"All-out sportbike performance and aggressive styling" is the best way to sum up the all-new 2003 Kawasaki NINJA® ZX-6R sportbike. Based on the limited edition NINJA® ZX-6RR, the radical new ZX-6R boasts a redesigned engine and crankcase with 37 extra cubic centimeters of displacement, an electronic fuel injection system and an all-new chassis. These new features, plus a host of additional design changes, are sure to leave the competition hung out to dry.

Powering the ZX-6R is a liquid cooled, DOHC, 16-valve, 636cc, four-cylinder engine tuned for optimum performance, especially in the high rpm ranges. Engine modifications such as reducing the cylinder head height by 10mm, reshaping the camshaft oil supply line, shortening the cylinder 5mm, and shortening the intake valves by 10mm, result in a lightweight, more compact engine that produces more muscle all around. The ZX-6R's six-speed transmission shifts smoother due to new shift cam shape, spring loads and shift lever ratio. Plus, new gear ratios tighten up the clearances between third and sixth gear.
