2007 Kawasaki Ninja ZX-6R


Posted on by 4

In developing the Ninja ZX-6R’s chassis, the Kawasaki engineers concentrated on designing a machine that allows high corner entry speed and high mid-corner speed.
As a result the new Ninja ZX-6R offers the power of a high-performance 600 mated with the nimble handling characteristics of a small-displacement racer - a combination that will put this bike at the head of the pack in 2007.

Designed to place its rider on the top step of the podium, the new Ninja ZX-6R sportbike elevates 600-class power and handling to the next level. Considering the stellar capabilities of last year’s ZX-6R, Kawasaki’s designers knew it would take a special combination of middleweight power and nimble handling characteristics if they were to make the next leap in middleweight performance.

To hone the incredible new machine into an exciting racetrack weapon, Kawasaki appointed a former 125cc Grand Prix racer as the ZX-6R’s chief development rider. The result is an all-new 600 capable of cornering speeds previously unknown to the middleweight class while retaining the wide spread of power that is pure Ninja.

To be quickest around the racetrack a motorcycle requires a wide powerband and plenty of over-rev. The ZX-6R’s all-new engine was redesigned from the crankcase up for the first time in ten years, leading to an ultra-high-rpm powerplant that produces more mid-range torque than any of its predecessors. The result is a fat powerband with a linear torque curve for hard-hitting acceleration across the entire rev range. The Ninja ZX-6R’s impressive over-rev capability mimics a true race bike, allowing riders to stay on the gas where lower-revving machines are forced to shift.

The Ninja ZX-6R’s all-new engine was also specially designed to reduce internal friction. That’s because low-friction engines tend to be more responsive, making it easier for the rider to modify cornering lines with minor throttle adjustments. The new engine components were also made stronger, stiffer and more compact, resulting in an engine which is about 40mm smaller in both width and length than its predecessors. This compact engine allowed the chassis designers to create a slim and compact chassis. Other racing technology includes a close-ratio cassette transmission that makes it easy to keep the Ninja ZX-6R screaming at its horsepower peak and a slipper clutch which allows quicker downshifts without upsetting the rest of the chassis.

In designing the Ninja ZX-6R’s chassis, the development team concentrated on creating a motorcycle that would make fast entry and mid-corner speeds feel easy. A compact, lightweight design allows it to maintain more cornering speed throughout the turn while entry speeds are enhanced by the slipper clutch and powerful radial-mounted front brake calipers.

Complementing this track-biased package are fully-adjustable front and rear suspension units. The entire package of frame, suspension, engine and bodywork was designed to enhance the ZX-6R’s fun-to-ride factor by offering a more exciting ride. The results are faster cornering speeds, quicker lap times and even more worried looks on the competition’s faces.

The frame and swingarm were developed with an optimized balance of rigidity, so the Ninja ZX-6R responds instantly and precisely to the rider’s every command. Mass centralization, engine mount locations and a variety of other factors were optimized to help ensure instant turn-in characteristics. Once in the turn, the Ninja ZX-6R holds a line with precision and tracks through the apex as if it were on rails.

All these features mean chassis feedback is very precise, with the ZX-6R communicating every move directly to the rider. The machine responds more precisely and predictably to control inputs and shifts in body weight. The result is a motorcycle that makes the rider feel like a part of the machine.

The new Ninja ZX-6R offers the power of a high-performance 600 Supersport racer mated with the nimble handling characteristics of a small-displacement GP machine. Let the competition compromise performance for rider-friendliness; the new ZX-6R was designed to take home trophies and set the quickest lap times, while being more exciting to ride than anything else in the middleweight sportbike category.

The Ninja ZX-6R is a pure expression of Kawasaki’s racing philosophy.

