1962 Norton Jubilee Technical Analysis & Specification Breakdown

At the heart of the 1962 Norton Jubilee allround motorcycle, Norton features a 249 cc (15.2 cu in) air-cooled twin, four-stroke configuration. In factory specification, peak output is rated at 11.7 HP (8.5 kW) at 7,750 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 47 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.

On the scales, the Jubilee measures 150 kg (331 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (12.82 kg per horsepower). Rider ergonomics and chassis geometry center around a 762 mm (30 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,359 mm (53.5 in) wheelbase engineered for quick, flickable steering geometry. The 13.6-liter (3.6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 121 km/h (75 mph).
