2004 Kawasaki Z 750 Technical Analysis & Specification Breakdown
At the heart of the 2004 Kawasaki Z 750 naked motorcycle, Kawasaki relies on a 748 cc (45.6 cu in) liquid-cooled in-line four, four-stroke powerplant. In factory specification, peak output is rated at 110 HP (80.3 kW) while maximum torque reaches 7.6 Nm (5.6 lb-ft), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 147.1 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Z 750 measures 195 kg (430 lbs) dry, translating to a power-to-weight ratio of 0.56 HP/kg (1.77 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 1,425 mm (56.1 in) wheelbase engineered for balanced agility and highway composure. The 18-liter (4.8 US gal) fuel tank paired with a rated consumption of 5.21 L/100 km provides an estimated theoretical range of roughly 345 km (214 miles) between fill-ups, while factory top speed is listed at 233 km/h (145 mph).
