2006 Kawasaki Ninja ZX-6 R Technical Analysis & Specification Breakdown
Built around Kawasaki's sport motorcycle platform, the 2006 Kawasaki Ninja ZX-6 R relies on a 636 cc (38.8 cu in) liquid-cooled in-line four, four-stroke powerplant. In factory specification, peak output is rated at 130 HP (94.9 kW) at 14,000 rpm while maximum torque reaches 68.9 Nm (50.8 lb-ft) at 11,550 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 204.4 HP per liter and a 2,450 rpm working window between peak torque (11,550 rpm) and peak power (14,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Ninja ZX-6 R measures 164.2 kg (362 lbs) dry, translating to a power-to-weight ratio of 0.79 HP/kg (1.26 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 17.03-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 264 km/h (164 mph).
