- Designed for #1 performance on the circuit and winding roads
- Power boosting features include bigger intake and exhaust valves, new cams, and larger
- area oval-shaped sub-throttles fed by dual injectors
- Exhaust valve integral with the under-seat muffler improves low- and mid-range engine performance
- Improved aerodynamics give this middle-weight SuperSport the best CdA of any NINJA to date
- Back torque limiter is standard
- New frame and swingarm with revised chassis dimensions improve cornering performance
- 300mm petal-style front disc brakes with radial-mount calipers and direct-action brake master cylinder provide excellent performance and feel
- Revised riding position based on the ZX-10R lets the rider take advantage of the awesome performance
Engine Details
- New cylinder head design locates each pair of intake/exhaust valves farther apart for improved breathing and higher combustion efficiency
- Complementing the new head are new pistons with reshaped crowns and improved, low-friction skirt profiles
- Larger diameter intake and exhaust valves, together with new cam profiles, contribute to the new engine’s enhanced performance
- Dual-injector fuel injection system uses fine atomizing injectors for the main injectors and features a set of secondary injectors located in the airbox for improved cylinder filling, crisper throttle response and higher power output
- Extremely narrow included valve angle of 25 degree allows the fitting of large valves in a compact, highly efficient combustion chamber
- Breathing passageways, one located between each pair of cylinders, contributes to effective crankcase breathing, which reduces pumping loss
- Thicker castings used for the engine cases improve engine rigidity and reduce vibration and feature improved lubrication
- The new lower case has separate mounting bosses for the oil filter and oil cooler
- New aluminum oil cooler improves cooling efficiency.
- Further performance gains were achieved by increasing the width of the oil pump while changing its drive ratio to reduce its rpm
- Deeper oil sump lowers the oil level for reduced windage losses
- The crankshaft has been strengthened to reduce flexing and now features larger diameter main journals (from 30mm to 31mm), and the crank has been re-balanced for smoother running
- Catalytic converter located at the collector helps keep emissions friendly
- New auto-fast-idle system improves starting
