The 2011 Kawasaki KX450F sports innumerable upgrades from the previous models. This new motocross machine sports a new frame with a slightly narrower profile and sporting the same rigidity, a 4-way adjustable handlebar position, racing-like short silencer, adjustable foot pegs and even optional lower seat height.
Three standard engine mappings can be easily switched to by simply connecting the corresponding couplers, but the KX FI Calibration Kit lets the experienced rider fine-tune the bike to obtain the perfect response.
Even more, riders can activate the Launch Control mode with just a press of a button and enjoy the factory-specced engine mapping that provides the best starts: maximal power and thrust with minimal wheel slip.
