At the heart of the 2023 Norton V4CR prototype - concept model motorcycle, Norton pairs a 1200 cc (73.2 cu in) liquid-cooled v4, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 185 HP (135 kW) at 12,500 rpm while maximum torque reaches 130 Nm (95.9 lb-ft) at 10,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 154.2 HP per liter and a 2,500 rpm working window between peak torque (10,000 rpm) and peak power (12,500 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the V4CR measures 180 kg (397 lbs) dry, translating to a power-to-weight ratio of 1.03 HP/kg (0.97 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,430 mm (56.3 in) wheelbase engineered for balanced agility and highway composure. The 18-liter (4.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
