Positioned in Kawasaki's sport motorcycle lineup, the 2023 Kawasaki Ninja 1000SX Performance utilizes a 1043 cc (63.6 cu in) liquid-cooled in-line four, four-stroke layout. In factory specification, peak output is rated at 142 HP (103.6 kW) at 10,000 rpm while maximum torque reaches 111 Nm (81.9 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 136.1 HP per liter and a 2,000 rpm working window between peak torque (8,000 rpm) and peak power (10,000 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 Ninja 1000SX Performance measures 235 kg (518 lbs) wet (curb), translating to a power-to-weight ratio of 0.6 HP/kg (1.65 kg per horsepower). 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 1,440 mm (56.7 in) wheelbase engineered for balanced agility and highway composure. The 17-liter (4.5 US gal) fuel tank paired with a rated consumption of 5.8 L/100 km provides an estimated theoretical range of roughly 293 km (182 miles) between fill-ups.
