ABSTRACT:
A motorcycle speedometer assembly includes a casing, and a display face on the casing; a first rotary indicator at the display face and rotatable about a first axis, there being first speed indicating indicia on the display first face with which the indicator registers as it rotates about the axis; a first drive responsive to motorcycle forward speed and connected with the first indicator for rotating the indicator in proportion to motorcycle speed to register with corresponding first indicia; and a second indicator at the display face and rotatable about a second axis to indicate motorcycle engine RPM, the second axis offset from the first axis, there being second indicia on the display face with which the second indicator registers as it rotates about the second axis, the second indicia indicating tachometer increasing values of RPM; and a second drive responsive to motorcycle engine RPM and connected with the second indicator for rotating the second indicator in proportion to engine speed to register with corresponding second indicia; also, a rearwardly elongated, upwardly bulged, wedge shaped carrier supports the casing, the carrier having an upper surface substantially flush with said face, the carrier tapering rearwardly from said casing to incline the display face toward the motorcycle rider.
