Quickly and easily load our Stock Class performance tune into your Kawasaki ECU eliminating the need to ship out your ECU for programming. Features a slick, full color, touch screen display. There is no limit to the number of vehicles or tunes you can reflash with the MaptunerX. Simply purchase one additional tuning license for each vehicle that you would like to program. Includes full access to RIVA's World Famous Tuning Library along with unmatched technical support. Easily switch between performance tunes and then back to stock settings if you wish.
