2025 Kawasaki Z H2 SE Technical Analysis & Specification Breakdown
Positioned in Kawasaki's naked motorcycle lineup, the 2025 Kawasaki Z H2 SE features a 998 cc (60.9 cu in) liquid-cooled in-line four, four-stroke configuration. In factory specification, peak output is rated at 197.3 HP (144 kW) at 11,000 rpm while maximum torque reaches 137 Nm (101.1 lb-ft) at 8,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 197.7 HP per liter and a 2,500 rpm working window between peak torque (8,500 rpm) and peak power (11,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Z H2 SE measures 240 kg (529 lbs) wet (curb), translating to a power-to-weight ratio of 0.82 HP/kg (1.22 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 1,455 mm (57.3 in) wheelbase engineered for balanced agility and highway composure. The 19-liter (5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
