Electronics

• ADVANCED RIDER SUPPORT SYSTEMS: Next-level electronics offer the ability to harness the power and performance of the Ninja® ZX™-4R supersport in a way that delivers confidence over a wide range of riding situations and rider preferences.
• POWER MODES - POWER DELIVERY: A choice of Full Power or Low Power allows the rider to set power delivery to suit their riding preference or current conditions. 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.
• INTEGRATED RIDING MODES - CHOOSE YOUR MODE: All-inclusive modes that link Kawasaki TRaction Control (KTRC) and Power Modes allow the rider to easily set traction control and power delivery to suit a given riding situation. Sport – Enables riders to enjoy sporty riding. Road – Covers a wide range of situations, from city riding to highway cruising and rural roads. Rain – Offers reassurance when riding on a wet road surface. Rider (Manual) – Each system can be set independently.
• KQS - KAWASAKI QUICK SHIFTER: The Ninja® ZX™-4RR is equipped with a dual-direction quick shifter that enables clutchless upshifts and downshifts for seamless acceleration as well as quick and easy deceleration. This allows riders to take even greater advantage of the exhilarating engine character.
• KTRC - KAWASAKI TRACTION CONTROL: Kawasaki TRaction Control (KTRC) provides both enhanced sport riding performance and peace of mind when riding in low traction situations. Three rider-selectable modes offer varying levels of intrusion based on rider preference. Mode 1 – Least intrusive. Helps manage traction during cornering. 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 wheel spin is detected, engine output is reduced to allow grip to be regained.

Ergonomics

• LED LIGHTING - LIGHT THE WAY: Twin LED headlights, LED front turn signals, and an LED taillight help the Ninja® ZX™-4R and Ninja® ZX™-4RR supersport bikes stand out while also providing excellent illumination.

Supersport Power

• CLASS-LEADING POWER: Powered by a high-performance, in-line four-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.
• ENGINE - HIGH-REVVING: The strong 399cc liquid-cooled, 4-stroke, in-line four-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.
• RAM AIR - 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 contribute to stellar engine performance.
• EXHAUST - PERFORMANCE & SOUND: The exhaust system configuration contributes to strong power output and features a long silencer that produces a clear, racy exhaust note that can only come from an in-line four-cylinder Ninja® sportbike.
• TRANSMISSION - SMOOTH SHIFTING: The Ninja® ZX™-4R supersport features a smooth-shifting six-speed transmission, making it especially well-suited for accelerating out of corners when sport or track riding. The Ninja® ZX™-4RR adds a dual-direction Kawasaki Quick Shifter (KQS) which enables clutchless upshifts and downshifts for seamless acceleration and quick deceleration.
• ASSIST & SLIPPER CLUTCH - 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.
