Positioned in Triumph's classic motorcycle lineup, the 2010 Triumph Bonneville utilizes a 865 cc (52.8 cu in) air-cooled twin, four-stroke layout. In factory specification, peak output is rated at 67.1 HP (48.9 kW) at 7,500 rpm while maximum torque reaches 69 Nm (50.9 lb-ft) at 5,800 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 77.6 HP per liter and a 1,700 rpm working window between peak torque (5,800 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 Bonneville measures 225 kg (496 lbs) wet (curb), translating to a power-to-weight ratio of 0.3 HP/kg (3.35 kg per horsepower). Rider ergonomics and chassis geometry center around a 740 mm (29.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,490 mm (58.7 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.
