill-ups.
