Engineered by Kawasaki for the sport motorcycle segment, the 2021 Kawasaki Ninja ZX-10R KRT 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 200 HP (146 kW) at 13,000 rpm while maximum torque reaches 113.5 Nm (83.7 lb-ft) at 11,600 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 200.4 HP per liter and a 1,400 rpm working window between peak torque (11,600 rpm) and peak power (13,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Ninja ZX-10R KRT measures 207 kg (456 lbs) wet (curb), translating to a power-to-weight ratio of 0.97 HP/kg (1.04 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.
Within MotoLibrary's Kawasaki archive, this model family spans 3 indexed model years from 2021 to 2023, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
