* Price shown is based on the manufacturer's suggested retail price (MSRP) and is subject to change. MSRP excludes destination fees, optional accessories, applicable taxes, installation, setup and/or other dealer fees.Take a look at the record books and you'll see that no other 250cc motocross bike in the modern four-stroke era has earned more championship titles in AMA Supercross and Motocross than the Kawasaki KX250F. The 2014 KX250F's championship-winning technology includes a new Launch Control system, a plug-and-play adjustable ECU, Separate Function Fork (SFF), new motor mounts, revised suspension tuning and an upgraded transmission. Make no mistake, the KX250F is still the dominant player in the 250cc ranks. Ride anything else, and you'll just be playing catch-up. At a Glance... Launch Control is a 1st for the 250 class and increases ability to get good starts, by maximizing available traction Showa Separate Function Fork (SFF) provides progressive damping force and features 48mm inner fork tubes for rigidity Dual injector Digital Fuel Injection (DFI) system High-rpm engine output extends deep into the over-rev High-tensile steel front engine mount plates are 29% thinner than last year's steel plates and offer a better mix of chassis rigidity, improved feedback and superior front-end grip Transmission gears feature 4 dogs instead of three, for enhanced shift smoothness Shift-fork grooves are more-direct to enhance feel at the shift lever Counter-shaft and sprocket retainer design now uses a nut and washer instead of a clip, for a more positive sprocket to countershaft interface and simplified sprocket swaps Upgraded crankcase oil jet delivers an optimized stream of oil to the underside of the piston, for enhanced cooling Revised throttle body tuning improves airflow from a closed-throttle, for a smoother idle and enhanced low-end response Revised piston tuning in the left fork leg enhances damping performance through the initial and mid-stroke Revised rear shock settings provide a more comfortable baseline for a wide range of riders Grips feature shorter barrels and are made from a softer material to enhance rider comfortHigh-Revving, High Performance Engine 249cc, liquid-cooled, four-stroke, four-valve, single-cylinder DUAL OVERHEAD CAM engine delivers hard-hitting power across the rpm range Nickel plating on the cylinder wall has a high adhesion factor for optimum durability Thick-stem connecting rod resists flex and enhances durability Upgraded crankcase oil jet delivers an optimized stream of oil to the underside of the piston, for enhanced cooling Thick crank web design features a balance factor on par with the factory racers to help minimize engine vibration, provide smooth power delivery and maximize performance in the mid-high rpm rangeFactory-Style Launch Control System Launch Control is a 1st for the 250 class and increases ability to get good starts, by maximizing available traction Launch Control is activated by pushing a button on the left handlebar while stopped, in neutral, 1st or 2nd gear Retards ignition timing in 1st and 2nd gears, giving the greatest effect within the 1st few seconds of releasing the clutch Shifting into 3rd gear automatically deactivates Launch Control Mode and returns the ignition to normal mapping Particularly effective when chasing the holeshot from concrete starting pads and other slippery surfacesDigital Fuel Injection (DFI) System Intake tract designed to provide optimal airflow from the airbox into the combustion chamber Seal between air inlet port and throttle position sensor unit on the 43mm throttle body protects TPS sensor from fuel penetration Progressive throttle linkage for sharp and precise throttle response across entire rpm range Simple and efficient system: No battery, fuses or relays Offers easy engine starting Helps prevent engine hesitation after landing from jumps and other high-impact situationsBridged Box-Bottom Piston Piston profile helps increase reliability compared to non-box-bottom design Light and strong piston shares same design as the factory racers, and a tin plating to optimize its interface with the nickel plating on the cylinder wall Special finish improves surface lubrication and wear resistance Short piston pin reduces reciprocating weightLightweight and Efficient Top End Intake valve seat material offers increased durability Ultra-light valves have extremely thin valve stems on par with those found in supersport machines; intake valves feature thick heads for increased strength Special casting method leaves the intake port surfaces extremely smooth for optimum intake efficiency across the rev range Silicon-coated head gasket provides excellent sealingStainless Steel Exhaust System Head pipe resonator chamber helps boost low-rpm torque High-volume muffler assembly features a large cross section to keep noise levels at 94 dB while retaining power production Durable stainless steel constructionEfficient Cooling System Thick 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 coolingTransmission and Shifting Transmission gears feature 4 dogs instead of three, for enhanced shift smoothness Shift-fork grooves are more-direct to enhance feel at the shift lever 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 maintenanceQuick-turning Chassis The KX250F's slim and lightweight aluminum perimeter frame helps provide excellent ergonomics and handling 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 squatSeparate Function Fork 48mm Separate Function Fork (SFF) delivers firm damping response and increased ride comfort SFF design separates springing and damping functions for less weight, better performance, less stiction and easier adjustability compared to traditional forks Revised piston tuning in the left fork leg enhances damping performance through the initial and mid-stroke 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 excellent protection for the inner tubesUni-Trak rear suspension Rear shock features dual compression adjustability, allowing high-speed and low-speed damping to be tuned separately Features Kashima Coat on the inside cylinder wall for reduced friction and smoother suspension action Revised rear shock settings provide a more comfortable baseline for a wide range of riders Swingarm features 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 ratios for the Uni-Trak rear suspen
