Measurement mode (for calibrating
the distance-compensation tripme-
ter’s reading)
The distance-compensation tripmeter
is a feature intended to provide a more
accurate tripmeter reading for enduro
riding. Calibrating this meter in accor-
dance with the distances specified on
the enduro course map will help famil-
iarize the rider with the course. In addi-
tion, calibrating the meter may also be
necessary when using tire, wheel,
chain sprocket sizes, etc. other than
specified. For further information con-
cerning the use of this meter, please
consult your nearby Yamaha dealer.
Calibrate the distance-compensation
tripmeter as follows.
To increase the reading, push the
“SLCT 1” button. To decrease the read-
ing, push the “SLCT 2” button. Pushing and holding either button will increase
or decrease the reading continuously
until the button is released.
TIPCalibrating the reading of the dis-
tance-compensation tripmeter is possi-
ble regardless of the stopwatchoperation.

WARNING
EWA10572

Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the mo-
torcycle with excessively worn
tires decreases riding stability
and can lead to loss of control.

The replacement of all wheel-
and brake-related parts, includ-
ing the tires, should be left to a
Yamaha dealer, who has the
necessary professional knowl-
edge and experience.

It is not recommended to patch
a punctured tube. If unavoid-
able, however, patch the tube
very carefully and replace it as
soon as possible with a high-quality product.

Ride at moderate speeds after
changing a tire since the tire
surface must first be “broken
in” for it to develop its optimalcharacteristics.
