The 2010 Kawasaki KX450F is a motocross bike designed with flawless performance in mind. Not only it sports factory-inspired components, such as the top-drawer revised piston and race-oriented suspensions, but it also comes with new features to make riding better. The ECU now misses the traditional battery whose weight was stripped off the KX450F; the fuel injection system now needs no more adjusting on the fly depending on climate and track.
Expert riders can map their own ignition settings thanks to the optional KX FI Calibration Kit, able not only to tweak the engine characteristics, but also to record and analyze the gathered data. The fuel pump is not lighter and repositioning it ensured a more reliable operation.
This 449cc single-cylinder dirt beast will surely offer experienced riders all the brawn and high-class technology they need to prove their best.
