Kawasaki KX450F

The holeshot advantage: Launch Control Mode
The 2012 KX450F features a launch control system similar to that on our factory racers. With the simple press of a button, riders can activate a separate engine map designed to ensure efficient race starts in slippery conditions.Easy engine tuning: DFI Setting Data Selection (3 map choices)
Initial settings for the three maps are: Standard, Hard (conditions) and Soft (conditions). Using provided DFI couplers, riders are able to easily switch between the three maps to suit riding conditions. Plugging in each of the 4-pin couplers activates the corresponding engine map.
Each of the three maps can be reprogrammed using the optional KX FI Calibration Kit.High-performance piston
High-performance piston, featuring the same design used on our factory racers, contributes to improved performance at all rpm. A short skirt, reinforced external ribs and the industry’s only mass-production use of a bridged-box bottom, featuring fully flush internal bracing, result in a lighter, stronger piston.
Idealised piston rigidity balance care of a reconfigured bridge section contributes to increased mid-high rpm performance.
