Ninja H2 SX

2023 Kawasaki Ninja H2 SX Technical Analysis & Specification Breakdown

Positioned in Kawasaki's sport touring motorcycle lineup, the 2023 Kawasaki Ninja H2 SX 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 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 H2 SX measures 261.7 kg (577 lbs) wet (curb), translating to a power-to-weight ratio of 0.87 HP/kg (1.15 kg per horsepower). Rider ergonomics and chassis geometry center around a 836 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 18.93-liter (5 US gal) fuel tank paired with a rated consumption of 8.53 L/100 km provides an estimated theoretical range of roughly 222 km (138 miles) between fill-ups.
