At the heart of the 1989 Kawasaki GPX 600 (ZX600C2) sport motorcycle, Kawasaki relies on a 592 cc (36.1 cu in) in-line four, four-stroke powerplant. In factory specification, peak output is rated at 85 HP (62 kW) at 11,000 rpm while maximum torque reaches 58 Nm (42.8 lb-ft) at 9,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 143.6 HP per liter and a 2,000 rpm working window between peak torque (9,000 rpm) and peak power (11,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the GPX 600 (ZX600C2) measures 180 kg (397 lbs) dry, translating to a power-to-weight ratio of 0.47 HP/kg (2.12 kg per horsepower). Rider ergonomics and chassis geometry center around a 755 mm (29.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,425 mm (56.1 in) wheelbase engineered for balanced agility and highway composure. The 16-liter (4.2 US gal) fuel tank paired with a rated consumption of 5 L/100 km provides an estimated theoretical range of roughly 320 km (199 miles) between fill-ups.
