Positioned in Triumph's classic motorcycle lineup, the 2002 Triumph Bonneville features a 790 cc (48.2 cu in) air-cooled twin, four-stroke configuration. In factory specification, peak output is rated at 61 HP (44.5 kW) at 7,400 rpm while maximum torque reaches 60 Nm (44.3 lb-ft) at 3,500 rpm, transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 77.2 HP per liter and a 3,900 rpm working window between peak torque (3,500 rpm) and peak power (7,400 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 measures 205 kg (452 lbs) dry, translating to a power-to-weight ratio of 0.3 HP/kg (3.36 kg per horsepower). Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,493 mm (58.8 in) wheelbase engineered for balanced agility and highway composure. The 16-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
