It offers the following functions: total distance (odometer), graphical tachometer, speed in miles (or Km/h) (picture A). A digital speedometer connector adapter for your transmission plug is included with the Micro Digital Motorcycle Speedo. The LED unit features colored LED’s for oil pressure (red), neutral (green), high beam (blue) and turn signals (yellow) (picture B). Mounting clamps can be used to mount either the Micro Digital Motorcycle Speedo or the LED unit on 1″ handlebars (picture C). The mounting bracket allows to mount both the Micro Digital Motorcycle Speedometer and the LED unit on 1″ handlebars (picture D). Our M-Can Plus signal converter allows our Micro digital motorcycle speedometer to get information directly from the stock Harley databus (just connect it to the stock wiring loom) and to connect the LED control lights to the stock plug. All parts are sold separately.
