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 en-
able you to plan future fuel stops.

TIP

The annual checks must be performed every year, except if a kilometer-based maintenance, or for the UK, a
mileage-based maintenance, is performed instead.


From 30000 km (17500 mi), repeat the maintenance intervals starting from 6000 km (3500 mi).


Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and technicalskills.
