Z900 SE Performance

2025 Kawasaki Z900 SE Performance Technical Analysis & Specification Breakdown

Positioned in Kawasaki's naked motorcycle lineup, the 2025 Kawasaki Z900 SE Performance features a 948 cc (57.9 cu in) liquid-cooled in-line four, four-stroke configuration. In factory specification, peak output is rated at 122 HP (89.1 kW) at 9,500 rpm while maximum torque reaches 97.4 Nm (71.8 lb-ft) at 7,700 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 128.7 HP per liter and a 1,800 rpm working window between peak torque (7,700 rpm) and peak power (9,500 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

On the scales, the Z900 SE Performance measures 214 kg (472 lbs) wet (curb), translating to a power-to-weight ratio of 0.57 HP/kg (1.75 kg per horsepower). Rider ergonomics and chassis geometry center around a 820 mm (32.3 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 17-liter (4.5 US gal) fuel tank paired with a rated consumption of 4.8 L/100 km provides an estimated theoretical range of roughly 354 km (220 miles) between fill-ups.