New exhaust header design contributes to improved exhaust efficiency

Six-Speed Transmission
New cassette-type transmission features a racing-style gear stack to allow easier trackside ratio changes
Close ratio transmission increases circuit performance

Racing-Style Slipper Clutch
Racing-type slipper clutch reduces chassis disturbance when making rapid downshifts. This allows the rider dedicate more attention to braking and setting up for the corner 
Optional springs, spring retainers and shims are available to fine-tune the clutch for specific track conditions

Gear Position Sensor
The convenient gear position sensor gives instant information to the rider, this is especially useful for improving consistency when testing new settings on the racetrack
The system compatible with the semi-automatic shifters (legal in AMA Supersport racing) which temporarily cut ignition to facilitate clutchless shifts at full-throttle

Lightweight Twin Spar Aluminum Perimeter Frame
Combination of pressed and cast aluminum components are welded to form the twin-spar perimeter-type frame. By combining cast and pressed pieces frame weight is kept to a minimum while still providing high strength and stability for responsive handling
Chassis features optimum center of gravity for easy roll response, this is particularly important when riding through a series of esses or returning to vertical as the rider exits a corner
 
Uni-Trak Rear Suspension
New Uni-Trak rear suspension system features pillow ball upper mount in place of the earlier bushings for a more direct feel and improved feedback
Compact frame and engine allow a longer swingarm, which makes it easier to control rear wheel powerslides
Rear shock is fully adjustable for preload, compression and rebound damping. Ride height can be adjusted by adding/removing optional 1mm shims at the upper shock mount
Equipped with a top-out spring which improves the rear wheel’s ability to follow the road surface when the rear end is light due to hard braking
Small piggyback shock reservoir is designed to save weight
 
41mm Inverted Cartridge Front Fork
New fully-adjustable 41mm inverted cartridge fork provides exceptional rigidity
Equipped with top-out springs which allow the front wheel to better follow the road surface when the front end is light due to hard acceleration
The main fork spring is located at the bottom of the fork. Because the spring is completely submerged in oil, cavitation is minimized, resulting in stable suspension performance even under demanding racetrack conditions
Stiff settings are suitable for track use

Radial Mounted Front Disc Brakes
Radial mounted four-piston, four-pad front brake calipers improve brake feel over a wider range of operation
A separate brake pad is used for each piston. One large pad tends to deform with the heat generated by hard track style riding, resulting in a loss of brake feel at the lever. Individual pads provide increased cooling efficiency and can absorb more heat without deforming so they maintain consistent brake feel lap after lap
Petal design brake discs offer excellent cooling and warp resistance
 
Aerodynamic Bodywork
New design is the most aerodynamically efficient of any Ninja sportbike available today
Light and compact projector beam headlights allow a more aerodynamic fairing
The new Ram Air duct is small but highly efficient
The exhaust system includes an under-engine resonator which allows the use of a smaller under-seat muffler. This helps to minimize drag by allowing a cleaner tail section design
Integrated front and rear turn signals reduce wind resistance
Three-piece front fender designed for aero efficiency
Different color panels create a sporty, aggressive image

Riding Position
New ultra-compact chassis places the rider in a ideal position to take advantage of the ZX-6R’s improved handling capabilities, by improving the man-machine interface
Slimmer fuel tank design makes it easier for the rider to grip the tank and seat when hanging off in a turn

the 2007 zx6r ran 86 in first when it tac out an goverened at 172 i raced it for 2 years an did stunts for 3 on the bike if the gye up top said he configured his counts at mmi go back re do it

change your sprockets to -1/+2, all ninja’s have low throttle power til around 5k rpm. I went to MMI and calculated it up the maximum speed for a stock zx6r in 1st gear is 74.52 and top speed of 155.58. doesnt matter how much power it has the gears physically wont let it go any faster. a +1/+3 would do 180 but be slow getting there

Any body know what to do to give my 2007 ZX6r more low end torque. I have a two brothers slip on exhaust and a power commander III USB mapped for the exhaust?

I own this bike, it has got to be the fastest 600 out there. It’ll do 90 in 1st gear, that ends up bein a 180 topspeed!!! its quick as !
