Features

Engine

  • Race-team-inspired bridged-box bottom piston is lightweight and designed to match intake valves to optimize combustion efficiency for maximum performance at all rpms
  • The powerful and lightweight engine delivers instant throttle response, broad power delivery and incredible peak power
  • Exhaust header features an integrated resonator for crisp throttle response at low rpm and reduced exhaust sound level
  • High flow airbox with rear air intake channels for improved engine power
  • Rear seat intakes ensure clean airflow and contribute to improved throttle response

Frame and Styling

  • Lightweight aluminum perimeter frame for sharp handling. Redesigned triple clamp offers improved stability on corner entry to allow quicker turn-in. Slim frame spars and narrow shrouds allow easier rider movement. Optimized swingarm rigidity for maximum rear wheel traction.
  • Lightweight bodywork features Kawasaki’s first in-mold graphics for a durable, aggressive look. Lightweight bodywork with smooth, seamless surface at the rider's contact points. The KX graphics are now molded into the shrouds for greater longevity and an ultra-smooth outer surface.
  • Adjustable four-piston handlebar moves towards or away from your body. Two-position adjustable footpegs help reduce knee angle when seated.

Fuel Mapping

  • Handheld FI calibration controller eliminates need for laptop and 12V battery at the track. Allows the user to adjust fuel and ignition settings for ultimate performance. Can store up to 7 preset maps for different tracks.
  • Factory-tuned power settings with plug-and-play versatility. Select a coupler to access one of the 3 different preset engine maps. Standard, hard and soft terrain setting options.
  • Race-team-derived feature for grabbing the holeshot. Engages with a press of a button. Functions in first and second gears. Precise ignition timing helps ensure quicker acceleration with less slippage.

Suspension

  • Features low-friction fork seals and optimized valve settings for smooth action and progressive damping
  • Lightweight design with tuned rigidity to match chassis dynamics and optimize front end feel.
