Positioned in Kawasaki's naked motorcycle lineup, the 1999 Kawasaki Zephyr 750 pairs a 739 cc (45.1 cu in) air-cooled in-line four, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 76 HP (55.5 kW) at 9,500 rpm while maximum torque reaches 63 Nm (46.5 lb-ft) at 7,300 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 102.8 HP per liter and a 2,200 rpm working window between peak torque (7,300 rpm) and peak power (9,500 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 Zephyr 750 measures 228 kg (503 lbs) wet (curb), translating to a power-to-weight ratio of 0.33 HP/kg (3 kg per horsepower). Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,455 mm (57.3 in) wheelbase engineered for balanced agility and highway composure. The 17-liter (4.5 US gal) fuel tank paired with a rated consumption of 7.1 L/100 km provides an estimated theoretical range of roughly 239 km (149 miles) between fill-ups, while factory top speed is listed at 203 km/h (126 mph).
