Speedometer unit The speedometer unit is equipped
with a speedometer, an odometer
and a tripmeter. The speedometer
shows riding speed. The odometer
shows the total distance traveled.
The tripmeter shows the distance
traveled since it was last set to zero
with the reset knob. The tripmeter
can be used to estimate the distance
that can be traveled with a full tank of
fuel. This information will enable you
to plan future fuel stops.1. Speedometer
