It’s an offence in NSW to interfere with an odometer reading, and the Motor Dealers and Repairers Act 2013 deems interference to be: … removing or replacing the odometer. rendering the odometer inoperative or inaccurate by any means whatsoever.

If you’re talking about the trip odometer, there should be a knob sticking out from the speedometer if you have analog gauges, or a reset button if your setup is digital. Just select “trip miles” or “Trip A/trip B” and push the knob/reset button until the numbers go to zero.
Press and hold the calibration button located on the speedometer, start the vehicle, and then release the button. Press that button again and then take the test drive. Once you have driven the distance needed, press the button once more and the speedometer will calibrate itself to accommodate the new tire size.
Most current motorcycle speedometers use a sensor triggered by the teeth of a transmission gear or a similar dedicated ring or by the slots in an ABS wheel ring. These sensors send a square-wave signal to the ECU, which calculates speed from the frequency of the signal.
The Speedometer Vehicle Speed Sensor (VSS) is located in the transmission housing on the passenger side output flange. Automatic Transmission The Vehicle Speed Sensor (VSS) is located on the right side of the transmission near the output shaft.
Faulty Fuse/Bad Wiring: In very wet conditions, it is possible for exposed wires to get wet and short out, causing a fuse to blow. When the fuse for your speedometer stops working, it can cause the speedometer to drop to zero.
