The long-awaited ZX-10R is Kawasaki's ultimate supersport machine, with a class-busting power-to-weight ratio and awesome muscle.
Unlike most other Kawasaki machines, the Ninja ZX-10R design started with chassis computer simulations. The engineers wanted an extremely lightweight and compact chassis that would offer superb handling and stability. The combination of a short wheelbase with a long swingarm is a configuration also seen on the Ninja ZX-RR.
An all-aluminium frame with 600-class dimensions mated to a long and highly rigid gull swingarm gives the ZX-10R category-leading handling performance on track and twisty roads.
The incredibly compact new in-line four is a showcase of advanced supersport technology. A number of considerations were made to avoid compromising the desired chassis dimensions, including use of a one-piece cylinder/crankcase, a compact rear-mounted generator and "stacked" transmission kept the high-spec power unit lightweight and compact.
Other engine features include a new fuel injection system - huge 43mm throttle bodies fitted with dual throttle valves ensure massive power output and a smooth, step-free torque curve. The hotter spark of the iridium plugs and high-voltage coils improves combustion efficiency.
Camshaft lobes and tappet surfaces feature soft-nitriding surface treatment for long wear and high-rpm reliability. Sintered aluminium valve spring retainers reduce reciprocating weight for reliable valve control at high-rpm.
Forged pistons are lightweight and very tough, for low reciprocating weight and high heat resistance. Their flat tops enable a compact combustion chamber with improved combustion efficiency. Plated cylinders are long wearing and offer excellent heat dispersion.
Intake air is routed via the central Ram Air duct and through the frame tubes to the airbox.
There's also a close-ratio transmission with a back-torque limiter clutch, and magnesium engine covers.
Sit on the ZX-10R for the first time and you will be amazed that despite its compact size and race-purpose ergonomics, it is by no means cramped. Thanks to an idealised seat/pegs/handlebar relationship and a concave tank top, which allows you to mould to the bike, the 10R puts the rider in a position to take full advantage of the engine's awesome power and the superb chassis response.
