2009 Kawasaki KX 450F Monster Energy, CALL 503-769-8888 EFI, a new chassis and ominous looks mean sleepless nights for the competition Sporting a new chassis, fuel-injected engine, bodywork and durability refinements, the 2009 Kawasaki KX 450F motocrosser represents high-tech racetrack domination. However, the all black KX450F Monster Energy® promises a cranked-up heart rate for anyone with a pulse, thanks to its black bodywork and wheels, green hubs and silver frame; highlighted by the aggressive Monster Energy graphics package. ADVERTISEMENT For racers looking to demoralize the competition, the sinister looking KX450F Monster Energy is the weapon of choice. Underneath its tough new appearance, the KX450F has undergone the biggest makeover since its original 2006 debut, but it still shares a clear bloodline with its championship-winning predecessors. The upgrade to Electronic Fuel Injection (EFI) eliminates the need to adjust engine settings to suit track and climate conditions and offers stable fuel-metering even in tough motocross conditions without sacrificing the hard-hitting character of its predecessor. The new EFI system includes a compact lightweight ECU, a 43mm throttle body, a newly designed lightweight aluminum in-tank fuel pump and an ultra-fine atomizing injector. Set at a 45° angle for ideal mid-range power, the 12-hole injector sprays precise 60 micron fuel particles for smooth power delivery and improved engine response at partial throttle. Designed specifically for motocross, the KX450F s lightweight EFI system doesn t require a battery the engine can be started within three rotations of the crankshaft, using only the electricity generated through the kickstarter. Kawasaki engineers achieved single-kick start capability by having the ECU power-up at the initial movement of the kickstarter. The system delivers electricity in the following order: ECU, fuel pump, and then injector.
