Positioned in Triumph's classic motorcycle lineup, the 2025 Triumph Speed Twin 900 relies on a 900 cc (54.9 cu in) liquid-cooled twin, four-stroke powerplant. In factory specification, peak output is rated at 65 HP (47.4 kW) at 7,500 rpm while maximum torque reaches 80 Nm (59 lb-ft) at 3,800 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 72.2 HP per liter and a 3,700 rpm working window between peak torque (3,800 rpm) and peak power (7,500 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 900 measures 216 kg (476 lbs) wet (curb), translating to a power-to-weight ratio of 0.3 HP/kg (3.32 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,435 mm (56.5 in) wheelbase engineered for balanced agility and highway composure. The 12-liter (3.2 US gal) fuel tank paired with a rated consumption of 4.1 L/100 km provides an estimated theoretical range of roughly 293 km (182 miles) between fill-ups.
