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 “SE-
LECT 1” button. To decrease the read-
ing, push the “SELECT 2” button.
Pushing and holding either button will
increase or decrease the reading con-
tinuously until the button is released.
TIPCalibrating the reading of the dis-
tance-compensation tripmeter is possi-
ble regardless of the stopwatchoperation.

Tire inspection
The tires must be checked before each
ride. If the center tread depth reaches
the specified limit, if the tire has a nail or
glass fragments in it, or if the sidewall is
cracked, have a Yamaha dealer re-
place the tire immediately.
TIPThe tire tread depth limit may differ
from country to country. Always complywith the local regulations.
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.
Tire information
This model is equipped with tube tires. Tires age, even if they have not been
used or have only been used occasion-
ally. Cracking of the tread and sidewall
rubber, sometimes accompanied by
carcass deformation, is an evidence of
ageing. Old and aged tires shall be
checked by tire specialists to ascertain
their suitability for further use.
WARNING
EWA10462
The front and rear tires should be of
the same make and design, other-
wise the handling characteristics of
the vehicle may be different, whichcould lead to an accident.

ed below have been approved for this
