Features

Advanced Technology

  • HIGH-TECH SUPERSPORT: Race DNA and advanced technology is what the Ninja® family is known for. So it comes as no surprise that the Ninja® ZX™-6R supersport bike features the advanced technology and performance you expect from a Ninja.
  • INTEGRATED RIDING MODES: The Ninja® ZX™-6R supersport motorcycle features 4 integrated riding modes (Sport, Road, Rain, or Manual) that allow the rider to select the level of traction control and power to suit the current riding conditions.
  • TFT COLOR INSTRUMENTATION: The 4.3-in all-digital TFT color instrumentation with smartphone connectivity gives the rider important information at a glance, as well as the convenience and safety of a hands-free smartphone connection.
  • KAWASAKI TRACTION CONTROL (KTRC): The Ninja® ZX™-6R supersport bike features Kawasaki TRaction Control (KTRC), which provides 3 levels of assistance to cover a wide range of riding conditions, ranging from enhanced sport riding to helping manage low-traction surfaces.
  • POWER MODE SELECTION: The Ninja® ZX™-6R supersport bike allows riders to choose from Full Power or Low Power mode to suit the riding situation.

Handling

  • PRECISION PERFECTED: The Ninja® ZX™-6R motorcycle gets ahead of sharp turns with optimized engine performance across the entire rpm range, class-leading components, and advanced rider support technology.
  • SUPERIOR BRAKING PERFORMANCE: Highly rigid, radial-mount monobloc calipers deliver a firm feel at the lever for superb control. Large, 310mm round disc brakes and a radial-pump front brake master cylinder complete the front brake package, ensuring powerful braking with excellent feel. A 220mm round disc brake and lightweight caliper slow the rear wheel.
  • GRIP & CONQUER: With Pirelli Diablo™ Rosso IV tires, experience unmatched confidence, lighter handling and, ultimately, more thrills when you take command of sharp turns, thanks to superior grip in a variety of conditions.
  • CONFORM TO THE ROAD: Fully adjustable Uni-Trak® rear suspension with progressive damping helps maintain rear wheel traction while putting power to the ground. This leads to confident braking and predictable handling both on and off the track.

Power

  • FLEX ON THE STREET & TRACK: Powered by a potent 636cc engine and advanced performance technology, the Ninja® ZX™-6R supersport motorcycle delivers legendary Ninja® power on and off the track.
  • THE 636 ADVANTAGE: The advantage offered by the Ninja® ZX™-6R supersport motorcycle's 37cc greater engine displacement is significant for real-world riding exhilaration. Greater performance across the rpm range is welcome when sport riding, both on canyon roads and on the racetrack. But stronger low- and mid-range torque compared to “ordinary” mid-size supersport models also offers increased usability in everyday street riding situations.
  • KEEP THE MOMENTUM: A high-quality Assist & Slipper clutch reduces back-torque when excessive engine braking occurs to help maintain a high speed through turns in order to enter the next straight-away with optimal momentum.
  • KAWASAKI QUICK SHIFTER: This highly reliable contactless-type quick shifter enables ultra-quick upshifts at full power for seamless, maximum acceleration on or off the track. When the shift lever has been activated, the system sends a signal to the ECU to momentarily cut ignition so that the next gear can be engaged for clutchless shifting.

Styling

  • BEAUTIFULLY AGGRESSIVE: The Ninja® ZX™-6R supersport motorcycle features smooth-flowing supersport styling with 3D interwoven bodywork.
  • DISRUPTIVE DESIGN: Distinct front and side cowls, sporty windscreen, and all-LED lighting create the recognizable Ninja® look.
  • LIGHT UP THE RIDE: Hybrid projector/reflector headlights, featuring mono-focused LED technology, are supplemented by LED turn signals and deep-set reflectors.
  • CLEAN DESIGN: The blacked out engine covers and muffler body add to the sporty look of the Ninja® ZX™-6R supersport bike.
