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.
EW000082
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. if approved
for this model), and vehicle speed. @
CE-33EEW000083
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. @

6 Tire inspection
Always check the tires before operating
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 immediately and have
the tire replaced.
EW000095
WARNING
@ Operating the motorcycle with ex-
cessively worn tires decrease riding
stability and can lead to loss of con-
trol. Have excessively worn tires re-
placed by a Yamaha dealer
immediately. Brakes, tires, and relat-
ed wheel parts replacement should
be left to a Yamaha Service Techni-
cian. @CE-26ENOTE:@ These limits may be different by regula-
tion from country to country. If so, con-
form to the limits specified by the
regulations of your own country. @

WARNING
@ l
After extensive tests, the tires
mentioned below have been ap-
proved by Yamaha Motor Co.,
Ltd. for this model. No guaran-
tee for handling characteristics
can be given if tire combina-
tions other than what is ap-
proved are used on this
motorcycle. The front and rear
tires should be of the same
manufacture and design.
l
The use of tire valves and valve
cores other than listed below
could cause tire deflation dur-
ing extreme high speed riding.
Always use genuine parts or
their equivalent for replace-
ment.
l
Be sure to install the valve caps
securely, as these are important
to prevent air pressure leakage
during extreme high speed
riding.

CE-10E
CE-12EEAU00684
WARNING
@ This motorcycle is fitted with super
high-speed running tires. The fol-
lowing points must be observed in
order for you to make fully effective
use of these tires.l
Never fail to use the specified
tires in tire replacement. Other
tires may have a danger of
bursting at super high-speeds.
l
New tires have a relatively low
grip on the road surface until
they have been slightly worn.
Therefore, approximately 100 km
should be traveled at normal
speed before any high-speed
riding is done.
l
Before any high-speed runs, the
tires should be warmed-up suf-
ficiently.
l
Always inflate to the correct tire
pressure according to the oper-
ating conditions.

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.
EAU00712
Rear brake pedal height
adjustmentThe top of the brake pedal should be
positioned 40 mm below the top of the
footrest. If not, ask a Yamaha dealer to
adjust it.
EW000109
WARNING
@ A soft or spongy feeling in the brake
pedal can indicate the presence of
air in the brake system. This air
must be removed by bleeding the
brake system before the motorcycle
is operated. Air in the system will
cause greatly diminished braking
capability and can result in loss of
control and an accident. Have a
Yamaha dealer inspect and bleed
the system if necessary. @

Brake light switch adjustmentThe rear brake light switch is activated
by the brake pedal and is properly ad-
justed when the brake light comes on
just before braking takes effect. Adjust
the brake light switch as follows.
1. Remove panel A. (See page 6-5
for panel removal and installation
procedures.)
2. Hold the switch body so it does not
rotate while turning the adjusting
nut.3. Turn the adjusting nut in
direction
a to make the brake
light come on earlier.
Turn the adjusting nut in
direction
b to make the brake
light come on later.
EAU00715
Checking the front and rear
brake padsA wear indicator is provided on each
brake. This indicator allows checking of
brake pad wear without disassembling
the brake. Apply the brake and inspect
the wear indicator. If the indicator is
ALMOST in contact with the disc plate,
ask a Yamaha dealer to replace the
pads.

Inspecting the brake fluid levelInsufficient brake fluid may let air enter
the brake or clutch system, possibly
causing them to become ineffective.
Before riding, check that the brake fluid
is above the minimum level and fill
when necessary. Low brake fluid levels
may indicate worn brake pads and/or
fluid leakage. If the brake fluid level is
low, be sure to inspect the brake pads
for wear and the brake and clutch sys-
tems for leakage.NOTE:The rear master cylinder is located be-
hind panel A.
Observe these precautions:l
When checking the fluid level,
make sure the top of the master
cylinder is level by turning the han-
dlebars.
l
Use only the designated quality
brake fluid. Otherwise, the rubber
seals may deteriorate, causing
leakage and poor brake or clutch
performance.
l
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor brake or clutch perfor-
mance.
l
Be careful that water does not en-
ter the master cylinder when refill-
ing. Water will significantly lower
the boiling point of the fluid and
may result in vapor lock.
l
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
l
Have a Yamaha dealer check the
cause if the brake fluid level goes
down.

Brake fluid replacementThe brake fluid should be replaced only
by trained Yamaha service personnel.
Have the Yamaha dealer replace the
following components during periodic
maintenance or when they are dam-
aged or leaking:l
oil seals (every two years)
l
brake hoses (every four years)

Drive chain slack checkNOTE:@ Spin the wheel several times and find
the tightest position of the chain. Check
and/or adjust the chain slack while it’s
in this tightest position. @Inspect the drive chain when the motor-
cycle is on the centerstand. Check the
slack at the position shown in the illus-
tration. Normal slack is approximately
20 ~ 30 mm. If the slack exceeds
30 mm, adjust.
EAU01251
Drive chain slack adjustment1. Loosen the axle nut.
2. Loosen the locknuts on each side.
To tighten the chain, turn the chain
adjusting bolts in direction
a.
To loosen the chain, turn the ad-
justing bolts in direction
b and
push the wheel forward. Turn each
adjusting bolt exactly the same
amount to maintain correct axle
alignment. There are marks on
each side of the swingarm. Use
these marks to align the rear
wheel.

Keep the slack within the specified
limits. @3. After adjusting, tighten the lock-
nuts. Then tighten the axle nut to
the specified torque.
EAU03006
Drive chain lubricationThe chain consists of many parts which
work with each other. If the chain is not
maintained properly, it will wear out
quickly. Therefore, the chain must be
serviced regularly. This service is es-
pecially necessary when riding in dusty
areas. This motorcycle is equipped
with a sealed type chain. Steam clean-
ing, high-pressure washers, and sol-
vents can damage the drive chain, so
do not use these for cleaning it. Use
only kerosene to clean the drive chain.
Wipe it dry, and thoroughly lubricate it
with SAE 30 ~ 50W motor oil. Do not
use any other lubricants on the drive
chain. They may contain solvents that
could damage the sealed chain.
EC000097
CAUTION:@ Be sure to oil the chain after wash-
ing the motorcycle or riding in the
rain. @

possible to prevent unsafe condi-
tions. @Lubricate the cables and cable ends. If
a cable does not operate smoothly, ask
a Yamaha dealer to replace it. Tightening torque:
