WARNING
_ Because loading has an enormous
impact on the handling, braking, per-
formance and safety characteristics
of your motorcycle, you should keep
the following precautions in mind. l
NEVER OVERLOAD THE
MOTORCYCLE! Operation of an
overloaded motorcycle may re-
sult in tire damage, loss of con-
trol, or severe injury. Make sure
that the total weight of rider, pas-
senger, cargo, and accessories
does not exceed the specified
maximum load for the vehicle.
l
Do not carry along loosely
packed items, which can shift
during a ride.
l
Securely pack the heaviest
items close to the center of the
motorcycle and distribute the
weight evenly on both sides.
l
Adjust the suspension and tire
air pressure with regard to the
load.
l
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. _

WARNING
_ l
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.
l
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.

Tire information
This motorcycle is equipped with cast
wheels and tubeless tires with valves.
EW000080
WARNING
_ l
The front and rear tires should
be of the same make and de-
sign, otherwise the handling
characteristics of the motor-
cycle cannot be guaranteed.
l
After extensive tests, only the
tires listed below have been ap-
proved for this model by
Yamaha Motor Co., Ltd.
l
Always make sure that the valve
caps are securely installed to
prevent air pressure leakage.
l
Use only the tire valves and
valve cores listed below to
avoid tire deflation during a
high-speed ride.

WARNING
@ This motorcycle is fitted with super-
high-speed tires. Note the following
points in order to make the most ef-
ficient use of these tires.l
Use only the specified replace-
ment tires. Other tires may run
the danger of bursting at super
high speeds.
l
Brand-new tires can have a rela-
tively poor grip on certain road
surfaces until they have been
“broken in”. Therefore, it is ad-
visable before doing any high-
speed riding to ride conserva-
tively for approximately 100 km
after installing a new tire.
l
The tires must be warmed up
before a high-speed run.
l
Always adjust the tire air pres-
sure according to the operating
conditions.

WARNING
@ A soft or spongy feeling in the brake
pedal can indicate the presence of
air in the hydraulic system. If there
is air in the hydraulic system, have a
Yamaha dealer bleed the system be-
fore operating the motorcycle. Air in
the hydraulic system will diminish
the braking performance, which
may result in loss of control and an
accident. @

Battery This motorcycle is equipped with a
sealed-type (MF) battery, which does
not require any maintenance. There is
no need to check the electrolyte or to
add distilled water.
EC000101
CAUTION:@ Never attempt to remove the battery
cell seals, as this would permanent-
ly damage the battery. @
EW000116
WARNING
@ l
Electrolyte is poisonous and
dangerous since it contains sul-
furic acid, which causes severe
burns. Avoid any contact with
skin, eyes or clothing and al-
ways shield your eyes when
working near batteries. In case
of contact, administer the fol-
lowing FIRST AID.
• EXTERNAL: Flush with plenty
of water.
• INTERNAL: Drink large quan-
tities of water or milk and im-
mediately call a physician.
• EYES: Flush with water for
15 minutes and seek prompt
medical attention.
l
Batteries produce explosive hy-
drogen gas. Therefore, keep
sparks, flames, cigarettes, etc.,
away from the battery and pro-
vide sufficient ventilation when
charging it in an enclosed
space.
l
KEEP THIS AND ALL BATTER-
IES OUT OF THE REACH OF
CHILDREN.
@To charge the battery
Have a Yamaha dealer charge the bat-
tery as soon as possible if it seems to
have discharged. Keep in mind that the
battery tends to discharge more quickly
if the motorcycle is equipped with op-
tional electrical accessories.
To store the battery
1. If the motorcycle will not be used
for more than one month, remove
the battery, fully charge it, and
then place it in a cool, dry place.
2. If the battery will be stored for
more than two months, check it at
least once a month and fully
charge it if necessary.
3. Fully charge the battery before in-
stallation.
4. After installation, make sure that
the battery leads are properly con-
nected to the battery terminals.
