Front brake pads
Each front brake pad is provided with
a wear indicator groove, which allows
you to check the brake pad wear
without having to disassemble the
brake. To check the brake pad wear,
check the wear indicator groove. If a
brake pad has worn to the point that
the wear indicator groove has almost
disappeared, have a Yamaha dealer
replace the brake pads as a set.

Checking the brake fluid
level
Brake fluid level, checkingInsufficient brake fluid may allow air
to enter the brake system, possibly
causing it to become ineffective.
Before riding, check that the brake
fluid is above the minimum level mark
and replenish if necessary. A low
brake fluid level may indicate worn
brake pads and/or brake system
leakage. If the brake fluid level is low,
be sure to check the brake pads for
wear and the brake system for leak-
age.

Rear brake pads
Check each rear brake pad for dam-
age and measure the lining thick-
ness. If a brake pad is damaged or if
the lining thickness is less than
0.8 mm, have a Yamaha dealer
replace the brake pads as a set.

8When checking the fluid level,
make sure that the top of the
brake fluid reservoir is level.
8Use only the recommended qual-
ity brake fluid, otherwise the rub-
ber seals may deteriorate, caus-
ing leakage and poor braking
performance.

Changing the brake fluidBrake fluid, changingHave a Yamaha dealer change the
brake fluid at the intervals specified in
the NOTE after the periodic mainte-
nance and lubrication chart. In addi-
tion, have the oil seals of the brake
master cylinder and caliper as well as
the brake hose replaced at the inter-
vals listed below or whenever they
are damaged or leaking.
8Oil seals: Replace every two
years.
8Brake hose: Replace every four
years. 8Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking perfor-
mance.
8Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of
the fluid and may result in vapor
lock.
8Brake fluid may deteriorate paint-
ed surfaces or plastic parts.
Always clean up spilled fluid
immediately.
8As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if
the brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause.

Drive chain slackDrive chain slackThe drive chain slack should be
checked before each ride and adjust-
ed if necessary.
To check the drive chain slack
Checking1. Place the motorcycle on a level
surface and hold it in an upright
position.
NOTE:
When checking and adjusting the
drive chain slack, the motorcycle
should be positioned straight up and
there should be no weight on it.EAU04372
To adjust the drive chain slackAdjusting1. Loosen the axle nut, the brake
caliper bracket bolt and the lock-
nut on each side of the
swingarm.
2. To tighten the drive chain, turn
the adjusting bolt on each side of
the swingarm in direction a. To
loosen the drive chain, turn the
adjusting bolt on each side of the
swingarm in direction b, and
then push the rear wheel for-
ward.

Improper drive chain slack will
overload the engine as well as
other vital parts of the motorcycle
and can lead to chain slippage or
breakage. To prevent this from
occurring, keep the drive chain
slack within the specified limits.

Lubricating the drive chainDrive chain, lubricatingThe drive chain must be cleaned and
lubricated at the intervals specified in
the periodic maintenance and lubrica-
tion chart, otherwise it will quickly
wear out, especially when riding in
dusty or wet areas. Service the drive
chain as follows.
EC000097
cC
The drive chain must be lubricated
after washing the motorcycle or
riding in the rain.
1. Clean the drive chain with
kerosene and a small soft brush.

cC
To prevent damaging the O-rings,
do not clean the drive chain with
steam cleaners, high-pressure
washers or inappropriate solvents.
3. Tighten the locknuts, and then
tighten the axle nut and the
brake caliper bracket bolt to the
specified torques.
Tightening torque:
Axle nut:
150 Nm (15.0 m·kgf)

Do not use engine oil or any other
lubricants for the drive chain, as
they may contain substances that
could damage the O-rings.

Damage to the outer sheath may
interfere with proper cable opera-
tion and will cause the inner cable
to rust. Replace a damaged cable
as soon as possible to prevent
unsafe conditions.

BatteryBatteryThis 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
cC
Never attempt to remove the bat-
tery cell seals, as this would per-
manently damage the battery.
8Batteries produce explosive
hydrogen gas. Therefore, keep
sparks, flames, cigarettes,
etc., away from the battery and
provide sufficient ventilation
when charging it in an
enclosed space.
8KEEP THIS AND ALL BATTER-
IES OUT OF THE REACH OF
CHILDREN.
To charge the battery
Have a Yamaha dealer charge the
battery as soon as possible if it
seems to have discharged. Keep in
mind that the battery tends to dis-
charge more quickly if the motorcycle
is equipped with optional electrical
accessories.
EW000116

8Electrolyte is poisonous and
dangerous since it contains
sulfuric acid, which causes
severe burns. Avoid any con-
tact with skin, eyes or clothing
and always shield your eyes
when working near batteries.
In case of contact, administer
the following FIRST AID.
9EXTERNAL: Flush with
plenty of water.
9INTERNAL: Drink large
quantities of water or milk
and immediately call a
physician.
9EYES: Flush with water for
15 minutes and seek prompt
medical attention.

6 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
installation.
4. After installation, make sure that
the battery leads are properly
connected to the battery termi-
nals.

Replacing the fusesFuses, replacingThe main fuse and the fuse box,
which contains the fuses for the indi-
vidual circuits, are located under the
seat. (See page 3-13 for seat
removal and installation procedures.)
If a fuse is blown, replace it as fol-
lows.
1. Turn the key to “OFF” and turn
off the electrical circuit in ques-
tion.

8Always keep the battery
charged. Storing a discharged
battery can cause permanent
battery damage.
8To charge a sealed-type (MF)
battery, a special (constant-
voltage) battery charger is
required. Using a conventional
battery charger will damage
the battery. If you do not have
access to a sealed-type (MF)
battery charger, have a
Yamaha dealer charge your
battery.
