TiresTo maximize the performance, dura-
bility, and safe operation of your
scooter, note the following points
regarding the specified tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
EW000082
w8The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the tempera-
ture of the tires equals the
ambient temperature).
8The tire air pressure must be
adjusted in accordance with
the riding speed and with the
total weight of rider, passen-
ger, cargo, and accessories
approved for this model.
EWA00040
wBecause loading has an enormous
impact on the handling, braking,
performance and safety character-
istics of your scooter, you should
keep the following precautions in
mind.
8NEVER OVERLOAD THE
SCOOTER! Operation of an
overloaded scooter may result
in tire damage, loss of control,
or severe injury. Make sure

during a ride.
8Securely pack the heaviest
items close to the center of the
scooter and distribute the
weight evenly on both sides.
8Adjust the tire air pressure
with regard to the load.
8Check the tire condition and
air pressure before each ride.

Tire inspection
The tires must be checked before
each ride. If the center tread depth
reaches the specified limit, if the tire
has a nail or glass fragments in it, or
if the side wall is cracked, have a
Yamaha dealer replace the tire imme-
diately.NOTE:
The tire tread depth limits may differ
from country to country. Always com-
ply with the local regulations.1. Tire sidewall

EW000079
w8Have a Yamaha dealer replace
excessively worn tires.
Besides being illegal, operat-
ing the scooter with exces-
sively worn tires decreases
riding stability and can lead to
loss of control.
8The replacement of all wheel-
and brake-related parts,
including the tires, should be
left to a Yamaha dealer, who
has the necessary profession-
al knowledge and experience.
Tire information
This scooter is equipped with cast
wheel and tubeless tires.
EW000078
w8The front and rear tires should
be of the same make and
design, otherwise the handling
characteristics of the scooter
cannot be guaranteed.
8After extensive tests, only the
tires listed below have been
approved for this model by
Yamaha Motor Co., Ltd.

Cast wheelsTo maximize the performance, dura-
bility, and safe operation of your
scooter, note the following points
regarding the specified wheels.
8The wheel rims should be
checked for cracks, bends or
warpage before each ride. If any
damage is found, have a
Yamaha dealer replace the
wheel. Do not attempt even the
smallest repair to the wheel. A
deformed or cracked wheel must
be replaced.
8The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced.
An unbalanced wheel can result
in poor performance, adverse
handling characteristics, and a
shortened tire life.
8Ride at moderate speeds after
changing a tire since the tire sur-
face must first be “broken in” for
it to develop its optimal charac-
teristics.
EAU03851
Front and rear brake leversThere should be no free play at the
brake lever ends. If there is free play,
have a Yamaha dealer inspect the
brake system.
EAU00683
w8Have a Yamaha dealer replace
excessively worn tires.
Besides being illegal, operat-
ing the scooter with exces-
sively worn tires decreases
riding stability and can lead to

and brake-related parts,
including the tires, should be
left to a Yamaha dealer, who

9After cleaning
1. Dry the scooter 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
induced discoloring of stainless-
steel exhaust systems can be
removed through polishing.)
3. To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all metal, includ-
ing chrome- and nickel-plated,
surfaces.
4. Use spray oil as a universal
cleaner to remove any remaining
dirt.
5. Touch up minor paint damage
caused by stones, etc.6. Wax all painted surfaces.
7. Let the scooter dry completely
before storing or covering it.
EWA00002
w8Make sure that there is no oil
or wax on the brakes or tires.
If necessary, clean the brake
discs and brake linings with a
regular brake disc cleaner or
acetone, and wash the tires
with warm water and a mild
detergent.
8Before operating the scooter
test its braking performance
and cornering behavior.
ECA00013
cC8Apply spray oil and wax spar-
ingly and make sure to wipe
off any excess.
8Never apply oil or wax to any
rubber and plastic parts, but
treat them with a suitable care
product.
8Avoid using abrasive polish-
ing compounds as they will
wear away the paint.NOTE:
Consult a Yamaha dealer for advice
on what products to use.

95. Lubricate all control cables and
the pivoting points of all levers
and pedals as well as of the
sidestand/centerstand.
6. Check and, if necessary, correct
the tire air pressure, and then lift
the scooter so that both of its
wheels are off the ground.
Alternatively, turn the wheels a
little every month in order to pre-
vent the tires from becoming
degraded in one spot.
7. Cover the muffler outlet with a
plastic bag to prevent moisture
from entering it.8. Remove the battery and fully
charge it. Store it in a cool, dry
place and charge 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 informa-
tion on storing the battery, see
page 6-33.
NOTE:
Make any necessary repairs before
storing the scooter.
