The Carl Lewis MOT25 has the same console as the Roger Black Gold GM-41002. To change Miles to Kilometers you need to remove a link on the console circuit board. Remove the mains plug from the machine. Remove all of the screws from the rear of the console. I wasn't able to remove the back completely but it does pull apart wide enough to remove the jumper from the link with a pair of tweezers. You can see the link on the circuit board looking down from the top roughly in the middle of the console. Remember to save the link in case you want to change back to miles.
