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.

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. To ad-
just the rear brake light switch, hold the
switch body so it does not rotate while
turning the adjusting nut.
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.1. Brake light switch

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 AL-
MOST in contact with the disc plate,
ask a Yamaha dealer to replace the
pads.1. Wear indicatorFront

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
brake system leakage. If the brake lev-
el is low, be sure to inspect the brake
pads for wear or brake system for leak-
age.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.
EAU00742
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 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. @

Replace damaged cables as soon as
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.

EW000115
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.

CAUTION:@ If any damage or unsmooth move-
ment is found with the front fork,
consult a Yamaha dealer. @
EAU00794
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.

quer thinner. @4. Install the bulb holder cover and
reconnect the headlight connec-
tors. If the headlight beam adjust-
ment is necessary, ask a Yamaha
