2000 Kawasaki ZXR 400 Technical Analysis & Specification Breakdown

Positioned in Kawasaki's sport motorcycle lineup, the 2000 Kawasaki ZXR 400 relies on a 398 cc (24.3 cu in) engine powerplant. In factory specification, peak output is rated at 65 HP (47.4 kW) at 13,000 rpm while maximum torque reaches 36 Nm (26.6 lb-ft) at 12,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 163.3 HP per liter and a 1,000 rpm working window between peak torque (12,000 rpm) and peak power (13,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.

On the scales, the ZXR 400 measures 159 kg (351 lbs) dry, translating to a power-to-weight ratio of 0.41 HP/kg (2.45 kg per horsepower). Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops.
