KAWASAKI Ninja ZX-6RR (2004-2005) Specs, Performance & Photos

In 2005, the Japanese motorcycle manufacturer launched the Kawasaki Ninja ZX-6RR, the racing-homologated sibling of the ZX-6R, which came in a limited production number and was designed for track performance.

The bike featured all-new aerodynamic bodywork with ram air intake, a GP-style swingarm, an under-seat-mounted exhaust system, six-spoke wheels, petal disc rotors, an inverted fork, and a powerful engine.

The Ninja ZX-6RR set new standards of performance for the middle-weight class with its new engine that included new cylinders, a new cylinders head, and 38 mm oval-shaped sub-throttle valves fed by twin injectors and a redesigned ram air intake system.

Powered by a 599cc four-stroke four-cylinder liquid-cooled engine, the 2005 Kawasaki Ninja ZZX-6RR delivered an output power of 118 hp with a peak at 13,200 rpm and 64 Nm (48 lb-ft) of torque available at 12,000 rpm.

In addition, the model featured a more durable, smoother-shifting six-speed manual transmission with a multi-place wet back-torque limiter clutch and ratios similar to those of the 2004 racing kit transmission, designed for maximum track performance.

For suspension, the bike packed a 41 mm adjustable inverted cartridge fork on the front and a bottom-link Uni-Trak adjustable shock absorber on the rear, while the braking performance was achieved by two 300 mm petal discs with four-piston calipers on the front and one 220 mm petal disc with a single-piston caliper on the rear.
