Abstract
A rally-oriented meter device for motorcycles, includes a meter unit, a fixing assembly for fixing the meter unit in the vicinity of a handle bar of the motorcycle, and a sensor for detecting the number of revolutions of a front wheel of the motorcycle. The meter unit has an internal electric circuit, a display section, and an operational section. The internal electric circuit comprises an integration circuitry for an integration of a travel distance of the motor cycle. A correction circuitry provides the integration circuitry with a correction signal representing a correlation factor. The operational section comprises a calibration switch system for providing a control signal for commanding the correction circuitry to start and stop an action thereof to determine the correction factor. The display section comprises a first display element for displaying the travel distance in a predetermined unit, and a second display element for displaying the travel distance in a unit smaller than the predetermined unit. The fixing assembly is to detachably attach the meter unit in the vicinity of the handle bar. The sensor is secured to a front fork of the motor cycle and disconnectably connected through a connector to the internal electric circuit. The display section and the operational section are both provided in an upper face of the meter unit. The calibration switch system comprises a calibration switch. The calibration switch has a lower height than a top face of the display section.
