Achieved via an adjustment to the on-board ECU, only for EURO 4 models, at an authorised Kawasaki dealer, the adjustment is neither time consuming or irreversible so, when the time comes, it is possible to revert to orginal power output again via a short visit to the authorised dealer who will also create and update a record of the status. We also have A2 Compliant models that do not require a restriction kit.
