At the heart of the 2006 Kawasaki Ninja ZX-6RR sport motorcycle, Kawasaki utilizes a 599 cc (36.6 cu in) liquid-cooled in-line four, four-stroke layout. In factory specification, peak output is rated at 98 HP (71.5 kW) while maximum torque reaches 68.9 Nm (50.8 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 163.6 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Ninja ZX-6RR measures 164.2 kg (362 lbs) dry, translating to a power-to-weight ratio of 0.6 HP/kg (1.68 kg per horsepower). Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,400 mm (55.1 in) wheelbase engineered for quick, flickable steering geometry. The 17-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 298 km/h (185 mph).
