Built around Kawasaki's sport touring motorcycle platform, the 2002 Kawasaki ZX-12R Ninja pairs a 1199 cc (73.2 cu in) liquid-cooled in-line four, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 178 HP (129.9 kW) at 10,500 rpm while maximum torque reaches 134 Nm (98.8 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 148.5 HP per liter and a 3,000 rpm working window between peak torque (7,500 rpm) and peak power (10,500 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
