9 Owners are personally responsible for their vehicleÕs condition. Your motorcycleÕs vital functions can start to deteriorate
quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements). Any damage, fluid
leak or loss of tire pressure could have serious consequences. Therefore, it is very important that, in addition to a thor-
ough visual inspection, you check the following points before each ride.

TiresTo ensure maximum performance,
long service and safe operation, note
the following:
Tire air pressure
Always check and adjust the tire
pressure before operating the motor-
cycle.
EW000082
wTire inflation pressure should be
checked and adjusted when the
temperature of the tire equals the
ambient air temperature. Tire infla-
tion pressure must be adjusted
according to total weight of cargo,
rider, passenger, and accessories
(fairing, saddlebags, etc. if
approved for this model), and vehi-
cle speed.

wProper loading of your motorcycle
is important for several character-
istics of your motorcycle, such as
handling, braking, performance
and safety. Do not carry loosely
packed items that can shift.
Securely pack your heaviest items
close to the center of the motorcy-
cle, and distribute the weight even-
ly from side to side. Properly
adjust the suspension for your
load, and check the condition and
pressure of your tires. NEVER
OVERLOAD YOUR MOTORCYCLE.
Make sure the total weight of the
cargo, rider, passenger, and
accessories (fairing, saddlebags,
etc. if approved for this model)
does not exceed the maximum
load of the motorcycle. Operation
of an overloaded motorcycle could
cause tire damage, an accident, or
even injury.
Tire inspection
Always check the tires before operat-
ing the motorcycle. If center tread
depth reaches the limit as shown, if
the tire has a nail or glass fragments
in it, or if the side wall is cracked,
contact a Yamaha dealer immediate-
ly and have the tire replaced.
EW000078
wAfter extensive tests, the tires
mentioned below have been
approved by Yamaha Motor Co.,
Ltd. for this model. No guarantee
for handling characteristics can be
given if tire combinations other
than what is approved are used on
this motorcycle. The front and rear
tires should be of the same manu-
facture and design.

96.Lubricate all control cables and
the pivoting points of all levers
and pedals as well as of the
sidestand/centerstand.
7.Check and, if necessary, correct
the tire air pressure, then raise
the motorcycle so that both of its
wheels are off the ground.
Alternatively, turn the wheels a
little every month in order to pre-
vent the tires from becoming
degraded in one spot.
8.Cover up the muffler outlet with a
plastic bag to prevent moisture
from entering.9.Remove the battery and fully
charge it. Store it in a cool, dry
place and recharge it once a
month. Do not store the battery
in an excessively cold or warm
place (less than 0 ¡C or more
than 30 ¡C). For more informa-
tion, see ÒBattery storageÓ in the
chapter ÒPERIODIC MAINTE-
NANCE AND MINOR
REPAIRSÓ.
NOTE:
Make any necessary repairs before
storing the motorcycle.
