In motocross racing, getting a good start is critical. A few tenths of a second can make the difference between getting the holeshot or getting buried in the pack. In slippery conditions, getting the maximum drive from a motocross bike requires precise control of both the clutch and throttle.
Launch Control Mode helps riders get out of the gate quickly by complementing high-level technique with engine management. Featured on a mass-production motocross bike for the first time on Kawasaki's KX™450F, the system activates a separate engine map designed to get a more efficient start off the line. The system is designed to the same specifications as that used by Kawasaki Factory racers competing in the AMA Supercross and Pro Motocross championships.
Launch Control Mode is activated simply by pressing a button on the handlebar. The Launch Control map slightly slows down the ignition timing to help tame the engine's strong torque and reduce wheel-spin off the start. Launch Control Mode is only active in the first two gears off the start, disengaging and returning to the standard engine map automatically once the rider shifts into third gear. The system gives riders a great advantage out of the gate and puts them in a better position to control the race.
Proper fit is key for rider comfort and control. However, the ideal fit varies from rider to rider, depending on their physical dimensions and riding style.
ERGO-FIT is an interface system designed to allow riders to find their ideal riding position. Various points of the chassis interface (the handlebar, footpegs and seat, etc) can be adjusted through a combination of interchangeable parts and parts with adjustable positions. This enables a wide range of riders to find a riding position that offers both comfort and control. Feeling at one with their machine, they will be able to experience how Kawasaki machines are fun and rewarding to ride.
*Adjustable parts and their range of adjustability vary by model.
