Features

Key Features
- Incredible power-to-weight ratio
- Race-oriented performance
- Track-tuned handling
- Aggressive aerodynamic styling

High-Revving 599cc Four-Cylinder, DOHC Engine
- Compact, narrow and lightweight design
- Tri-axis crankshaft and transmission shaft layout optimizes the engine’s center of gravity, reduces pitch changes during heavy braking and gives the rider more-accurate feedback from the chassis
- Light and strong forged pistons
- Narrow engine design gives excellent ground clearance

Four-Valve Cylinder Head
- Low cylinder head height with compact valve train
- Intake ports and coolant passages 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

Ram Air Induction
- Central ram air duct offers 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 minimal riding position

Digital Fuel Injection
- 38mm throttle bore helps produce more torque in the mid-range, while short throttle body length delivers good over-rev characteristics
- Ultra-fine atomizing injectors aid 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
- Exhaust header design contributes to improved exhaust efficiency
- Exhaust pre-chamber located below the engine contributes to better mass centralization
- Under-seat silencer is small and light to help mass centralization and allow for a more aerodynamic tailsection

Six-Speed Transmission
- Cassette-type transmission with a racing-style gear stack allows 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
- Optional springs, spring retainers and shims are available to fine-tune the clutch for specific track conditions

Gear Position Sensor
- Gear position sensor gives instant information to the rider, this is especially useful for improving consistency when testing settings on the racetrack
- System is 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
- Twin-spar perimeter-type frame is a mix of pressed and cast aluminum components welded together. This combination minimizes frame weight while still providing high strength and stability for responsive handling
- Chassis’s optimum center of gravity makes for easy roll response - particularly important negotiating a series of s-turns or returning to vertical after exiting a corner

Uni-Trak® Rear Suspension
- Uni-Trak® rear suspension system features pillow ball upper mount 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 under hard braking
- Small piggyback shock reservoir is designed to save weight

41mm Inverted Cartridge Front Fork
- Fully-adjustable 41mm inverted cartridge fork provides exceptional rigidity
- Equipped with top-out springs so the front wheel better follows the road surface when the front end is light during hard acceleration
- Bottom mounted main fork spring completely submerged in oil, minimizing cavitation and delivering 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. Individual pads provide increased cooling efficiency and can absorb more heat without deforming or losing brake feel at the lever than a large single pad, so they maintain consistent brake feel lap after lap
- Petal design brake discs offer excellent cooling and warp resistance

Aerodynamic Bodywork
- Design is the most aerodynamically efficient of any Ninja sportbike available
- Three-piece front fender with light and compact projector beam headlights and integrated front and rear turn signals add up to high aero efficiency
- Small but highly efficient ram air duct
- Exhaust system’s under-engine resonator allows the use of a smaller under-seat muffler, which allows a cleaner tail section further minimizing drag
- Different color panels create a sporty, aggressive image

Riding Position
- Ultra-compact chassis permits a ideal man-machine interface
- Slim fuel tank design makes it easier to grip the tank and seat when hanging off in a turn

Advanced Electronic Instrumentation
- Multifunction odometer, tripmeter, clock and lap timer/stopwatch
