Matte color caution NOTICE
ECA15192
Some models are equipped with
matte colored finished parts. Be
sure to consult a Yamaha dealer for
advice on what products to use be-
fore cleaning the vehicle. Using a
brush, harsh chemical products or
cleaning compounds when cleaning
these parts will scratch or damage
their surface. Wax also should not
be applied to any matte colored fin-
ished parts.
EAU40635
Care While the open design of a motorcycle
reveals the attractiveness of the tech-
nology, it also makes it more vulnera-
ble. Rust and corrosion can develop
even if high-quality components are
used. A rusty exhaust pipe may go un-
noticed on a car, however, it detracts
from the overall appearance of a motor-
cycle. Frequent and proper care does
not only comply with the terms of the
warranty, but it will also keep your mo-
torcycle looking good, extend its life
and optimize its performance.
Before cleaning1. Cover the muffler outlet with a plastic bag after the engine has
cooled down.
2. Make sure that all caps and covers as well as all electrical couplers
and connectors, including the
spark plug cap, are tightly in-
stalled.
3. Remove extremely stubborn dirt, like oil burnt onto the crankcase,
with a degreasing agent and a
brush, but never apply such prod- ucts onto seals, gaskets and wheel
axles. Always rinse the dirt and de-
greaser off with water.
Cleaning
NOTICE
ECA17110
●
Avoid using strong acidic wheel
cleaners, especially on spoked
wheels. If such products are
used on hard-to-remove dirt, do
not leave the cleaner on the af-
fected area any longer than in-
structed. Also, thoroughly rinse
the area off with water, immedi-
ately dry it, and then apply a cor-
rosion protection spray.
●
Improper cleaning can damage
plastic parts (such as cowlings,
panels, etc.) and the mufflers.
Use only a soft, clean cloth or
sponge with water to clean plas-
tic. However, if the plastic parts
cannot be thoroughly cleaned
with water, diluted mild deter-
gent with water may be used. Be
sure to rinse off any detergent
residue using plenty of water, as
it is harmful to plastic parts.

●
Do not use any harsh chemical
products on plastic parts. Be
sure to avoid using cloths or
sponges which have been in
contact with strong or abrasive
cleaning products, solvent or
thinner, fuel (gasoline), rust re-
movers or inhibitors, brake flu-
id, antifreeze or electrolyte.
●
Do not use high-pressure wash-
ers or steam-jet cleaners since
they cause water seepage and
deterioration in the following ar-
eas: seals (of wheel and swing-
arm bearings, fork and brakes),
electric components (couplers,
connectors, and switches),
breather hoses and vents.
After normal useRemove dirt with warm water, a mild
detergent, and a soft, clean sponge,
and then rinse thoroughly with clean
water. Use a toothbrush or bottlebrush
for hard-to-reach areas. Stubborn dirt
and insects will come off more easily if
the area is covered with a wet cloth for
a few minutes before cleaning.After riding in the rain or near the sea
Since sea salt is extremely corrosive,
carry out the following steps after each
ride in the rain or near the sea.
1. Clean the motorcycle with cold wa- ter and a mild detergent, after the
engine has cooled down.
NOTICE: Do not use warm water
since it increases the corrosive
action of the salt.
[ECA10791]
2. Apply a corrosion protection spray on all metal, including chrome- and
nickel-plated, surfaces to prevent
corrosion.
After cleaning 1. Dry the motorcycle with a chamois or an absorbing cloth.
2. Use a chrome polish to shine chrome, aluminum and stainless-
steel parts.
3. To prevent corrosion, it is recom- mended to apply a corrosion pro-
tection spray on all metal,
including chrome- and nickel-plat-
ed, surfaces.
4. Use spray oil as a universal clean- er to remove any remaining dirt. 5. Touch up minor paint damage
caused by stones, etc.
6. Wax all painted surfaces.
7. Let the motorcycle dry completely before storing or covering it.
WARNING
EWA14501
Contaminants on the brakes or tires
can cause loss of control.●
Make sure that there is no oil or
wax on the tires.
●
If necessary, wash the tires with
warm water and a mild deter-
gent. Before riding at higher
speeds, test the motorcycle’s
braking performance and cor-
nering behavior.
NOTICE
ECA10800
●
Apply spray oil and wax spar-
ingly and make sure to wipe off
any excess.
●
Never apply oil or wax to any
rubber and plastic parts, but
treat them with a suitable care
product.

e. Remove the spark plug cap
from the spark plug, and then
install the spark plug and the
spark plug cap. WARNING! To
prevent damage or injury
from sparking, make sure to
ground the spark plug elec-
trodes while turning the en-
gine over.
[EWA10951]
6. Lubricate all control cables and the pivoting points of all levers as well
as of the centerstand.
7. Check and, if necessary, correct the tire air pressure, and then lift
the motorcycle so that both of its
wheels are off the ground. Alterna-
tively, turn the wheels a little every
month in order to prevent the tires
from becoming degraded in one
spot.
8. Cover the muffler outlet with a plastic bag to prevent moisture
from entering it.TIPMake any necessary repairs before
storing the motorcycle.
