Some of the mz bikes made it to the usa with metric speedometers
my saxon tour for one
to convert to mph when riding look at number say your doing 90k
drop the zero and do the math as 9x6 =54
or your doing 30kph its 3x6=18
or 110k 11x6=66
its not to far off and may keep you from a speeding ticket
error is about 2 mph at 60 to 65mph
the speedometer is off more than that most times
