Saddlebags and travel trunk
EWA00021
WARNING
@ l
Always be sure to close and
lock the saddlebags and travel
trunk securely before operating
the motorcycle.
l
Distribute weight evenly on
each side of the motorcycle.
l
Never exceed the maximum
loading limit of 9 kg in each sad-
dlebag and the travel trunk. Im-
proper loading or overloading
can cause vehicle handling
problems leading to an accident
or personal injury.
l
Read the Owner’s manual for
important loading and tire pres-
sure information.
l
Total weight of rider, passen-
ger, accessories and cargo
must not exceed the motorcycle
load capacity shown in the
Owner’s Manual.
l
Never ride above 120 km/h with
travel trunk and/or saddlebags
because handling could be af-
fected. This maximum speed
may be reduced by such factors
as improper loading, poor tire
or overall motorcycle condi-
tions, poor road surfaces or ad-
verse weather conditions.

2. Remove the valve cap from each
fork leg.
3. Check the air pressure using the
air pressure gauge in the owner’s
tool kit, and adjust it if necessary.
Increasing the air pressure in-
creases the spring preload, de-
creasing the air pressure
decreases the spring preload.
To increase the air pressure, use
an air pump or compressed air.
To decrease the air pressure, re-
lease the air by pushing the valve.

SidestandThis model is equipped with an ignition
circuit cut-off system. The motorcycle
must not be ridden when the sidestand
is down. The sidestand is located on
the left side of the frame. (Refer to
page 6-1 for an explanation of this sys-
tem.)
EW000044
WARNING
@ This motorcycle must not be operat-
ed with the sidestand in the down
position. If the stand is not properly
retracted, it could contact the
ground and distract the operator, re-
sulting in a possible loss of control.
Yamaha has designed into this
motorcycle a lockout system to as-
sist the operator in fulfilling the re-
sponsibility of retracting the
sidestand. Please check carefully
the operating instructions listed be-
low and if there is any indication of a
malfunction, return the motorcycle
to a Yamaha dealer immediately for
repair. @

TiresTo ensure maximum performance,
long service and safe operation, note
the following:
Tire air pressure
Always check and adjust the tire pres-
sure before operating the motorcycle.
EWA00018
WARNING
@ Tire 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 ac-
cording to total weight of cargo,
rider, passenger, and accessories
(fairing, saddlebags, etc.). @CE-37EEW000083
WARNING
@ Proper loading of your motorcycle
is important for several characteris-
tics 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 motorcycle, and dis-
tribute the weight evenly from side
to side. Properly adjust the suspen-
sion for your load, and check the
condition and pressure of your tires.
NEVER OVERLOAD YOUR MOTOR-
CYCLE. 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 over-
loaded motorcycle could cause tire
damage, an accident, or even injury. @

This motorcycle is equipped with tube-
less tires, tire valves and cast wheels.
EW000132
WARNING
@ After extensive tests, the tires men-
tioned 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 ap-
proved are used on this motorcycle.
The front and rear tires should be of
the same manufacture and design.
Always use the tire valves and valvecores listed below. Be sure to install
the valve caps securely, as these
are important to prevent air pres-
sure leakage.

WheelsTo ensure maximum performance,
long service, and safe operation, note
the following:l
Always inspect the wheels before
a ride. Check for cracks, bends or
warpage of the wheels. If any ab-
normal condition exists in a wheel,
consult a Yamaha dealer. Do not
attempt even small repairs to the
wheel. If a wheel is deformed or
cracked, it must be replaced.
l
Tires and wheels should be bal-
anced whenever either one is
changed or replaced. Failure to
have a wheel balanced can result
in poor performance, adverse han-
dling characteristics and short-
ened tire life.
l
Ride at moderate speeds after
changing a tire since the tire sur-
face must first be broken in for it to
develop its optimal characteristics.

WARNING
@ Securely support the motorcycle so
there is no danger of it falling over. @Check for scratches or damage on the
inner tube and excessive oil leakage
from the front fork.
Operation check
1. Place the motorcycle on a level
place.
2. Hold the motorcycle in an upright
position and apply the front brake.
3. Push down hard on the handle-
bars several times and check if the
fork rebounds smoothly.

Steering inspectionPeriodically inspect the condition of the
steering. Worn out or loose steering
bearings may be dangerous. Place a
stand under the engine to raise the
front wheel off the ground. Hold the
lower end of the front forks and try to
move them forward and backward. If
any free play can be felt, ask a Yamaha
dealer to inspect and adjust the steer-
ing. Inspection is easier if the front
wheel is removed.

BatteryThis motorcycle is equipped with a
sealed-type battery. Therefore it is not
necessary to check the electrolyte or fill
the battery with distilled water.l
If the battery seems to have dis-
charged, consult a Yamaha deal-
er.
l
If the motorcycle is equipped with
optional electrical accessories, the
battery tends to discharge more
quickly, so be sure to recharge it
periodically.
