Kawasaki Z: Bringing You the World’s Coolest Streetbikes Since 1973 With this latest in a long line of naked Kawasaki streetbikes, we threw out the old rules and started with a clean sheet, drawing upon more than 35 years of experience in giving the people what they want. If the new Z1000 knocks your eyeballs out, that’s exactly what we had in mind. Even more important, though, is the feeling this one provides every time you twist the throttle.
A sharp new front cowl sloped back at an acute angle highlights the Z1000’s new nose, followed by a tilting instrument panel, visible through an orange lens, that can be angled to suit rider preference. Just below that a long, narrow headlight represents Kawasaki’s first use of a line-beam unit. Following the lines rearward, the eyes will next encounter a dynamically designed steel gas tank, flared on the sides to let you grab it with your knees, and trim at the rear for a snug fit. The seat’s low and narrow at the front to make ground contact easy, and it flows beautifully rearward to end in a futuristically retro LED taillight behind a red lens.
At the heart of every naked bike is its engine. We didn’t just bolt it into that frame for solid handling, we did it so you won’t forget what you’re riding: You’ll definitely feel those 1,043 cubic centimeters of fuel-injected Kawasaki four-cylinder every time you twist the throttle. A secondary balance shaft eliminates excess vibes, but on this bike, a little bit of character is designed in. In the same spirit, the bike’s cool air system uses ducts just ahead of the fuel tank to usher air into the airbox, a placement that lets the rider savor the bold sound of screaming air being sucked into the engine’s downdraft intakes.
The Z1000’s four-cylinder uses a longish stroke—56mm—to make the most impact in the rpm range most used by naked bike riders. Long-stroke engines keep intake air velocity up for maximum midrange power whatever the displacement. From nearly any rpm, rolling the Z1000’s throttle open provides the kind of instant gratification most sportbikes just can’t quite muster. Having said that, this engine also spins up noticeably faster from about 7000 rpm upwards, with a silky smooth, highly intoxicating response.
The Z1000 clearly surpasses the dynamic performance of its predecessors, thanks to a new quick-revving 1,043cc inline-four cylinder engine, and an all-new quick-steering aluminium chassis connected to an all-new horizontal rear suspension design. Though it offers true sportbike handling; the Z1000’s comfortable, upright riding position mean it remains a practical transportation tool, even as the dramatic howl from its new cold-air intake raises hairs on the back of its rider’s neck.
Features And Benefits
- Liquid-cooled, DOHC, 16-valve 1,043cc inline-four offers greater torque and a stronger top-end rush than previous Z1000 models
- Bore and stroke of 77.0 x 56.0 mm were chosen to achieve the desired engine character -strong in the everyday rpm range most used by naked super bikes
- 38mm downdraft throttle bodies allow intake air to travel to the engine in the shortest possible distance
- Oval sub-throttles help keep the engine slim – a good thing since the throttle bodies are positioned between the rider’s knees
- Soft rev limiter provides good overrev; power doesn’t drop off suddenly at high rpm
- Crankshaft and transmission shafts are arranged in a straight line instead of a triangular layout, to maintain the design from the previous Z1000 – a design that offers the best look for a naked model
- The crankshaft was lowered to allow for a longer stroke without adding engine height
- A secondary balancer, driven off a gear on the sixth web of the crankshaft, eliminates excess vibration
Cool Air System
- The intake system routes cool air to the airbox from ducts above the radiator shrouds, minimizing performance loss due to heated intake air
- Positioning the ducts close to the rider allows the intake sound to be enjoyed by the rider
- A resonator inside the airbox reduces noise at low rpm, and enhances intake sound at high rpm
- The exhaust system features a 4-into-2-pre-chamber-into-2 layout. Silencer end-caps maintain the quad-style image
- Main and pre-catalyzers ensure emissions are clean
- Thanks to the under-engine pre-chamber, silencer volume could be reduced. The silencers are also lighter. Overall exhaust system weight is about the same, but the new system offers much better mass centralization and contributes to a lower center of gravity
- Slim-type fuel pump features an integral fuel gauge
- With revised fuel tank design and the slim-type fuel pump, dead volume inside the tank is minimized; fuel capacity is 4.1 gallons.
