Securely pack the heaviest
items close to the center of the
motorcycle and distribute the
weight evenly on both sides.


Adjust the suspension and tire
air pressure with regard to the
load.


Check the tire condition and air
pressure before each ride.
_
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 side-
wall is cracked, have a Yamaha dealer
replace the tire immediately.CE-08ENOTE:_ The tire tread depth limits may differ
from country to country. Always comply
with the local regulations. _
EW000079
WARNING
_

Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the
motorcycle with excessively
worn tires decreases riding sta-
bility 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.
