●
Do not run engine in poorly venti-
lated or partially enclosed areas
such as barns, garages, or car-
ports.
●
Do not run engine outdoors where
engine exhaust can be drawn into
a building through openings such
as windows and doors.
Loading
Adding accessories or cargo to your
scooter can adversely affect stability
and handling if the weight distribution of
the scooter is changed. To avoid the
possibility of an accident, use extreme
caution when adding cargo or accesso-
ries to your scooter. Use extra care
when riding a scooter that has added
cargo or accessories. Here, along with
the information about accessories be-
low, are some general guidelines to fol-
low if loading cargo to your scooter:
The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit.
Operation of an overloaded vehicle
could cause an accident.When loading within this weight limit,
keep the following in mind:
●
Cargo and accessory weight
should be kept as low and close to
the scooter as possible. Securely
pack your heaviest items as close
to the center of the vehicle as pos-
sible and make sure to distribute
the weight as evenly as possible
on both sides of the scooter to min-
imize imbalance or instability.
●
Shifting weights can create a sud-
den imbalance. Make sure that ac-
cessories and cargo are securely
attached to the scooter before
riding. Check accessory mounts
and cargo restraints frequently.
Properly adjust the suspension
for your load (suspension-ad-
justable models only), and
check the condition and pres-
sure of your tires. Never attach any large or heavy
items to the handlebar, front
fork, or front fender. Such items
can create unstable handling or
a slow steering response.
●
This vehicle is not designed to
pull a trailer or to be attached to
a sidecar.
Genuine Yamaha Accessories
Choosing accessories for your vehicle
is an important decision. Genuine
Yamaha accessories, which are avail-
able only from a Yamaha dealer, have
been designed, tested, and approved
by Yamaha for use on your vehicle.
Many companies with no connection to
Yamaha manufacture parts and acces-
sories or offer other modifications for
Yamaha vehicles. Yamaha is not in a
position to test the products that these
aftermarket companies produce.
Therefore, Yamaha can neither en-
dorse nor recommend the use of ac-
cessories not sold by Yamaha or
modifications not specifically recom-
mended by Yamaha, even if sold and
installed by a Yamaha dealer.
Maximum load:
165 kg (364 lb)

SAFETY INFORMATION

●
Point the front wheel straight
ahead on the trailer or in the truck
bed, and choke it in a rail to pre-
vent movement.
●
Secure the scooter with tie-downs
or suitable straps that are attached
to solid parts of the scooter, such
as the frame or upper front fork tri-
ple clamp (and not, for example, to
rubber-mounted handlebars or
turn signals, or parts that could
break). Choose the location for the
straps carefully so the straps will
not rub against painted surfaces
during transport.
●
The suspension should be com-
pressed somewhat by the tie-
downs, if possible, so that the
scooter will not bounce excessive-
ly during transport.
EAU45371
Further safe-riding points ●
Make sure to signal clearly when
making turns.
Left turn
Right turn
●
Braking can be extremely difficult
on a wet road. Avoid hard braking,
because the scooter could slide.
Apply the brakes slowly when
stopping on a wet surface.
●
Slow down as you approach a cor-
ner or turn. Once you have com-
pleted a turn, accelerate slowly.
●
Be careful when passing parked
cars. A driver might not see you
and open a door in your path.
●
Railroad crossings, streetcar rails,
iron plates on road construction
sites, and manhole covers be-
come extremely slippery when
wet. Slow down and cross them
with caution. Keep the scooter up-
right, otherwise it could slide out
from under you.
●
The brake pads and linings could
get wet when you wash the scoot-
er. After washing the scooter,
check the brakes before riding.
●
Always wear a helmet, gloves,
trousers (tapered around the cuff
and ankle so they do not flap), and
a bright colored jacket.

●
Do not carry too much luggage on
the scooter. An overloaded scoot-
er is unstable. Use a strong cord to
secure any luggage to the carriers.
A loose load will affect the stability
of the scooter and could divert
your attention from the road. (See
page 1-3.)

WARNING
EWA11091
Make sure that the fuel tank cap is
properly closed after filling fuel.
Leaking fuel is a fire hazard.
EAU13221
Fuel Make sure there is sufficient gasoline in
the tank.
WARNING
EWA10881
Gasoline and gasoline vapors are
extremely flammable. To avoid fires
and explosions and to reduce the
risk of injury when refueling, follow
these instructions.1. Before refueling, turn off the en-
gine and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the vi-
cinity of sparks, open flames, or
other sources of ignition such as
the pilot lights of water heaters and
clothes dryers.
2. Do not overfill the fuel tank. When
refueling, be sure to insert the
pump nozzle into the fuel tank filler
hole. Stop filling when the fuel
reaches the bottom of the filler
tube. Because fuel expands when
it heats up, heat from the engine or
the sun can cause fuel to spill out
of the fuel tank.3. Wipe up any spilled fuel immedi-
ately. NOTICE: Immediately wipe
off spilled fuel with a clean, dry,
soft cloth, since fuel may deteri-
orate painted surfaces or plastic
parts.
[ECA10071]
4. Be sure to securely close the fuel
tank cap.
WARNING
EWA15151
Gasoline is poisonous and can
cause injury or death. Handle gaso-
line with care. Never siphon gaso-
line by mouth. If you should swallow
some gasoline or inhale a lot of gas-
oline vapor, or get some gasoline in
your eyes, see your doctor immedi-1. Fuel tank filler tube

Storage compartments NOTICE
ECA17840
Keep the following points in mind
when using the storage compart-
ments.●
Since the storage compart-
ments accumulate heat when
exposed to the sun and/or the
engine heat, do not store any-
thing susceptible to heat, con-
sumables or flammable items
inside them.
●
To avoid humidity from spread-
ing through the storage com-
partments, wrap wet articles in a
plastic bag before storing them
in the compartments.
●
Since the storage compart-
ments may get wet while the ve-
hicle is being washed, wrap any
articles stored in the compart-
ments in a plastic bag.
●
Do not keep anything valuable
or breakable in the storage com-
partments.

EAU22721
Changing the brake fluid Have a Yamaha dealer change the
brake fluid at the intervals specified in
the TIP after the periodic maintenance
and lubrication chart. In addition, have
the oil seals of the brake master cylin-
der and caliper as well as the brake
hose replaced at the intervals listed be-
low or whenever they are damaged or
leaking.●
Oil seals: Replace every two
years.
●
Brake hose: Replace every four

EAU23095
Checking and lubricating the
cables The operation of all control cables and
the condition of the cables should be
checked before each ride, and the ca-
bles and cable ends should be lubricat-
ed if necessary. If a cable is damaged
or does not move smoothly, have a
Yamaha dealer check or replace it.
WARNING! Damage to the outer
housing of cables may result in in-
ternal rusting and cause interfer-
ence with cable movement. Replace
damaged cables as soon as possi-
ble to prevent unsafe conditions.[EWA10711]EAU23114
Checking and lubricating the
throttle grip and cable The operation of the throttle grip should
be checked before each ride. In addi-
tion, the cable should be lubricated by a
Yamaha dealer at the intervals speci-
fied in the periodic maintenance chart.
The throttle cable is equipped with a
rubber cover. Make sure that the cover
is securely installed. Even though the
cover is installed correctly, it does not
completely protect the cable from water
entry. Therefore, use care not to pour
water directly onto the cover or cable
when washing the vehicle. If the cable
or cover becomes dirty, wipe clean with
a moist cloth.
Recommended lubricant:
Yamaha Chain and Cable Lube or
engine oil
