649cc Parallel Twin-cylinder, DOHC EngineMost compact engine in its category, helps reduce the dimensions of the entire motorcycle
Triangular crank and transmission shaft layout makes it short from front to back
Semi-dry sump oil system reduces overall engine height
The narrow pitch of the chrome composite plated aluminum cylinders helps reduce engine width
Tuned to deliver smooth, responsive power in the low-to mid-rpm range for exceptional roll-on response ideal in negotiating city traffic
180-degree crankshaft plus balancer shaft smoothes engine pulses
Oil jets on the connecting rod big ends spray oil on the undersides of the pistons to aid cooling
Muffler with 3-way catalyzer and bullettip opening is mounted below the engine to help lower the center of gravity and aid weight centralization
Liquid CoolingKeeps engine temperatures consistent for long engine life and sustained power during hard use
Allows closer engine tolerances for more horsepower
Coolant is routed through the engine cases reducing the number of external hoses
Digital Fuel Injection (DFI)Utilizes 38mm Keihin throttle bodies with ECU controlled sub throttle valves for optimum performance and rideability
Sub throttles, located behind the main throttle valves, give the DFI system a more precise throttle response, similar to a constant velocity carburetor
Automatic fast idle system makes starting and warm-up easy
Precise fuel injection and exhaust catalyzer significantly reduce emissions
Digital Capacitor Discharge Ignition (CDI) SystemMicroprocessor controlled timing never requires adjustment and is ultra responsive to engine needs
Spark plug mounted stick ignition coils are compact and help reduce weight
Six-Speed TransmissionCassette style transmission with the shafts and shift drum in a compact layout that is easily removed as a single unit from the case for easier maintenance
High Tensile Steel Trellis FrameTrellis frame is small and light and Narrow at the knees and feet for increased rider comfort and control
Designed using 3-dimensional computer analysis to achieve the optimum stiffness balance for better handling
Single Shock Rear SuspensionAluminum gull-wing swingarm and offset, laydown single rear shock complement the frame design via an integrated line flowing from the steering head to the rear hub
Short, compact frame and engine design allows the swingarm to be longer, which helps improve overall handling
Showa shock has adjustable preload and rebound damping and uses a free piston and two-stage damping valves for smooth action during initial compression that becomes much firmer near the end of the stroke for a more planted feel
Long-Travel Fork41mm Inverted fork with stiff springs combines the best of dual sport and sportbike-type suspensions, to deliver excellent performance over a wide range of conditions
Tapered, relatively short outer tubes help provide the ideal stiffness balance to compliment chassis settings
Fork height, preload and rebound damping can all be adjusted to fine-tune the suspension to specific conditions or riding styles
Petal Style Brake DiscsBraking duties handled by dual 300mm front petal discs with two-piston calipers and a single 220mm rear petal disc with a single-piston caliper
Same rotor design as found on the Ninja supersport machines, petal design rotors offer improved cooling and warp resistance
Six-spoke wheelsAlso found on the Ninja ZX™-6R and ZX-10R; the six-spoke design requires much less material between spokes so that the rim thickness is thinner and overall wheel weight is reduced
Comfortable ErgonomicsEach part of the two-piece seat was designed with a different thickness and firmness of foam to optimize comfort for both rider and passenger
Passenger seat and grab bars were designed to provide a natural seating position for added comfort
Easy-to-read instrument panel has a large analog tachometer and digital readout for the speedometer, fuel gauge, odometer, dual trip meters and clock. White LED backlighting provides increased visibility at night
Adjustable WindscreenThree different settings, each 20mm apart, allows riders to set the windscreen height to suit their preferences