All-New Aluminum Backbone Frame
- An aluminum backbone frame designed specifically for the Z1000, and similar in concept to the frame of the Ninja ZX-10R, allows a narrow construction that is easy to grip with the knees
- Lightweight and highly rigid, the frame uses the engine as a stressed member, for a firm, planted feeling and enhanced stability
- Frame is tuned to transmit the ideal level of engine feedback directly to the rider
- The frame’s five-piece construction consists of steering stem, left and right main frames, and two cross pieces. The two main frame components have open C-shaped cross sections
- As much as possible, welds were eliminated for simplicity and appearance. The frame beams and swingarm brackets are now single die-cast pieces
- The new frame uses four engine mounts; three mounts are rigid, the upper rear crankcase mount is rubber
- The rear sub-frame is a three-piece aluminum die-casting construction, light, strong and good for mass centralization – The sub-frame is an example of form and function combined, negating the need for side covers and allowing underseat narrowness for a shorter reach to the ground.
All-New Horizontal Rear Monoshock – New rear suspension positions the shock unit and linkage above the swingarm where it’s less exposed to exhaust heat and contributes to mass centralization
- Visible from the outside, the horizontal monoshock contributes to the aggressive appearance of the new Z1000
- Linkage characteristics are the same as those of a standard UNI-TRAK rear suspension: Wheel movement versus shock stroke is the same ratio
- The shock features rebound damping and spring preload adjustability
Fully Adjustable Front Fork
- The Z1000′s 41mm inverted fork is adjustable for compression damping, rebound damping and spring preload – and it’s protected from harm by a cool-looking shroud
- Settings are designed for both sporty back road performance and excellent comfort on the street
Handlebar, Grips and Footpegs
- The tubular handlebar is rigid-mounted, contributing to sharp, direct handling
- A wide, flat bend handlebar offers a design similar to those on off-road bikes, for excellent control
- Tapered-type grips, like those used on supersport models, offer more direct feel
- Ninja ZX-10R-style footpegs with knurling offer good grip, direct feel and control and no-nonsense looks
- The passenger footpeg brackets incorporate convenient luggage hooks
- The Z1000′s 300mm front petal brake discs are gripped by opposed four-piston radial-mount calipers. (Caliper piston size is 4×30 mm)
- A radial-pump front brake master cylinder contributes to the superb control and feel offered by the new calipers – The rear brake is a single piston, pin-slide caliper gripping a 250mm petal disc. The caliper is mounted below the swingarm, and located by a torque rod.
The new Z1000 takes the aggressive styling of its predecessor a step forward. From the sharply sloped front cowl design made possible with the slim new line-beam headlamp, to the minimalist tail section, the new Z1000 presents a very condensed, mass-forward image. This dynamic design is reinforced by the front fork covers and wide shrouds adorned with intakes for the new Cool Air system. Where its predecessor formed the image of an athlete poised to explode out of the blocks, the new Z1000 gives the appearance of a dangerous predator feigning sleep – though no less ready to leap forward without a moment’s hesitation.
Condensed, Mass-forward Image for Dynamic Design
Sharp front cowl slopes back at an acute angle, contributing to the aggressive design and the image of a low, forward-located centre of gravity.
- Wider and moved slightly further and higher. New position contributes to the rider’s freedom of movement.
- Fat-type handlebar contributes to tough appearance.
- Lowered approximately 5 mm. Slightly narrower thanks to the new frame; this contributes to the rider’s freedom of movement.
- Aluminum footpegs from the Ninja ZX-10R with machined edges contribute to the direct feel.
- Radial-mount calipers and a radial-pump master cylinder deliver superb braking performance and precise brake control.
Front suspension – Compression damping adjustability added. Settings chosen to deliver light handling.
