The new ZX-6R was designed to take home trophies and set the quickest lap times, while being more exciting to ride than anything else in the middleweight sportbike category. The Ninja ZX-6R is a pure expression of Kawasaki’s racing philosophy.
We have not tested yet ths motorbike, but it is obviously a brilliant motorbike.
OK, it a little 600cc, ok it needs to take 192000 Rpm to fell power, but it is sexy and very efficient.
With 125 Bhp (131 Bhp with Ram Air) at 14500rpm for a maximum of 16500rpm.
Details review of this fantastic and promising machine:
Key Features :
- Incredible power-to-weight ratio
- Race-oriented performance
- Track-tuned handling
- Aggressive new aerodynamic styling
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:
- High-speed 32-bit ECU processor provides precise engine management
- Spark plug-mounted ignition coils are compact and help reduce weight
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 performance
Racing-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
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
Advanced Electronic Instrumentation:
- Multifunction odometer, tripmeter, clock and lap timer/stopwatch
