Features

Engine

  • ENGINE: Race-team-inspired Bridged-Box 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: Exhaust header features an integrated resonator for crisp throttle response at low rpm and reduced exhaust sound level.
  • INTAKES: Rear seat intakes ensure clean airflow and contribute to improved throttle response. High flow airbox with rear air intake channels for improved engine power. High flow airbox with rear intake channels for improved engine power.

Frame and Styling

  • SLIM, LIGHTWEIGHT CHASSIS: 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 rigidty for maximum rear wheel traction.

Frame And Styling

  • AGGRESSIVE BODYWORK: 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 an an ultra-smooth outer surface.
  • ERGO-FIT™ ADJUSTABILITY: The adjustable handlebar mounts provide a choice of 4-positions (35mm range of adjustment) enabling the rider to set-up their ideal riding position. Factory-style Renthal handlebar and handlebar pad come standard.
  • ERGO-FIT™ FOOTPEGS: Two-position adjustable footpegs help reduce knee angle when seated. Footpegs allow the rider to adjust center of gravity by 5mm.

Fuel Mapping

  • ADVANCED FUEL MAPPING TECHNOLOGY: The KX™ 450F motorcycle features several advanced ignition and fuel-mapping systems for precise adjustability.
  • FI CALIBRATION KIT: 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.*Sold Seperately as a Kawasaki Accessory.
  • DFI® COUPLERS: 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.
  • LAUNCH CONTROL MODE: 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

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