At the heart of the 2019 Norton Superlight classic motorcycle, Norton relies on a 650 cc (39.7 cu in) liquid-cooled twin, four-stroke powerplant. In factory specification, maximum torque reaches 75 Nm (55.3 lb-ft), transferring power to the rear wheel through a 4-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 82.0 x 61.0 mm (3.2 x 2.4 inches) with a 13.4:1 compression ratio.
On the scales, the Superlight measures 158 kg (348 lbs) dry. Rider ergonomics and chassis geometry center around a 924 mm (36.4 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,399 mm (55.1 in) wheelbase engineered for quick, flickable steering geometry.
