Engineered by Triumph for the classic motorcycle segment, the 2022 Triumph Bonneville T120 pairs a 1200 cc (73.2 cu in) liquid-cooled twin, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 79.1 HP (57.8 kW) at 6,550 rpm while maximum torque reaches 105 Nm (77.4 lb-ft) at 3,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 65.9 HP per liter and a 3,050 rpm working window between peak torque (3,500 rpm) and peak power (6,550 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 Bonneville T120 measures 235.9 kg (520 lbs) wet (curb), translating to a power-to-weight ratio of 0.34 HP/kg (2.98 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,450 mm (57.1 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 4.5 L/100 km provides an estimated theoretical range of roughly 322 km (200 miles) between fill-ups.
