At the heart of the 2021 Kawasaki Ninja ZX-10RR sport motorcycle, Kawasaki relies on a 998 cc (60.9 cu in) liquid-cooled in-line four, four-stroke powerplant. In factory specification, peak output is rated at 204 HP (148.9 kW) at 14,000 rpm while maximum torque reaches 111.8 Nm (82.5 lb-ft) at 11,700 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 204.4 HP per liter and a 2,300 rpm working window between peak torque (11,700 rpm) and peak power (14,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Ninja ZX-10RR measures 207 kg (456 lbs) wet (curb), translating to a power-to-weight ratio of 0.99 HP/kg (1.01 kg per horsepower). Rider ergonomics and chassis geometry center around a 835 mm (32.9 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,450 mm (57.1 in) wheelbase engineered for balanced agility and highway composure. The 17-liter (4.5 US gal) fuel tank paired with a rated consumption of 5.9 L/100 km provides an estimated theoretical range of roughly 288 km (179 miles) between fill-ups.
