From Kawasaki's press material:

Mount a fuel-injected NINJA ZX-9R-based engine in a lightweight chassis, equip it with state-of-the-art Ninja running gear, and wrap in the slinkiest bodywork this side of a Milan fashion show and what do you get? The all-new 2003 Kawasaki Z1000 motorcycle. Kawasaki is taking the "naked" category to an all-new level by introducing the world's first Super Naked motorcycle. In addition to a visual impact no other machine can match, the ZX-9R-based engine gets a displacement boost to 953 cubic centimeters producing heaps of gutsy torque resulting in hard-charging performance.

The Z1000 flaunts aggressive style and backs it all up with a sleek, high-performance engine. An in-line-four, DOHC 16-valve engine produces tractable power delivery for quick acceleration in any rpm range. The lightweight, all-aluminum cylinder block, with chrome composite plated lining for wear resistance and superior heat dispersion are features borrowed from the Kawasaki Ninja sportbike line. The new aluminum cylinder head is designed to run on regular gas while cam timing and profile are designed for abundant low- and mid-range power. In addition, a new front cam-chain guide is lighter. Performance and appearance meet again at the new horizontal intake ports to suit traditional styling.

Digital fuel injection utilizing 38mm throttle bodies and sub-throttle valves promote smooth engine operation. The advanced system provides excellent engine response and power with less fuel consumption. The high-speed 32-bit digital ignition provides precise engine management and enhances the fuel injection system.

Keeping the entire engine cool is a large-area radiator with an electric fan that maintains operating temperatures at the optimum level. Simultaneously, a liquid-cooled oil cooler helps keep the six-speed transmission operating at maximum performance.

Part of the Z1000's allure lies in the four stainless steel mufflers that are heat-treated to an attractive golden color. Enhancing its appeal is the KLEEN (Kawasaki Low Exhaust Emissions) catalyzer system that helps keep exhaust emissions that flow through the quad mufflers environmentally friendly. In select markets, an additional honeycomb catalyzer system reduces emissions even further.

The Z1000's engine is mounted in a rigid, yet lightweight diamond frame with thin-walled tubes, which contributes to responsive handling performance. The engine itself is mounted as a stressed member of the frame, adding an unflappable feel to the chassis. Plus, a detachable right front-top engine mount eases maintenance.

At the front of the frame, an inverted fork with 41mm tubes deliver exceptional stability and steering performance. To meet the requirements of different riding conditions, the fork is preload and rebound adjustable. In addition, the fork offset has been reduced to improve handling and provide a fluid ride.

On the rear, an extruded-aluminum swingarm features a hexagonal structure with ribbing for reduced weight and exceptional rigidity. Attached to the swingarm is Kawasaki's bottom link UNI-TRAK system, equipped with a nitrogen gas-charged rebound adjustable shock. For adjusting and ease of maintenance, the shock is equipped with a piggyback reservoir and a rebound damping adjustment. All shock settings are modified to match the new chassis.

Contributing to the Z1000's superb handling characteristics are 17-inch rims and radial tires, borrowed from the ZX-9R.. The tires offer excellent traction, while the rims look great with a polished finish that contrasts nicely with painted hubs and spokes. Front brakes are dual semi-floating 300mm discs gripped by lightweight four-piston calipers from the ZX-9R, while the rear brake caliper holder is also designed for low weight and mounts directly to the swingarm, negating the need for an independent brake torque-rod.

To the naked eye, the Z1000 can best be defined by the sexy lines and stylishly crafted bodywork and ergonomics. The seat cowl with LED taillight, swingarm-mounted inner fender and front fender are all designed to give the Z1000 an aggressive, sporty image. The galvanized steel fuel tank is slender and helps create a seating position that is comfortable allows the rider to mold to the machine naturally. Meanwhile, the bikini cowl with dual, multi-reflector headlights accentuates the bike's provocative lines.

The slinky cowl covers and protects a lightweight, compact instrument cluster featuring a bar-type LCD tachometer and digital LCD speedometer. In addition to a digital temperature gauge, clock, tripmeter and fuel gauge is a comprehensive range of indicator lamps.

The Z1000 takes "naked" to a new level with high performance, responsive handling and knockout good looks. The Z1000 didn't move to the head of the class, it created a class of it's own - the Super Naked.
