ZX-7R
The NINJA® ZX-7R
sportbike is the platform upon which Kawasaki`s championship-winning
Superbike was built. Featuring racetrack-derived technology, this
is the machine behind Doug Chandler`s back-to-back `96-`97 Superbike
titles, which extended Kawasaki`s AMA Superbike Championships to nine,
the most won by any single manufacturer. It also carried Chandler
and his teammate Eric Bostrom to a number of AMA Superbike victories
in 2001, 2000 and 1999. Finally, Kawasaki Drag Racing`s Rickey Gadson
is a three-time national champion aboard a Muzzy-prepared ZX-7R in
AMA/Prostar Drag Racing.
Keeping this Superbike champion competitive is a 748cc ultra-short-stroke
inline-four-cylinder engine. The short stroke and large bore help
increase reliability at high engine rpm and allow for more tuning
capability for racing applications. Direct-actuation valve-train components
relay the fuel mixture from four 38mm carburetors. Moderate exhaust-valve
timing produces strong midrange for real-world power on the street.
Exhaust gasses are then expelled through a 4-into-2-into-1 system
for optimum performance and quiet running.
A pair of large, aggressive air intakes at the front of the aerodynamic
fairing feed the ZX-7R`s Twin Ram Air Induction system. This system,
combined with a steep carburetor downdraft angle and Straight Shot
Intake ports, increases volumetric efficiency for more power.
The lightweight, aluminum, twin-spar perimeter frame was designed
using computer-aided technology. Sheets of aluminum alloy are pressed
to shape, and then welded together to produce remarkable strength
and low weight. An aluminum rear sub-frame also keeps the weight down,
yet provides the strength to carry a passenger.
The same engineering techniques were used to design the hollow cast-and-pressed
aluminum-hybrid swingarm. Lightweight aluminum components are also
used in the UNI-TRAK® rear suspension system, which produces progressively
stiffer damping and spring rates as the fully adjustable rear shock
is compressed. Front suspension is handled by a fully adjustable 43mm
inverted cartridge fork.
Strong braking is achieved through the use of 320mm semi-floating
front discs clamped by powerful opposed six-piston calipers at the
front. The rear brake features a 230mm disc with an opposed-piston
caliper.
Available in green and black or silver and black color schemes, the
NINJA ZX-7R`s good looks
accurately reflect its winning reputation.

• Steep down draft angle allows great breathing at high rpms
Digital Ignition
• Ignition-timing map closely matches ignition advance to the engine’s
needs, to produce power, fuel economy and long engine life
• Water-resistant connectors prevent corrosion
Twin Ram Air Induction
• Two air intakes in the fairing send cooler air to the carburetors for
more power
• As speed increases, pressurized air is supplied to the carburetors for
more horsepower
Six-Speed Transmission
• Both transmission shafts have involute splines for easy shifting with
less backlash
• Second through sixth gears have five undercut engagement dogs instead
of six, improving shift feel
• Positive neutral finder

• Designed for low noise level and good power production
Lightweight Aluminum Perimeter Frame
• Lightweight sheets of aluminum alloy are pressed to shape, then welded
together for a frame with amazing strength and low weight
• Wide frame spars give the frame torsional rigidity for incredibly precise
handling
Bottom-Link UNI-TRAK® Rear Suspension With Aluminum Hybrid Swingarm
• Reinforced cross pipe matches swingarm rigidity to the frame
• Design reduces unsprung weight for great rear suspension responsiveness
• Lightweight aluminum components assure quick suspension response
43mm Inverted, Cartridge-Type Front Fork
• Large-diameter, thin-wall inner tubes are rigid and light
• Adjustable compression and rebound damping to match a wide range of
operating conditions
• Special fork springs, bushings and pistons cut internal fork friction
to smooth the ride
Nitrogen-Charged Rear Shock
• Compression and rebound damping, preload and ride height are fully adjustable
• Piggyback reservoir keeps the shock fluid cooler for reduced fade in
harsh use
Six-Piston Caliper Front Brakes
• Six pistons in each caliper apply even pressure to the brake pads for
incredible stopping power
