Calibration.

How does one calibrate a speedometer?

The GPS and my bike do not agree.  120KPH on the bike speedo is 107 according to the Garmin , which happens to agree exactly with the speedo in my Toyota.  The good news is that as long as I keep an eye on the needle, I should not be getting a speeding ticket. It could be a disaster if the error was the other way round.

On the other hand, according to my bike odometer, I rode 401 km from Bindoon to home, whereas Google says the distance is 362 km.    That is quite a variation and I suspect it means I am adding mileage and depreciation to my bike at an excessive rate.  What can be done about that?

    A little bird told me that as part of the ADR requirements all speedos need to over-estimate the speed, but it could be an urban myth. How to fix it? No idea.

    I have had the same problem, I have installed a Yellow Box . It goes in line with the speedo connections and is infinitely adjustable.
