Engineered by Triumph for the classic motorcycle segment, the 2018 Triumph Bonneville T100 features a 900 cc (54.9 cu in) air-cooled twin, four-stroke configuration. In factory specification, peak output is rated at 55 HP (40.1 kW) at 5,900 rpm while maximum torque reaches 80 Nm (59 lb-ft) at 3,230 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 61.1 HP per liter and a 2,670 rpm working window between peak torque (3,230 rpm) and peak power (5,900 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 T100 measures 233 kg (514 lbs) wet (curb), translating to a power-to-weight ratio of 0.24 HP/kg (4.24 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 14.38-liter (3.8 US gal) fuel tank paired with a rated consumption of 3.83 L/100 km provides an estimated theoretical range of roughly 375 km (233 miles) between fill-ups.
