2017 Kawasaki KX250F


Absolutely nobody can exceed the championship legacy of Kawasaki and the KX™ motorcycle. At any level. KX has more combined professional 250 and 450 class SX titles than anyone. At the amateur level, legends like Villopoto, Carmichael, Stewart, Emig, and McGrath all launched their incomprehensible professional careers with support from Team Green™, our amateur Motocross program. The common thread? The KX is The Bike That Builds Champions.

Advanced Technology

  • DFI® COUPLERS: Select a coupler to access 1 of the 3. Alter the engine characteristic with easy plug-and-play technology. Standard, hard and soft terrain setting options.
  • INDUSTRY-FIRST LAUNCH CONTROL MODE: Technology derived from Kawasaki factory race team. Activate with push of a button. Precise ignition timing helps optimize traction, minimizing slippage. Functions in first and second gears, automatically disengages in third gear.

Championship-Proven Power

  • ENGINE: Downdraft intake design and more upright engine orientation with revised cylinder offset increase overall power. Lighter weight race-team inspired bridged-box bottom piston to optimize combustion efficiency and plateau cylinder honing to help reduce friction. The lighter weight and increased power of the 2017 KX™250F motorcycle starts with a completely new engine. Get an inside look at the innovative design features.
  • INTAKES: Rear fender with under seat intake channels ensure clean airflow. Revised airbox and intake duct for increased air volume resulting in more power.
  • FUEL INJECTION: Innovative duel-injector system utilizes a downstream injector below the throttle valve, and a second upstream injector located near the airbox. Together, they contribute to more efficient filling of the cycle to maximize power. More upright engine orientation and repositioned intake duct allow for optimal air intake. The downdraft style routing improves cylinder-filling efficiency, contributing to increased engine power. New downdraft injector grows from four holes to eight for a wider fuel spray, delivering stronger low-to-mid-range power for quicker acceleration. Lighter weight 43mm throttle body ensures sharp, responsive power.

  • EXHAUST: New exhaust header with integrated resonator maximizes throttle response and enhances midrange power.

Class Leading Adjustability

  • SHOWA SEPARATE FUNCTION FORK - TYPE 2: The revolutionary Showa Separate Function Fork (SFF)-Type 2 is updated to match the razor-sharp performance of the new frame. The Showa SFF-Type 2 separates the spring and damping functions for lighter overall weight and greater efficiency. A revised inner-tube design fine-tunes fork rigidity while the super-hard titanium coating of the lower fork tube helps prevent scratches and reduces friction for ultra-smooth action. Together with revised valving, oil level and firmer spring rate, the new Showa SFF-Type 2 provides a more planted front-end feel. Preload adjustability and fully adjustable damping allow you to fine-tune your setup for superior handling and control.
  • 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.

New Frame & Bodywork

  • NEW SLIMMER, LIGHTER FRAME: New aluminum perimeter frame is narrower and lighter for championship-winning agility. Revised overall balance improves front wheel traction for razor-sharp cornering ability. Radiators are rotated inward for narrower width between shrouds, allowing easier rider movement.
  • AGGRESSIVE BODYWORK: New bodywork is lighter weight. Flatter tank and seat allow greater freedom of movement, Fuel tank has increased capacity, going from 1.6 to 1.7 gallons. Features Kawasaki’s first in-mold graphics that are more durable.
