Full Power – Allows the rider to enjoy the unadulterated performance of the engine. Low Power – Prioritizes manageability by offering power delivery and throttle response that's optimized for less-than-perfect weather and/or road conditions.

Designed with sport riding in mind to facilitate acceleration out of corners. Mode 2 – Intervention occurs earlier. Offers a balance of sport riding support and enhanced rider confidence. Mode 3 – Most intrusive. When excessive wheelspin is detected, engine output is reduced to allow grip to be regained.

Supersport Power

• CLASS-LEADING POWER: Powered by a high-performance, in-line 4-cylinder 399cc engine with advanced racing-inspired technology, the Ninja® ZX™-4R supersport is a force to be reckoned with both on and off the track.
• HIGH-REVVING: The strong 399cc liquid-cooled 4-stroke in-line 4-cylinder engine delivers exhilarating performance and class-leading power to eclipse the rest of the 400cc field. Developed with feedback from other Kawasaki Ninja® ZX™ supersport machines, the engine's quick-revving nature and direct throttle response offer strong low- to mid-range torque for city riding and screaming high-rpm power ideal for sport or track riding.
• EFFICIENT PERFORMANCE: A trademark feature of Ninja® ZX™ models, the ram air intake system features a central intake and side duct that work with a downdraft intake to improve cylinder-filling efficiency to deliver stellar engine performance.
• PERFORMANCE & SOUND: The exhaust system configuration produces strong power output and features a long silencer for a clear, distinctive exhaust note that can only come from an in-line 4-cylinder Ninja® sportbike.
• SMOOTH SHIFTING: The Ninja® ZX™-4R supersport features a smooth-shifting 6-speed transmission, making it especially well-suited for accelerating out of corners when sport or track riding. The Ninja® ZX™-4RR supersport adds a dual-direction Kawasaki Quick Shifter (KQS) which enables clutchless upshifts and downshifts for seamless acceleration and quick deceleration.
• KEEP THE MOMENTUM: A racing-developed Assist & Slipper Clutch provides light clutch-lever pull and reduces back-torque when excessive engine braking occurs due to quick or unintended downshifts. This helps prevent rear tire hopping and skidding.
