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 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.
• 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.
• 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 wheelspin is detected, engine output is reduced to allow grip to be regained.

Ergonomics

• CONTROL & COMFORT: A naturally aggressive yet slightly relaxed riding position lets riders take greater advantage of the Ninja® ZX™-4R supersport bike's nimble handling while also providing a balance of wind protection and aerodynamics.
• SLIM DESIGN: The slim fuel tank allows for excellent rider contact with the bike. The low top of the fuel tank allows the rider to get into a tucked position.
• ADJUSTABILITY & FEEL: The adjustable brake and clutch levers (5 available positions for each) allow the rider to tailor the lever position to suit their hand size and preference. Supersport-style aluminum footpegs offer a direct feel and good control when sport riding.

Handling

• LEGENDARY HANDLING: The Ninja® ZX™-4R supersport offers the best of both worlds with light maneuverability when riding in the city, and high-level supersport handling when sport or track riding. Key chassis dimensions were inspired by the Kawasaki Racing Team’s WorldSBK Ninja® ZX™-10RR race bike.
• SUPERSPORT-STYLE HANDLING: Designed using advanced dynamic rigidity analysis, this trellis frame delivers the required balance of strength and chassis flex to achieve nimble supersport-style handling.
• BEST OF BOTH WORLDS: The 37mm inverted fork with SFF-BP internals of the Ninja® ZX™-4R supersport offers both racetrack performance and everyday usability. The Ninja® ZX™-4RR supersport front fork adds adjustable spring preload to further tailor performance to suit rider's preference.
• CONFIDENCE-INSPIRING: The horizontal back-link rear suspension offers a firm, planted feel that is reassuring during sport riding while also providing ample bump absorption for ride comfort when riding around town. The Ninja® ZX™-4RR supersport is equipped with a highly adjustable Showa BFRC lite shock.
• HIGH-PERFORMANCE BRAKING: Dual front discs are gripped by radial-mount monobloc calipers, complemented by a large-diameter rear disc that offers strong stopping power and superb feel. The Ninja® ZX™-4R supersport features Nissin's most compact and lightweight ABS control unit.

Styling

• SHARP & AGGRESSIVE: The aggressive full-fairing design emits a fierce aura of restrained power and explosive action, while the sharp chin spoiler contributes to the strong Ninja® family image.
• TRADEMARK STYLING: A trademark feature of Kawasaki’s Ninja® ZX™ models, the ram air intake, prominently located at the center of the upper cowl, instantly sets the Ninja® ZX™-4R supersport apart from the competition. The ram air duct that passes to the left of the front fork is visible to the rider and is stamped with “Ram Air” as a reminder of this machine’s high performance.
• CLEAR VIEW: The 4.3-in. all-digital TFT color instrumentation gives the cockpit a high-tech, high-grade look. It features a Circuit Mode for lap timing and displays track-related information in a more prominent, easier-to-view layout.
• CONNECTIVITY: Smartphone connectivity via RIDEOLOGY THE APP* connects you with your bike like never before, allowing you to view vehicle info, a riding log, phone notifications, and general settings. *RIDEOLOGY THE APP is not intended for use during vehicle operation. Only use RIDEOLOGY THE APP when the vehicle is not being operated and it is safe to do so.
• 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 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.
