Engineered by Kawasaki for the naked motorcycle segment, the 2019 Kawasaki Z1000SX relies on a 1043 cc (63.6 cu in) liquid-cooled in-line four, four-stroke powerplant. In factory specification, peak output is rated at 140.8 HP (102.8 kW) at 10,000 rpm while maximum torque reaches 111 Nm (81.9 lb-ft) at 7,300 rpm. With a specific output of 135 HP per liter and a 2,700 rpm working window between peak torque (7,300 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 Z1000SX measures 221 kg (487 lbs) wet (curb), translating to a power-to-weight ratio of 0.64 HP/kg (1.57 kg per horsepower). Rider ergonomics and chassis geometry center around a 815 mm (32.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,435 mm (56.5 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.
