Engineered by Kawasaki for the sport motorcycle segment, the 2021 Kawasaki Ninja H2 SX SE utilizes a 998 cc (60.9 cu in) liquid-cooled in-line four, four-stroke layout. In factory specification, maximum torque reaches 114.7 Nm (84.6 lb-ft) at 11,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 76.0 x 55.0 mm (3.0 x 2.2 inches) with a 11.2:1 compression ratio.
On the scales, the Ninja H2 SX SE measures 262 kg (578 lbs) wet (curb). 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 1,481 mm (58.3 in) wheelbase engineered for balanced agility and highway composure. The 19-liter (5 US gal) fuel tank paired with a rated consumption of 5.99 L/100 km provides an estimated theoretical range of roughly 317 km (197 miles) between fill-ups.
Within MotoLibrary's Kawasaki archive, this model family spans 7 indexed model years from 2018 to 2025, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
