All MPH speedometers have these KPH range markings but yeah they do seem off. 100kph should be centered at around 62 MPH, but as you can see here it starts at 64 MPH or centered around 66 MPH
THREADQuote:
the marking are kinda like a guestimate for where it should be, 60mph = 96 kph
but even on yhe dash in my sedan, origianl kph dash, it has the mph below it and they dont really line up too well
according to my convertion thing, 100kph =62.1 mph
and on the dash its at about 64 mph, see pic below
But it is possible to fix, see tech article:
