2007 Kawasaki Ninja ZX-6R
2007 Ranges | 2006 Ranges | 2005 Ranges | 2004 Ranges
Born for the track, the new Ninja ZX-6R was designed to put its rider on the top
step of the podium. What Kawasaki's development team found was needed to
enable the new 6R to make a huge leap forward in circuit potential was a
consummate blend of the power characteristics of a fully tuned 600 Supersport
machine and the nimble handling characteristics of a lightweight, smalldisplacement
GP-style racer. To incorporate this lightweight-class handling
philosophy into the new 6R, Kawasaki appointed a former 125cc WGP racer as
the Ninja ZX-6R's chief development rider. The results? A meaty mile-wide
powerband. Cornering prowess previously unseen in the middleweight class.
And a man-machine synchronicity that yields instantaneous response to the
rider's slightest command. Then we loaded in features usually reserved for our
limited-edition Ninja ZX-6RR. More so than any Ninja ZX-6R - or 6RR - to date,
this evolution represents Kawasaki's ideal 600cc-class circuit machine. The
ultimate middleweight track tool, the new Ninja ZX-6R sets the standard to
follow in 2007.
Featuring an all-new engine - completely redesigned from the cases up for the first
time in ten years - and all-new chassis, the Ninja ZX-6R was designed to dominate
on the track. Let other models talk about rider-friendliness - this bike was designed
to take home the trophies, set the quickest lap times and be more exciting to ride
than anything else in its category. The Ninja ZX-6R - a pure expression of
Kawasaki's racing philosophy.
Super-Responsive Power Across The Rev Range
To be quick around a racetrack a bike needs a wide powerband with plenty of overrev.
The Ninja ZX-6R's all-new ultra-high-rpm engine churns out way more mid-range
torque than its predecessors. The result is a nice fat powerband with a linear power
curve, for hard-hitting acceleration across the rev range. Like a true racebike, the
Ninja ZX-6R's over-rev characteristics are equally impressive, allowing riders to stay
on the gas longer, while weaker bikes are forced to shift. Other racing technology
includes a close-ratio cassette transmission that makes it easy to keep the Ninja ZX-
6R screaming at peak efficiency.
High Cornering Speed - The Secret To A Quick Lap Time
In designing the Ninja ZX-6R's chassis, the development team concentrated on
creating a chassis that allows high corner entry and mid-corner speed. Like a bike
with much smaller displacement, the Ninja ZX-6R's compact, lightweight chassis
allows it to maintain its cornering speed throughout the turn - this is what makes it
so quick. Cornering speed control is further enhanced by a perfectly balanced
combination of slipper clutch and powerful radial-mounted brake calipers.
Complementing this track-biased package are fully adjustable front and rear
suspension units. The results are a higher average cornering speeds, quicker lap
times and no competition.
All-New, Ultra-Compact, Low-Friction Engine
The Ninja ZX-6R's all-new engine was specially designed for ultra-low friction. Lowfriction
engines deliver highly responsive throttle control, making it easier for riders to
adjust their speed and line while cornering. To reduce frictional loss, engine
components were made stronger, stiffer and more compact. The resulting engine is
about 40 mm smaller in width and length than its predecessors. This compact engine
contributes significantly to the Ninja ZX-6R's overall slim and compact chassis.
The frame and swingarm were developed with an ideal stiffness balance, so the
Ninja ZX-6R responds instantly and precisely to the rider's every command. Mass
centralisation, engine mount locations and a variety of other factors were optimised
to ensure lag-free turn-in characteristics. Like those of a lightweight-class racebike,
the frame headpipe and engine crankshaft move as a single unit when changing
direction, eliminating any sense of hesitation. Once in the turn, the Ninja ZX-6R holds
a line with precision and tracks through corners as if on rails.
Feedback is very detailed, with the bike communicating its every move directly to the
rider. The machine responds precisely and predictably to rider control inputs and
shifts in body weight, resulting in a chassis that makes the rider feel like a part of the
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 raises middleweight supersport performance to a new level.
Shorter throttle bodies deliver improved over-rev characteristics, while smaller
diameter bores offer more torque in the mid-range. Ultra-fine atomising
injectors improve combustion efficiency (and consequently fuel efficiency as
Pre-chamber Equipped Under-seat Muffler
A pre-chamber located below the engine feeds a compact and lightweight
under-seat silencer, a layout which improves mass centralisation. The
redesigned exhaust header pipes contribute to the improved exhaust
Tri-axis crankshaft and transmission shaft layout idealises the engine's CG,
reducing pitching movement during heavy braking and giving the rider
accurate chassis feedback. By reducing the amount of front/rear weight
transfer, the loads on the suspension and tyres are reduced, giving more
freedom when adjusting suspension settings.
New, fully adjustable inverted fork locates the main spring at the bottom of the
fork. Because the spring is completely submerged in oil, cavitation is
minimised, resulting in stable suspension performance even under the
demanding conditions of the circuit.
New rear suspension system features a pillow ball upper mount in place of the
earlier bushings for a more direct feel and improved feedback.
Compact projector beam headlights contribute to the aerodynamic front cowl
and a reduced frontal area. The new Ram Air duct is small but highly efficient.
The small under-seat silencer allows the tail section to be made narrower and
more aerodynamically efficient. This new design is the most aerodynamically
efficient of any Ninja available today.
Gear Position Sensor
In the heat of battle, even racers occasionally lose track of what gear they're in.
The convenient gear position sensor gives instant information to the rider -
especially useful should a mis-shift occur.
The system is also compatible with semi-auto shifters (permitted in AMA
Supersport racing) used to temporarily cut ignition to facilitate clutchless
Slim, waisted fuel tank makes it easier for the rider to grip the tank and seat
when hanging off in a turn.
