Kawasaki Z 900

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.

Features

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.
