Whether it s Team Green amateur racing, professional AMA Supercross or Motocross, the most successful 250cc motocross bike in the four-stroke category just got even better thanks to a series of upgrades designed to maximize the performance of this already impressive motorcycle. At a Glance Revised damping settings in the Showa Separate Function Fork (SFF) provides progressive damping force and features 48mm inner fork tubes for rigidity Revised Uni-Trak® rear shock settings New 270mm oversized front rotor, petal-style Braking-brand rotors front/rear New finer-atomizing Downstream Fuel Injector and revised ECU settings Launch Control increases ability to get good starts, by maximizing available traction New Bridged-Box-Bottom piston New Magneto Rotor with increased inertia Adjustable footpegs and handlebar clamps Lighter subframe New Factory styling High-revving, High-performance Engine 249cc, liquid-cooled, four-stroke, four-valve, single-cylinder DOHC 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 new Bridged Box piston with short skirts and reinforced external ribs for increased strength. 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 range Factory-Style Launch Control System The KX250F Launch Control was a first for the 250 class and increased the rider s 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, first or second gear Retards ignition timing in first and second gears, giving the greatest effect within the first few seconds of releasing the clutch Shifting into third 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 surfaces Digital Fuel Injection (DFI®) System New finer-atomizing Downstream Fuel Injector and revised ECU settings The dual injectors are fine-atomizing injectors with four holes. The upstream injector has a droplet size of 120µm, while the new downstream injector is 75µm. The finer size and wider spray pattern contributes to a stronger low- to mid-range power, improved response and quicker acceleration. Intake tract
