2007 Kawasaki Supersport Motorcycles Released

2007 Kawasaki Ninja ZX-6R

Features and Benefits

Key Features

High-Revving 599cc Four-Cylinder, DOHC Engine

New compact, narrow and lightweight design features a tri-axis crankshaft and transmission shaft layout to optimize the engine's center of gravity. This helps reduce pitch changes during heavy braking and gives the rider more-accurate feedback from the chassis
Narrow engine design allows excellent ground clearance

Four-Valve Cylinder Head

Compact valve train reduces cylinder head height
Intake ports and coolant passages were developed using flow analysis for efficient cylinder filling, more power, and maximum cooling efficiency
Forged sintered aluminum spring retainers are half the weight of steel retainers and allow higher rpm

Forged Pistons

Forged pistons are lighter, stronger and more heat resistant than cast versions.Ram Air Induction
Central ram air duct produces a straighter path to the airbox for maximum intake efficiency and provides the mounting surface for the instrument panel, eliminating brackets and weight
Flow analysis used to design efficient ducts to the airbox that also prevent water from reaching the air filter
Compact airbox and air cleaner are highly efficient and contribute to the compact riding position

Digital Fuel Injection

Shorter throttle bodies deliver improved over-rev characteristics
Smaller throttle bore diameter helps produce more torque in the mid-range
Ultra-fine atomizing injectors improve combustion efficiency, for better power output and lower fuel consumption

TCBI Ignition with Digital Advance

Pre-chamber Equipped Under-seat Muffler

New exhaust pre-chamber is located below the engine and contributes to better mass centralization
Revised under-seat silencer is significantly smaller and lighter to help mass centralization and allow for a more aerodynamic tailsection
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 performanceRacing-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
