Kawasaki KX™450F

Kawasaki KX™450F 2012 highlights begin with the Supercross winning DNA of last year’s bike. The advanced design of the aluminum perimeter frame and dominating motor received a host of refinements to create a more compact and mass-centralized chassis propelled by more useable power than ever. Headlining the technological charge, the KX450F features an all new Launch Control Mode, which changes DFI settings with the push of a button to maximize traction out of the starting gate. This is accomplished without sacrificing any of the mid-range grunt or straight-line speed that made the KX450F famous.

No other production motocrosser offers a higher degree of adjustability to the rider interface or engine character than the new 2012 KX450F. With a choice of four different handlebar positions, two footpeg positions, and two optional plug-in DFI settings (plus virtually unlimited DFI mapping capabilities with the use of Accessory Kawasaki Racing Software Kit) – thanks to its advanced Digital Fuel Injection (DFI®) system – the KX450F is uniquely able to adapt to changing track and surface conditions and meet the needs of a surprisingly wide range of riders.
