from one to the other. When set to
“ODO”, it indicates the motorcycle’s to-
tal mileage. When set to “TRIP”, it indi-
cates the motorcycle’s mileage since
the trip meter was last reset. Use the
trip meter to estimate how far you can
ride on a tank of fuel. This information
will enable you to plan fuel stops in the
future.To reset the trip meter to “0”, push the
“TRIP” button until it displays “TRIP”,
then push it once again and hold it
down for at least one second.
