2004 Kawasaki Z 1000 Technical Analysis & Specification Breakdown
At the heart of the 2004 Kawasaki Z 1000 naked motorcycle, Kawasaki features a 953 cc (58.2 cu in) liquid-cooled in-line four, four-stroke configuration. In factory specification, peak output is rated at 127 HP (92.7 kW) at 10,000 rpm while maximum torque reaches 95.6 Nm (70.5 lb-ft), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 133.3 HP per liter, 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 221 kg (487 lbs) wet (curb), translating to a power-to-weight ratio of 0.57 HP/kg (1.74 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, while factory top speed is listed at 248 km/h (154 mph).
