2018 Kawasaki Ninja H2 R Technical Analysis & Specification Breakdown

At the heart of the 2018 Kawasaki Ninja H2 R sport motorcycle, Kawasaki pairs a 998 cc (60.9 cu in) liquid-cooled in-line four, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 310 HP (226.3 kW) at 14,000 rpm while maximum torque reaches 165 Nm (121.7 lb-ft) at 12,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 310.6 HP per liter and a 1,500 rpm working window between peak torque (12,500 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 H2 R measures 216.1 kg (476 lbs) wet (curb), translating to a power-to-weight ratio of 1.43 HP/kg (0.7 kg per horsepower). Rider ergonomics and chassis geometry center around a 830 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.
