No other bike in its class has spent more time on the AMA Supercross podium than the Kawasaki KX™250F. The race-proven technology of the quarter-liter motocross leader returns for 2012, but with added enhancements that give the KX250F even more useable power, increased durability, and the best-handling chassis yet.

At A Glance...
  • New dual injector Digital Fuel Injection system
  • More robust high-rpm engine output extends deep into the overrev
  • Revised transmission offers improved shifting action and durability
  • Thicker, stronger engine components improve reliability
  • Revised Showa Separate Function Fork (SFF) offers more supple initial hit, and improved action during corner entry
  • Increased spring rates on front and rear suspension enhance traction and offer a more solid feel
High-Revving, High Performance Engine
  • 249cc, liquid-cooled, four-stroke, four-valve, single-cylinder DOHC engine delivers hard-hitting power across the rpm range
  • Improved decompressor spring action for easier starting
  • New nickel plating on cylinder walls has a higher adhesion factor for increased durability
  • New connecting rod has a thicker stem for improved reliability
  • New more rigid crankshaft is re-balanced for better performance and higher durability
  • Thicker crank web design features a balance factor on par with the factory racers for reduced engine vibration, smoother power delivery and increased performance in the mid-high rpm range
  • Revised ACG stator and rotor inertia complements the changes made to the crankshaft
Digital Fuel Injection (DFI) System
  • Upgraded system adds a new “upstream” injector located closer to the airbox
  • All-new second injector features different body size, but same capacity as primary injector
  • Added seal between air inlet port and throttle position sensor unit on the 43mm throttle body protects TPS sensor from fuel penetration
  • Progressive throttle linkage opens more quickly after 3/8 open position
  • Simple and efficient system: No battery, fuses or relays
  • Sharp and precise engine response across entire rpm range
  • Offers easy engine starting
  • Helps prevent engine hesitation after landing from jumps and other high-impact situations
  • Optional accessory calibration Kit features new 6-pin connector type allows easy tunability
  • Optional accessory FI Indicator Light allows the DFI system to communicate diagnostic information
Bridged-Box Bottom Piston
  • Light and strong piston shares same design as the factory racers, with a new tin plating to optimize its interface with the new nickel plating on the cylinder wall
  • Changed shape of streak finish improves lubrication and wear resistance
  • Short piston pin reduces reciprocating weight
Lightweight and Efficient Top End
  • Lightweight, highly rigid, titanium 31mm intake and 25mm exhaust valves reduce reciprocating weight and offer high-rpm reliability
  • Ultra-light valves have extremely thin valve stems on par with those found in supersport machines; intake valves feature thick heads for increased strength
  • Intake ports designed for peak performance at all rpm, especially in the high-rpm range
  • Special casting method leaves the intake port surfaces extremely smooth for optimum intake efficiency across the rev range
  • Silicon-coated head gasket provides excellent sealing
Stainless Steel Exhaust System
  • Stainless steel construction offers extra durability
  • High-volume muffler assembly keeps noise levels at 94 dB while retaining power production
  • Joint between pipe and muffler offers excellent sealing, while a rubber damper collar on the rear silencer mount equals serious durability
Efficient Cooling System
  • Thick and wide radiators are strong and offer excellent resistance to mud buildup while providing superb cooling performance
  • Cylinder head water jacket routes coolant to the front of the cylinder head for even cooling
Transmission and Shifting
  • Shorter shift fork stroke and more smooth solid shift forks (not hollow) offer improved shifting action
  • Strong, beefy crankcases feature additional material around the engine mounts to help increase long-term durability
  • Clutch cable holder is integrated with the crankcase for accurate feel at the clutch lever
  • Scavenge oil filter screen can be accessed without splitting the crankcases, facilitating easier maintenance
Quick-Turning Chassis
  • Utilizes a low-rigidity steering stem for lighter handling
  • The KX250F's slim and lightweight aluminum perimeter frame is composed of forged, extruded and cast parts
  • Center of gravity and key dimensions such as swingarm pivot, output sprocket and rear axle locations designed to increase forward drive with minimal rear-end squat
  • Upper engine mounts on head cover sides increase overall rigidity
Race-Oriented Suspension
  • Revised race-oriented suspension features heavier spring rates and revised damping settings both front and rear
  • Separate Function Fork (SFF) separates springing and damping functions for less weight, better performance, less stiction and easier adjustability
  • Fork features the only external spring preload adjustability in its class
  • Super-hard titanium coating on the outer surface of the inner fork tubes reduces stiction and improves suspension action while also helping prevent scratches and tube damage
  • Friction-reducing Kashima Coat treatment on the inside of the outer fork tubes contributes to smoother suspension action
  • Wrap-around fork tube guards provide greater protection for the inner tubes
  • Altered piston rod specs improve shock setting flexibility and offer better rear wheel traction
  • Features Kashima Coat on the inside of the shock reservoir for reduced friction and smoother suspension action
  • Rear shock features dual compression adjustability, allowing high-speed and low-speed damping to be tuned separately
Superior Rear-Wheel Traction
  • Swingarm features optimum internal bracing and flex characteristics for superb cornering performance
  • Alloy swingarm uses a cast front section, tapered hydroformed spars and forged chain adjusters
  • Uni-Trak® rear suspension linkage system mounts the suspension arm below the swingarm, allowing more rear suspension stroke and precise tuning
  • Linkage system receives upgraded tie-rod which has less rigidity for smoother suspension action and improved traction
  • Linkage ratios for the Uni-Trak rear suspension match rear shock damping settings to achieve maximum rear wheel traction
Rider Interface
  • Bodywork components offer the rider a slim interface, making it easy for racers to feel comfortable and go fast
  • Formed using a double-injection molding process, the two-tone shrouds offer a slim design
  • Side number plates also two-toned and contribute to the slim package
  • Right side panel has an added passageway to help cool the silencer
  • Frame is wider at the ankles to offer better grip and narrows near the bend below the seat to allow a slim riding position
  • Slim seat features upgraded polyurethane, designed for greater durability
  • Seat has a slip-resistant top and side surface for good grip when seated and while standing
  • 50mm wide (front-to-rear) footpegs offer superb grip and feel at the pegs
  • Clutch cable boot features a large quick adjuster, making it easy for riders to adjust play in the clutch cable while on the fly
  • Throttle grip has a one-piece collar that provides additional stability during throttle operation
  • Lightweight short-length grips feature a pattern designed to provide excellent grip
Factory-Style Components
