5-PRE-OPERATION CHECKSOwners are personally responsible for their vehicle’s condition. Your motorcycle’s vital functions can start to deteriorate
quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements). Any damage, fluid leak or
loss of tire pressure could have serious consequences. Therefore, it is very important that, in addition to a thorough visual in-
spection, you check the following points before each ride.

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.
EWA00018
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.). @CE-37EEW000083
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. @

7 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.
EW000079
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. @

7Tire information
This motorcycle is equipped with tube-
less tires, tire valves and cast wheels.
EW000132
WARNING
@ After extensive tests, the tires men-
tioned below have been approved
by Yamaha Motor Co., Ltd. for this
model. No guarantee for handling
characteristics can be given if tire
combinations other than what is ap-
proved are used on this motorcycle.
The front and rear tires should be of
the same manufacture and design.
Always use the tire valves and valvecores listed below. Be sure to install
the valve caps securely, as these
are important to prevent air pres-
sure leakage.
@CE-41E
CE-42EEAU01230
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.

8After riding in the rain, near the sea or
on salt-sprayed roadsSince sea salt or salt sprayed on the
roads in the winter are extremely corro-
sive in combination with water, carry
out the following steps after each ride
in the rain, near the sea or on salt-
sprayed roads. (Salt sprayed in the
winter may remain on the roads well
into spring.)
1. Clean your motorcycle with cold
water and soap after the engine
has cooled down.
ECA00012
CAUTION:@ Do not use warm water since it in-
creases the corrosive action of the
salt. @2. Be sure to apply a corrosion pro-
tection spray on all (even chrome-
and nickel-plated) metal 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, including the exhaust
system. (Even the thermally in-
duced discoloring of stainless-
steel exhaust systems can be re-
moved through polishing.)
3. To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all (even chrome-
and nickel-plated) metal 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 it or covering it.
EWA00001
WARNING
@ Make sure that there is no oil or wax
on the brakes and tires. If neces-
sary, clean the brake discs and lin-
ings with a regular brake disc
cleaner or acetone, and wash the
tires with warm water and mild soap.
Then, carefully test the motorcycle
for its braking performance and cor-
nering behavior. @

8a. Remove the spark plug caps and
spark plugs.
b. Pour a teaspoonful of engine oil
into each spark plug bore.
c. Install the spark plug caps onto the
spark plugs and place the spark
plugs on the cylinder head so that
the electrodes are grounded. (This
will limit sparking during the next
step.)
d. Turn the engine over several times
with the starter. (This will coat the
cylinder walls with oil.)
e. Remove the spark plug caps from
the spark plugs, install the spark
plugs and then the spark plug
caps.
EWA00003
WARNING
@ When turning the engine over, be
sure to ground the spark plug elec-
trodes to prevent damage or injury
from sparking. @
6. Lubricate all control cables and
the pivoting points of all levers and
pedals as well as of the sidestand/
centerstand.
7. Check and, if necessary, correct
the tire air pressure, then raise 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 up the muffler outlets with
plastic bags to prevent moisture
from entering.9. Remove the battery and fully
charge it. Store it in a cool, dry
place and recharge it once a
month. Do not store the battery in
an excessively cold or warm place
(less than 0 °C or more than
30 °C). For more information, see
“Battery storage” in the chapter
“PERIODIC MAINTENANCE AND
MINOR REPAIRS”.
NOTE:@ Make any necessary repairs before
storing the motorcycle. @
