The new Z900 epitomizes Kawasaki’s belief of what the ideal supernaked bike should be. Every twist of the throttle is rewarded with crisp, exhilarating acceleration, and an ultra-lightweight chassis lends itself to spirited sport riding. Designed for maximum riding pleasure, this sublime balance of power and handling make the z900 exceptionally exciting and easy to ride.
The Z900 motorcycle epitomizes Kawasaki’s belief of what the ideal supernaked bike should be. Every twist of the throttle is rewarded with crisp, exhilarating acceleration and an ultra-lightweight chassis lends itself to spirited sport riding. Designed for maximum riding pleasure, this sublime balance of power and handling make the Z900 exceptionally exciting and easy to ride.
With a smooth powerband that becomes more exciting as the revs rise, a light and nimble chassis, and distinctive Sugomi-inspired styling, the Z900 continues the Kawasaki legacy of creating legendary 900cc-class machines whose performance surpasses that of many full liter-class motorcycles.
The 948cc engine has a smooth, linear power delivery that is easy to control
and contributes to rider comfort and confidence, yet the strong mid-range hit
that pulls hard to redline provides plenty of exhilaration. Responsive
liquidcooled engine with efficient 4-valve, DOHC cylinder provides smooth
performance at all rpm.
• Lightweight crankshaft design augments the engine’s quick-revving character.
• A secondary engine balancer eliminates excess vibration, although a desirable
amount is left in to add to the bike’s character and acceleration feeling.
• Die-cast cylinder block is rigid while its open deck design helps save weight.
• Connecting passageways between the cylinders help reduce pumping loss,
improving high-rpm performance.
• The pistons are formed using the same unique casting process that is used for
making those found in the Ninja H2™/H2™R. The process creates hollow areas to
achieve idealized thickness for reduced weight without sacrificing strength.
• Downdraft intake design provides the fuel mixture with the straightest,
shortest path to the combustion chamber for increased performance.
• 29mm intake and 24mm exhaust valves complement the port designs and boost the
hard-hitting mid-range to highrpm power feeling.
Digital Fuel Injection(KP)
• 36mm throttle bodies are used for their ideal mid-range response.
• Sub-throttle valves, located behind the main throttle valves, are controlled
by the ECU so the EFI system has smooth, sensitive throttle response.
Enhanced Intake Note
• Acoustic tests helped shape the air box for a stimulating sound that varies
with engine speed to add to the riding experience, especially at high rpm.
• The air inlet faces upward so that the intake note is easier for the rider to
hear.
• A dividing wall in the center of the upper portion of the airbox accentuates
the high, clear intake note.
• Intake funnels balance performance and sound. The longer 150mm inner pair
strengthen the low-tomidrange performance while the shorter 50mm outer pair
enhance the intake sound.

Exhaust System
• 35mm exhaust headers are tuned for top-end performance while lowering exhaust
noise level at idle. Joint pipes between headers 1-4 and 2-3 help boost
mid-range torque.
• 5.5-liter pre-chamber allows a smaller muffler to be used and helps centralize
mass, as well as lowering the noise level at idle.
• Compact muffler design has dual internal chambers that helps to performance
and enhances the exhaust note. Stainless steel end cap and cover provide stylish
Z design elements. Assist and Slipper Clutch(KP)
• Using the rotational forces of the clutch hub and pressure plate, the clutch
is forced together during acceleration (Assist function) so that fewer and
lighter clutch springs can be
used for a lighter feel at the lever. During high back-torque, such as when too
low of a gear is selected during downshifting, the Slipper function allows some
clutch slippage to help prevent engine lock-up, stalling and rear wheel hop.
•Judder spring component helps prevent judder when the clutch is disengaged.
Transmission
• Short gear ratios for first through fifth gears provide strong acceleration in
the mid-range, the mostused part of the powerband for everyday riding.
• Sixth gear is an overdrive gear for more relaxed highway cruising.
Trellis Frame
• A key component to the Z900’s light weight, the frame weighs in at just under
30 pounds and contributes significantly to the bike’s light, nimble handling.
• Frame components follow the ideal pipe line so that the lines of the frame are
as straight as possible. When bends were necessary their angles were as small as
possible, resulting in a design that disperses stress extremely well.
• Five-point, rigidly-mounted engine is a stressed member, which contributes to
weight savings.
• Twin-tube rear frame section contributes to the low seat height and easy reach
to the ground while minimizing vibration transferred though the seat.
Inverted Front Fork
• 41mm inverted front fork features stepless rebound damping and spring preload adjustability in the left fork tube, with the adjusters conveniently located on the fork cap.
Horizontal Back-link Rear Suspension(KP)
•The linkage is placed atop the swingarm for better mass centralization and to
make room for the exhaust pre-chamber.
•Lay-down shock absorber is further away from the exhaust so that its operation
will not be affected by exhaust heat. The shock has adjustable preload and
rebound damping.
•Extruded aluminum swingarm is lightweight and rigid.
•Suspension settings provide both sporty performance and comfort.
Brakes
• Dual 300mm front petal discs and 250mm rear petal disc are clamped by dual
opposed piston calipers with resin brake pads to deliver ample braking power.
• A linear brake touch facilitates control for riders of all skill levels.
Anti-Lock Braking System (ABS)(KP)
• ABS model helps prevent wheel lock-up during sudden over-application of the
brakes or while braking on low-grip surfaces for an added degree of reassuring
braking performance.
Wheels & Tires
• Five-spoke star-pattern wheels are light weight with high rigidity to benefit
handling.
• Silica-blend Dunlop D214 Sportmax tires provide both enhanced wet-weather
performance and increased tire life.
CHASSIS
Control-centered Ergonomics
•A wide, flat handlebar and relaxed yet sporty riding position offers a blend of
control and comfort that allows the rider to enjoy a variety of riding
situations.
• The handlebar/seat/footpeg relationship helps enhance communication between
the rider and machine, giving the rider confidence-inspiring feedback.
• The fuel tank is narrow at the rear to help riders grip the bike with their
knees.
• A low seat height and slim overall design facilitates riders placing both feet
on the ground for smoother, confident stops.
• The rider’s seat is slim at the front to facilitate the reach to the ground
and wider towards the rear for good ride comfort.
• Rubber-mounted handlebar ends and footpeg pads, as well as rider footpeg
weights, help dampen vibrations for a more comfortable ride.
• Five-way adjustable brake and clutch levers accommodate a variety of hand
sizes for increased comfort.
ERGONOMICS
Distinctive Z Styling
•The Z900’s aggressive Z styling is inspired by the sugomi styling concept.
Sugomi describes the intense aura or energy given off by a person or object of
greatness and felt by the viewer. Someone, or something, possessing sugomi
inspires awe, leaves an indelible impression, is daunting in stature or ability,
and commands respect. Elegant bodywork flowing from head to tail is combined
with
minimalist coverage in the engine area is devised to draw attention to its
functional beauty. A condensed appearance emphasised by slim, close-fitting
bodywork gives the bike a light, agile image that reflects its sporty
performance.
• Headlight cowl and meter visor help form a slim, flowing line from the top of
the elegantly sculpted fuel tank for an aggressive appearance.
• Resin fuel tank cap has no visible bolts for a cleaner look.
•Engine shrouds have a sharp shape with minimal overhang add to the flowing
design, allow a clear view of the engine, and contribute to a condensed,
lightweight look.
•Under cowls have a unitized design so that they look like part of the engine.
•Flowing, upswept tail cowl contributes to the sporty image.
• LED taillight lights up in a Z shape.
