Braking
WARNING
EWA10300
Avoid braking hard or suddenly
(especially when leaning over to
one side), otherwise the scooter
may skid or overturn.
Railroad crossings, streetcar
rails, iron plates on road con-
struction sites, and manhole
covers become extremely slip-
pery when wet. Therefore, slow
down when approaching such
areas and cross them with cau-
tion.
Keep in mind that braking on a
wet road is much more difficult.
Ride slowly down a hill, as brak-
ing downhill can be very diffi-cult.
1. Close the accelerator grip com-
pletely.
2. Apply both front and rear brakes
simultaneously while gradually in-
creasing the pressure.Front

ground, otherwise the vehicle mayoverturn.TIP
If the vehicle is parked in an ex-
tremely hot or cold place, the tem-
perature protection function may
be activated when the key is
turned to “ON”. If this is activated,
“HEAT” or “COOL” flashes on the
tripmeter/odometer display. (See
page 4-4 “Temperature warning
display” for more information about
the temperature protection func-
tion.)
It is recommended to lock the se-
curity lock when parking. (See

PERIODIC MAINTENANCE AND ADJUSTMENT
EAU50130
Periodic inspection, adjustment, and lu-
brication will keep your vehicle in the
safest and most efficient condition pos-
sible. Safety is an obligation of the vehi-
cle owner/operator. The most important
points of vehicle inspection, adjust-
ment, and lubrication are explained on
the following pages.
The intervals given in the periodic
maintenance charts should be simply
considered as a general guide under
normal riding conditions. However, de-
pending on the weather, terrain, geo-
graphical location, and individual use,
the maintenance intervals may need to
be shortened.
WARNING
EWA10321
Failure to properly maintain the ve-
hicle or performing maintenance ac-
tivities incorrectly may increase
your risk of injury or death during
service or while using the vehicle. If
you are not familiar with vehicle ser-
vice, have a Yamaha dealer performservice.
WARNING
EWA15840
Turn the key to “OFF” when per-
forming maintenance unless other-
wise specified. A running motor has
moving parts that can catch on body
parts or clothing and electrical partsthat can cause shocks or fires.
WARNING
EWA15830
This scooter is designed for use onpaved roads only.
WARNING
EWA15460
Brake discs, calipers, drums, and
linings can become very hot during
use. To avoid possible burns, let
brake components cool beforetouching them.

sounds Check the motor for irregular sounds.TIPThe motor cannot be revved beyond a
certain motor speed by turning the ac-
celerator grip when the vehicle is on thecenterstand.
EAU50154
Checking the accelerator grip Before checking the accelerator grip,
check the following points.
Make sure that the key is in the
“OFF” position. Turn the accelera-
tor grip slowly and check that it
moves smoothly, and returns
smoothly when released.
Check for any signs of deteriora-
tion or damage around the accel-
erator grip. Also check the
accelerator grip holder mounting
bolts for tightness.
When washing the vehicle, avoid
spraying the area around the ac-
celerator grip with water. If the
area around the accelerator grip is
particularly dirty, use a well-wrung
damp cloth to clean.
WARNING
EWA15671
If a problem is found in accelerator
grip operation, do not operate the
vehicle. Have the vehicle inspected
by a Yamaha dealer. Continuing to
use the vehicle with a problem in-
creases the possibility of an acci-dent or equipment damage.
1. Squeeze the rear brake lever with
your left hand.
2. Turn the key to “ON”.
3. Cancel the standby mode by
pressing one of the control but-
tons. (See page 4-3.)
4. Make sure that the operating sta-
tus indicator “RUN” is displayed,
and that the vehicle is in the riding
mode. (See page 7-1 for more in-
formation about “Preparations for
starting off” and “Starting off”.)
5. Check that the accelerator grip
and motor operate smoothly when
the vehicle is accelerated by grad-
ually turning the accelerator grip
while riding the vehicle. If there is a
problem, have a Yamaha dealer
check the vehicle.

specified tires.
Tire air pressure
The tire air pressure should be checked
and, if necessary, adjusted before each
ride.
WARNING
EWA10511
Never overload your vehicle. Opera-
tion of an overloaded vehicle couldcause an accident.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 sidewall is
cracked, have a Yamaha dealer re-
place the tire immediately.
TIPThe tire tread depth limits may differ
from country to country. Always complywith the local regulations.Tire information
This vehicle is equipped with cast
wheels and tube tires.
After extensive tests, only the tires list-
ed below have been approved for this
model by Yamaha Motor Co., Ltd.
WARNING
EWA10471
Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the vehi-
cle with excessively worn tires
decreases riding stability and
can lead to loss of control.
The replacement of all wheel
and brake-related parts, includ-
ing the tires, should be left to a
Yamaha dealer, who has the

Cast wheels
WARNING
EWA10610
The wheels on this model are not de-
signed for use with tubeless tires.
Do not attempt to use tubeless tireson this model.
To maximize the performance, durabil-
ity, and safe operation of your vehicle,
note the following points regarding the
specified wheels.
The wheel rims should be checked
for cracks, bends, warpage or
damage 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.
The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in
poor performance, adverse han-
dling characteristics, and a short-
ened tire life.
