Positioned in Kawasaki's sport motorcycle lineup, the 2021 Kawasaki Ninja H2R utilizes a 998 cc (60.9 cu in) liquid-cooled in-line four, four-stroke layout. In factory specification, peak output is rated at 228 HP (166.4 kW) at 11,500 rpm while maximum torque reaches 141.7 Nm (104.5 lb-ft) at 11,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 228.5 HP per liter and a 500 rpm working window between peak torque (11,000 rpm) and peak power (11,500 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Ninja H2R measures 215.9 kg (476 lbs) wet (curb), translating to a power-to-weight ratio of 1.06 HP/kg (0.95 kg per horsepower). Rider ergonomics and chassis geometry center around a 831 mm (32.7 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 supports practical everyday commuting and weekend road stints.
