After four years of offering the 636cc ZX-6R for street use and the 599cc ZX-6RR for displacement-restricted racing classes, in 2007, Kawasaki offered only one version of the ZX-6R with a 599cc displacement.
Unlike the previous engine that was built from the same basic design, the new powerplant was redesigned from the crankcase up with a stacked gear arrangement where the crankshaft, primary drive, and countershaft were placed in a triangular shape for a shorter and more compact design.
In addition, the bike's frame, swingarm, suspension, brakes, and body were completely redesigned with just a few parts shared from the previous model and carried over to the 2008 model with just color scheme changes.
The bike featured an incredible power-to-weight ratio and race-oriented performance with track-tuned handling topped by a new aggressive aerodynamic styling.
In the power department, the 2007 Kawasaki Ninja ZX-6R took its thrust from a 599cc four-stroke four-cylinder liquid-cooled engine with a lightweight, compact, and narrow design that provided excellent ground clearance and featured lighter, stronger forged pistons that were more heat resistant than the cast ones.
As for the power figures, the Ninja ZX-6R delivered an output power of 125 hp with a peak at 14,000 rpm and 66 Nm (49 lb-ft) of torque available at 11,700 rpm. Combined with a dry weight of 167 kg (368 lbs) and a six-speed manual transmission, the bike reached a top speed of 252 kph (156 mph).
