Positioned in Triumph's classic motorcycle lineup, the 2011 Triumph Bonneville Sixty relies on a 865 cc (52.8 cu in) air-cooled twin, four-stroke powerplant. In factory specification, peak output is rated at 66 HP (48.2 kW) at 7,500 rpm while maximum torque reaches 67.8 Nm (50 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 76.3 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 Sixty measures 224.5 kg (495 lbs) wet (curb), translating to a power-to-weight ratio of 0.29 HP/kg (3.4 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 1,499 mm (59 in) wheelbase engineered for balanced agility and highway composure. The 15.9-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
