Kawasaki Innovation Continues with Dual Injectors

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 usable power, increased durability, and the best-handling chassis yet.

Standard Features

Key Features
 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
 249 cc, liquid-cooled, 4-stroke, 4-valve, 1-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 43 mm 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  
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 31 mm intake and 25 mm 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 hydro-formed 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 2-tone shrouds offer a slim design  
 Side number plates also 2-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  
 50 mm 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 1-piece collar that provides additional stability during throttle operation  
 Lightweight short-length grips feature a pattern designed to provide excellent grip  
Factory-style Components
 Black alumite-coated rims, just like the factory racers  
 Titanium coated inner fork tubes to minimize stiction  
 Lightweight rims offer maximum strength and weight savings  
 Thick and rigid front fender  
 Rear brake pad material offers powerful braking performance  
 Front and rear petal brake discs help reduce unsprung weight, and the wave shape helps clean the brake pads for more efficient stopping performance  
 Rear caliper guard protects caliper from damage  
 Ribless rear hub and butted spokes further reduce unsprung weight  
 Renthal aluminum handlebar is standard equipment  
 Blue ignition cover plugs and oil filler cap match the blue accents on the factory race bikes  
 Factory-style graphics complement the KX250F’s highly tuned performance  
Additional Features
 New countershaft sprocket cover improves look  
 New polyurethane resin drive chain roller reduces weight  
 Redesigned air boot allows room for second fuel injector  
 Large resin skid plate offers great protection with minimum weight
