2017 Norton Commando 961 SF Mk II Technical Analysis & Specification Breakdown

Positioned in Norton's classic motorcycle lineup, the 2017 Norton Commando 961 SF Mk II relies on a 961 cc (58.6 cu in) air-cooled twin, four-stroke powerplant. In factory specification, peak output is rated at 80 HP (58.4 kW) at 7,700 rpm while maximum torque reaches 90 Nm (66.4 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 83.2 HP per liter and a 1,700 rpm working window between peak torque (6,000 rpm) and peak power (7,700 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 Commando 961 SF Mk II measures 203 kg (448 lbs) wet (curb), translating to a power-to-weight ratio of 0.39 HP/kg (2.54 kg per horsepower). Rider ergonomics and chassis geometry center around a 813 mm (32 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,420 mm (55.9 in) wheelbase engineered for balanced agility and highway composure. The 17-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
