Zephyr 750

1998 Kawasaki Zephyr 750 Technical Analysis & Specification Breakdown

At the heart of the 1998 Kawasaki Zephyr 750 naked motorcycle, Kawasaki pairs a 738 cc (45 cu in) air-cooled in-line four, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 72 HP (52.6 kW) at 9,500 rpm while maximum torque reaches 58 Nm (42.8 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 97.6 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 201 kg (443 lbs) dry, translating to a power-to-weight ratio of 0.36 HP/kg (2.79 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance.
