KTRC, Kawasaki's advanced traction control system provides both enhanced sport riding performance and the peace of mind to negotiate slippery surfaces with confidence. Multiple rider-selectable modes (the number of modes varies by model) offer progressively greater levels of intrusion to suit the riding situation and rider preference.
Less intrusive modes maintain optimum traction during cornering. Designed with sport riding in mind, they facilitate acceleration out of corners by maximizing forward drive from the rear wheel. And because Kawasaki’s sophisticated software bases its dynamic analysis on the chassis’ orientation relative to the track surface (rather than relative to a horizontal plane), it is able to take into account corner camber, gradient, etc., and adapt accordingly.
In the more intrusive modes (and for some models, in any mode), when excessive wheel spin is detected, engine output is reduced to allow grip to be regained, effectively enabling riders to negotiate both short, slippery patches (train tracks or manhole covers) and extended stretches of bad roads (wet pavement, cobblestone, gravel) with confidence.
Models equipped with IMU incorporate chassis-orientation feedback to offer even more precise management.
KTRC (Kawasaki Traction Control)
In motocross racing, getting a good start is critical. A few tenths of a second can make the difference between getting the holeshot or not. In slippery conditions, getting the maximum drive from a motocrosser requires precise control of the both the clutch and throttle.
Launch Control Mode helps riders get a good start by complementing high-level technique with engine management. Featured on a mass-production motocrosser for the first time on the Kawasaki 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 our factory racers competing in the AMA Supercross and Motocross championships.
Launch Control Mode is activated simply by pressing the button on the handlebar. The Launch Control map slightly retards 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 after the launch, disengaging and returning to the standard engine map automatically once the rider shifts into third gear. The system gives riders a great advantage when lining up at the gate and puts them in a better position to win.
Launch Control Mode
Models equipped with multiple Power Modes offer riders an easily selectable choice of engine power delivery to suit riding conditions or preference. In addition to Full Power mode, one (Low) or two (Middle, Low) alternate mode(s) in which maximum power is limited and throttle response is milder are provided.

Kawasaki’s RIDEOLOGY THE APP KX2 puts new functions, enhanced tuning capabilities and more information than ever before in the palm of your hand. This new app (not an update of the previous version) utilizes a connection with a built-in GPS unit to enable additional Trip Log capabilities for a next-level experience that can help sharpen lap times and fine-tune performance of compatible KX motorcycles.
RIDEOLOGY THE APP KX™2 offers an intuitive interface that enables riders to program the functions accessed through the handlebar buttons, such as Traction Control, Engine Maps and Launch Control. Engine tuning begins with riders selecting between 5 preset maps. For advanced tuning, each map can be further edited by the rider. Traction Control and Launch Control can also be preselected and tuned in the app, so riders can easily access these modes with the push of a button on the track.
Through the added input of a GPS unit located in the front fender, RIDEOLOGY THE APP KX™2 features Trip Log functions that allow riders to create track maps and analyze performance. The app also tracks running data allowing riders to review riding performance including gear position, engine RPM, and throttle position. A real-time monitoring function also allows these metrics to be viewed in the app, along with coolant temperature, intake temperature, battery voltage and preset modes.
An hour-meter function is linked to the ECU for handy maintenance reminders, and a new Information Guide is readily available for advice about engine map selection and suspension setup.
RIDEOLOGY THE APP KX™2 takes tuning and control to the next level. With an intuitive interface and the in-app Information Guide, it’s more possible than ever to fine-tune your KX motorcycle and sharpen your lap times.

Clever technology enables riders to connect to their motorcycle wirelessly. Using the smartphone application “RIDEOLOGY THE APP,” a number of instrument functions can be accessed, contributing to an enhanced motorcycling experience. Vehicle information (such as the odometer, fuel gauge, maintenance schedule, etc) can be viewed on the smartphone. Riding logs (varies by model, but may include GPS route, gear position, rpm, and other information) can be viewed on the smartphone. When connected, telephone (call, mail) notices are displayed on the instrument panel. Riders can also make changes to their motorcycle’s instrument display settings (preferred units, clock and date setting, etc) via the smartphone. And on certain models, it is even possible to check and adjust vehicle settings (such as Rider Mode, electronic rider support features, and payload settings) using the smartphone.
