As the brake pads wear, it is normal for
the brake fluid level to gradually go
down.

A low brake fluid level may indicate
worn brake pads or brake system
leakage; therefore, be sure to
check the brake pads for wear and
the brake system for leakage.

If the brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause before further rid-
ing.WARNING
EWA15991
Improper maintenance can result in
loss of braking ability. Observe
these precautions:

Insufficient brake fluid may al-
low air to enter the brake sys-
tem, reducing braking
performance.

Clean the filler cap before re-
moving. Use only DOT 4 brake
fluid from a sealed container.

Use only the specified brake flu-
id; otherwise, the rubber seals
may deteriorate, causing leak-
age.

Refill with the same type of
brake fluid. Adding a brake fluid
other than DOT 4 may result in a
harmful chemical reaction.

Be 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 vaporlock.
EAU22734
Changing the brake fluidHave a Yamaha dealer change the
brake fluid every 2 years. In addition,
have the seals of the master cylinders
and brake calipers, as well as the brake
hoses replaced at the intervals listed
below or sooner if they are damaged or
leaking.
Brake seals: every 2 years

Brake hoses: every 4 years

gasoline, rust removers, brake
fluid, or antifreeze, etc.
Before washing 1. Park the vehicle out of direct sun- light and allow it to cool. This will
help avoid water spots.
2. Make sure all caps, covers, electri- cal couplers and connectors are
tightly installed.
3. Cover the muffler end with a plas- tic bag and a strong rubber band.
4. Pre-soak stubborn stains like in- sects or bird droppings with a wet
towel for a few minutes.
5. Remove road grime and oil stains with a quality degreasing agent
and a plastic-bristle brush or
sponge. NOTICE: Do not use de-
greasing agent on areas requir-
ing lubrication such as seals,
gaskets, and wheel axles. Fol-
low product instructions.
[ECA26290]
Washing 1. Rinse off any degreaser and spray down the vehicle with a garden
hose. Use only enough pressure to do the job. Avoid spraying water
directly into the muffler, instrument
panel, air inlet, or other inner areas
such as underseat storage com-
partments.
2. Wash the vehicle with a quality au- tomotive-type detergent mixed
with cool water and a soft, clean
towel or sponge. Use an old tooth-
brush or plastic-bristle brush for
hard-to-reach places. NOTICE:
Use cold water if the vehicle has
been exposed to salt. Warm wa-
ter will increase salt’s corrosive
properties.
[ECA26301]
3. For windshield-equipped vehicles: Clean the windshield with a soft
towel or sponge dampened with
water and a pH neutral detergent.
If necessary, use a high-quality
windshield cleaner or polish for
motorcycles. NOTICE: Never use
any strong chemicals to clean
the windshield. Additionally,
some cleaning compounds for
plastic may scratch the wind-
shield, so be sure to test all
cleaning products before gener-
al application.
[ECA26310]
4. Rinse off thoroughly with clean wa- ter. Be sure to remove all deter-
gent residues, as they can be
harmful to plastic parts.
After washing 1. Dry the vehicle with a chamois or absorbent towel, preferably micro-
fiber terrycloth.
2. For drive chain-equipped models: Dry and then lubricate the drive
chain to prevent rust.
3. Use a chrome polish to shine chrome, aluminum, and stainless
steel parts. Often the thermally in-
duced discoloring of stainless steel
exhaust systems can be removed
through polishing.
4. Apply a corrosion protection spray on all metal parts including chrome
or nickel-plated surfaces.
WARNING! Do not apply
silicone or oil spray to seats,
hand grips, rubber foot pegs or
tire treads. Otherwise these
parts will become slippery,
which could cause loss of con-
trol. Thoroughly clean the sur-
faces of these parts before
