Positioned in Kawasaki's sport motorcycle lineup, the 1991 Kawasaki ZXR 250c utilizes a 249 cc (15.2 cu in) liquid-cooled in-line four, four-stroke layout. In factory specification, peak output is rated at 45 HP (32.8 kW) at 16,000 rpm while maximum torque reaches 24 Nm (17.7 lb-ft) at 11,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 180.7 HP per liter and a 5,000 rpm working window between peak torque (11,000 rpm) and peak power (16,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the ZXR 250c measures 162 kg (357 lbs) wet (curb), translating to a power-to-weight ratio of 0.28 HP/kg (3.6 kg per horsepower). The 15-liter (4 US gal) fuel tank paired with a rated consumption of 5 L/100 km provides an estimated theoretical range of roughly 300 km (186 miles) between fill-ups, while factory top speed is listed at 215 km/h (134 mph).
