Just in from the MX Track… The newest releases from the Kawi factory are the KX 450F and the KX250F. "Winning championships is what this bike's built to do. To keep the momentum strong, we packed the KX250F with even more championship proven technology." Pricing and availability will be announced in Mid-July. 2014 Kawasaki KX250F
New for the 250 will be a Launch Control Mode that was introduced 2 years ago on the 450F, but this year it is making its way down to the 250F. The Launch Control mode is a rider set function on the handlebars that, once activated, will illuminate a red light. This lets the rider know at the start gate that the system is activated and poised to give him the optimum engine mapping to give him the best possible acceleration, all while improving traction on both hard and soft surfaces by limiting and controlling wheel spin. Once the rider reaches third gear, the Launch Control self terminates and takes the ECU out of the way to allow the rider's right hand to control the wheel spin.
They retained the 249cc motor that is race and championship proven.
They made improvements to the transmission that will provide smoother shifts that will be noticeable while riding. This means smooth power delivery throughout the gears.
The frame and suspension was given a bit of beef as well. The engineering team went through and improved on the already championship level frame by introducing new motor mounts that provide a bit more frame rigidity, and thus more traction in the front wheel. This is something that was not available in the aftermarket, so the factory took it upon themselves to make the bike better in house. This is a testament to their commitment to keeping their riders on winning bikes.
Lastly, they revised the Showa Fork system to create better balance, smoother action as well as reducing the chances for bottom out. 2014 Kawasaki KX450F
The features that have been released and revolutionary in the last few years have been retained in the 2014 bike. They revolutionized the industry with their Launch Control system two years ago, and they did it again by introducing the PSF forks. Both of these systems are retained in the 2014.
The same Launch control system is the same as the 250F, but the Pneumatic Spring Fork is exclusive to the 450F. This system has been making the rounds in recent years to change the game for a lot of manufacturers. All of the Top 10 Riders have pneumatics in their fork tubes instead of medal springs. This system is lighter and more adjustable than traditional springs. You essentially change your "spring rate" with nothing more than a small air pump that is supplied with the bike. The pneumatic system is more responsive and are more progressive than medal springs. The more you compress it, the stiffer they get.
The Power Mode Couplers is another trick bit of kit for the 450F. These are 3 plug and play connectors that will change the engine mapping according to track conditions and/or personal preferances. You are provided the choice of Green, which is a more balanced engine map; Black, that provides smoother power delivery for harder surfaces; and White, which will provide sharper throttle response.
They also improved upon the ergonomic adjustability with the addition of a 4 way handlebar adjustment, as well as adjustable foot pegs for added comfort on long practice days, or a multi-heat race day.