The 2011 Ninja ZX-14, which comes to challenge Suzuki’s coveted Hayabusa, is powered by a 1,352cc liquid-cooled, DOHC, four valve per cylinder, inline-four engine. The power is channeled through a hydraulic clutch and six speed transmission, down to the 190/50 ZR17 rear tire. The exact horsepower and torque figures of the Ninja ZX-14 are irrelevant, but a track day will tell you anything there is to know. As for the brakes, what we do know is that each piston in the calipers has its own brake pad, which increases cooling efficiency and decreases the chance deforming due to heat.
No company knows more about in-line fours than Kawasaki. From the early Z-1 to our factory MotoGP bikes, our knowledge about the in-line four-cylinder engine is unsurpassed. The virtues of this design are many: powerful, smooth running and very compact, if it’s a Kawasaki superbike, it has to be an in-line four. Each component of this amazing engine was thoroughly developed to deliver the perfect balance of power, torque, and ridability. Twisting the throttle on the ZX-14 gives the kind of response you would expect from a large bore machine; a seamless spread of awesome torque, right ’round the dial.
The Ninja ZX-14 runs Kawasaki’s exclusive aluminum monocoque frame. Rock steady at speed, and offering responsive handling characteristics, this advanced chassis design strikes an ideal balance between sport riding, and high-speed running on the highway. Our engineers made full use of the design freedom given to them by the engine’s compact size. The engine’s position forward in the frame, the wheelbase and front/rear wheel weight balance were all carefully chosen to achieve both high-speed stability and responsive handling. Aluminum monocoque frame represents a further evolution of the frame first used on Kawasaki’s KR500 racer then in production on the Ninja ZX-12R. This advanced design makes possible a very slim, compact package.
Formidable front brake performance is further enhanced with a radial-pump master cylinder that offers superb feel at the lever. Use of four individual brake pads promotes even heat distribution across each pad virtually eliminating fade due to pad warpage at high temperatures.Rearbrake features 250mm, drilled, petal style rotor and 2-piston callipers for additional stopping power and improved braking feel. Newly designed wheels feature centre ribs that are slightly offset so that tire balance weights can be located at the wheel centreline.
In spite of the ZX-14′s awesome performance, the machine is surprisingly non-intimidating. This is due as much to the seamless power delivery, as it is to the smooth ride and its rider-friendly ergonomics. On the ZX-14, the typical weekend jaunt leaves the rider refreshed and invigorated. Despite its long and low appearance, the ZX-14 offers a very relaxed sport riding position. Compact without being cramped, the bars are positioned so that riders do not have to stretch to reach them. Low-set footpegs give ample legroom. The low seat height and narrow seat front make it easy to reach the ground when stopped at lights.The narrow engine, monocoque frame, and waisted fuel tank make it easy to keep knees comfortably close together when riding. A depression in the fuel tank cover facilitates tucking in behind the screen.
Aerodynamics & Styling
The ZX-14 exudes an aura of power and assurance found only in the world’s most powerful machines. As befits its flagship status, the ZX-14 offers a combination of avant garde design, meticulous craftsmanship and attention to detail. Whether parked in front of a café or zooming effortlessly down the highway, this is a machine people will notice. The ZX-14′s bodywork gives it extremely long and low styling. The front cowl extends well over the front wheel and the fairing almost hides the front wheel. All the lines of the bike move from front to rear, giving the bike an impression of speed even when it standing still.
The ZX-14′s multifunctional aerodynamics package reduces drag, adds stability at highway speeds and keeps you out of the wind when sport riding in the hills.Raised “Kawasaki” and model emblems contribute to the classy styling. Long front fender with aerodynamic side wings contributes to the ultra high speed potential of the ZX-14.
A small under-cowl forward of the rear wheel contributes to the bike’s flowing lines. This under-cowl is removed when fitting the optional center stand. LED tail lamp features a unique “V” design. This will be the most common view of the ZX-14 on the move. Front and rear turn signals are integrated into the fairing and rear cowl. Clear signal lenses with orange bulbs contribute to the high quality appearance.
