2014 Kawasaki KX 250F, 2014 Kawasaki KX 250F 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® KX 250F. The 2014 KX 250F'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 KX 250F is still the dominant player in the 250cc ranks. Ride anything else, and you ll just be playing catch-up. Key Features may include: Launch Control is a first 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 overrev 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 four 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 comfort
2014 Kawasaki KX 250F, 2014 Kawasaki KX 450F It s no wonder that Kawasaki® s KX 450F has amassed an enviable championship record in AMA Supercross and AMA Motocross. Having a great rider definitely helps, and Monster Energy® Kawasaki® s Ryan Villopoto s credentials are impeccable, including double-up titles in AMA Supercross and Motocross titles in 2011, followed by another AMA Supercross title in 2012. And in 2013, Villopoto made it three straight Supercross championships in a row, becoming the first rider to win back-to-back-to-back AMA Supercross titles since the great Ricky Carmichael, another rider whose career blossomed aboard Team Green machines. Key Features may include: Launch Control helps to reduce wheelspin on slippery starting gates Kayaba Pneumatic Spring Fork (PSF) uses compressed air to reduce weight, compared to traditional metal-coil fork springs, providing effective tuning and bottoming resistance Includes a free Kawasaki Genuine PSF Air Fork Pump and removable adjustment valve for quick and easy tuning of fork spring pressure Engine is tuned for optimum power delivery all the way from basement revs through the upper rpm range, this results in impressive thrust that continues from corner-exit to the end of the straights Piston crown shape allows for superior ultra-low to mid-range engine response Intake cam features slightly less lift, to promote better low-rpm throttle response Front master cylinder features a knocker-style lever-to-piston interface for improved brake feel and more consistent performance than the old piston-type unit Wide, low-density grips make life easy on the rider s hands Lightweight 240mm petal-type rear rotor features the same aggressive petal style as the front rotor and is gripped by a single piston hydraulic rear caliper Launch Control helps to reduce wheelspin on slippery starting gates Pre-programmed ignition maps are interchangeable trackside, no PC required Adjustable 4-position handlebar and 2-position footpegs allow riders to fit the KX to match their personal preference Black anodized aluminum rims for a factory look Narrower grips are softer and more comfortable for 2014
