Kawasaki are introducing their long awaited entry into the litre-class with the new Ninja ZX-10R, and they are claiming it has been worth the wait.

Kawasaki are claiming the highest power-to-weight ratio in the class but at the same time not yet releasing details of the claimed dry weight of their new machine and are also not yet quoting horsepower figures. 

The following is a list of claims Kawasaki are making for their new open class blaster.

• Best Power-to-Weight Ratio in its Class – Unbeatable combination of high power, brilliant throttle response and low exhaust emissions from a liquid-cooled, DOHC, 16-valve, In-Line Four featuring a sophisticated automotive-style fuel injection system with 43 mm throttle bodies, dual throttle valves and fine-atomising injectors. Light weight care of an incredibly compact engine package, and a compact all-aluminium frame. Newly designed lightweight wheels also contribute to weight savings that result in a litre-class machine with the weight and dimensions of a 600.

• Race-Oriented Performance – The combination of a short wheelbase with a long swingarm gives the ZX-10R incredibly nimble handling performance. The concave tank top and an idealized relationship between pegs, handlebars and seat, creates an aggressive, compact riding position. Close-ratio transmission, back torque limiter, radial mount calipers, petal disc brakes and fully adjustable suspension are also all designed with the sole purpose of racing in mind.

• Aggressive Styling – Visually expressive of Kawasaki’s supersport DNA, the ZX-10R’s flowing, edge-driven lines express the machine’s amazing performance and unsurpassed power-to-weight ratio.

Engine

* Liquid-cooled, DOHC, 16-valve, 998 cm3 engine has a bore and stroke of 76 x 55 mm.
* Huge 43 mm throttle bodies fitted with dual throttle valves ensure massive power output and a smooth, step-free torque curve.

* The all-aluminium twin-beam frame is a composite structure of castings and pressings. Lightweight and very compact, it features a short wheelbase and a long swingarm.
* The frame’s thin walled die castings are a mere 2.5 mm thick for maximum strength with minimum weight.
* Use of a cast cross pipe results in fewer parts and less welding.
* Frame rails run over the engine to give it a width on par with current 600-class bikes.
* Front fork features many aluminium internal components to reduce weight.
* Lightening holes in the top triple clamp contribute to the machine’s overall light weight.
* Forged aluminium handlebars are gun-drilled for light weight.
* Other lightweight chassis components include dual aluminium steering stem nuts, lightweight pop nuts for the bodywork and aluminium rear-suspension bearing arm sleeves and wheel side collars.
* Lightweight new front and rear wheels feature “H” cross-section spokes. The unique, 6-spoke design permits use of thinner rims, for significant weight savings. Wheels are significantly lighter than those used on the ZX-9R.
* Like the ZX-RR, the 10R chassis minimises the distance between the steering stem and swingarm pivot to create a compact, responsive package.
* Massive braced swingarm delivers the rigidity needed for a machine with the ZX-10R’s horsepower. Long swingarm design reduces the engine’s leverage on the rear suspension, for excellent suspension action and superb road holding qualities. Specially configured for high torsional rigidity and more flexible lateral rigidity, this “balanced flex” contributes significantly to the 10R’s brilliant handling qualities. Amazingly lightweight, the swingarm weighs about the same as the ZX-6R swingarm.

Ergonomics

* The 10R’s riding position was developed based on computer simulation and exhaustive rider feedback.
* Thanks to the narrow width of the frame rails, which run over the engine, the rear of the tank could be made very narrow, allowing the rider to grip the bike with his legs.
* Because the air cleaner is flush with the top of the frame rails, the fuel tank bottom can be made flat, significantly increasing fuel tank capacity without increasing overall tank size.
* The top surface of the fuel tank is concave, making it easier to tuck in behind the fairing and increasing rider comfort during high-performance riding.
* An ideal relationship between pegs, seat and handlebars result in a naturally aggressive riding position.

Brakes

* The Ninja ZX-10R is the first supersport bike to feature petal brake discs. This unique disc shape improves cooling and helps prevent disc warp. It is also lighter than conventional discs.
* Front discs are 300 mm. Radial 4-pot opposed piston calipers deliver impressive stopping performance with excellent feel at the lever.
* The lightweight 220 mm rear petal disc is operated by a lightweight single-piston caliper.
 

* Highly rigid 43 mm inverted fork is fully adjustable and features settings that are biased towards track riding.
* Both front and rear suspension are fitted with top-out springs for stable suspension performance. Because the top-out springs regulate suspension elongation, the rider will also experience less nose dive feel under heavy braking after hard acceleration, as well as greater stability when getting back on the gas after hard braking.
* Linkage-equipped rear gas shock with reservoir is fully adjustable.
* Lightweight aluminium suspension linkage reduces chassis weight and contributes to the responsive rear suspension action.
* Rear ride height is shim-adjustable.

Bodywork/Styling

* Highly compact front cowl incorporates a central Ram Air duct and features a frontal area smaller than that of the ZX-6R.
* Multi-reflector headlamp is compact and is located very low. Lighting performance is first rate.
* Aerodynamic mirrors look great and offer high visibility.
* Seamless fuel tank design enhances the 10R’s high-quality look and feel.
* 3-piece front fender is highly aerodynamic and contributes to the front end’s light appearance.
* European models feature front turn signals stylishly integrated in the bodywork for improved aerodynamics. Rear turn signals are extremely compact and feature a new conical design.
* Attractive inner fender design follows the lines of the swingarm and contributes to laminar flow of hot air around the rear wheel.
* Compact rear flap contributes to the 10R’s slim appearance. It is mounted directly to the sub-frame for added strength.
* Flush-surface LED tail light curves up slightly over the top of the seat cowl, making the 10R very visible to the drivers of high vehicles.
* Multi-piece tail cover allows an ultra-thin design as well as easy maintenance. Removing the top two pieces allows complete access to the top.
* Frame is finished in flat black to enhance its aggressive, racy image.
* Robot welding is used for high quality and a superior finish.
* Optional single seat cover can replace the tandem seat for an even more aggressive image.
