Z 1000

2003 Kawasaki Z 1000 Technical Analysis & Specification Breakdown

Engineered by Kawasaki for the naked motorcycle segment, the 2003 Kawasaki Z 1000 features a 953 cc (58.2 cu in) in-line four, four-stroke configuration. In factory specification, peak output is rated at 125 HP (91.2 kW) at 10,000 rpm while maximum torque reaches 95.7 Nm (70.6 lb-ft) at 8,000 rpm. With a specific output of 131.2 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 Z 1000 measures 198 kg (437 lbs) dry, translating to a power-to-weight ratio of 0.63 HP/kg (1.58 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 1,420 mm (55.9 in) wheelbase engineered for balanced agility and highway composure. The 18-liter (4.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
