Awaken Your Supersport

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.

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.

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.

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.

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.

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.

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.

The 5-spoke star-pattern wheels and Dunlop GPR300 radial tires contribute to light, nimble handling, high grip, and excellent riding comfort.

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 manually adjusted independently

The Ninja® ZX™-4RR supersport 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.

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.

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.

The firm, comfortable seat facilitates rider weight shift during sport or track riding.

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. 

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.

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.

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.
