A lever device for operating a hydraulic actuator for a motorcycle comprises a support, a hydraulic actuator connected to the support, a main lever pivotally connected to the support for movement toward or away from the hydraulic actuator, and a timing lever pivotally connected to the support and connected to the main lever so as to operate the hydraulic actuator. An adjusting member is interposed between the main lever and the timing lever defines the relative position between the levers. An electric actuator changes the position of the adjusting member as a function of an electric power supplied to the actuator from a manually adjustable power supply.
