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. Make
sure to distribute the weight as
evenly as possible on both sides
of the scooter to minimize imba-
lance or instability.
●Shifting weights can create a
sudden imbalance. Make sure
that accessories and cargo are
securely attached to the scooter
before riding. Check accessory
mounts and cargo restraints fre-
quently.
●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.
Accessories
Genuine Yamaha accessories have
been specifically designed for use onthis scooter. Since Yamaha cannot
test all other accessories that may be
available, you must personally be res-
ponsible for the proper selection, ins-
tallation and use of non-Yamaha
accessories. Use extreme caution
when selecting and installing any
accessories.
Keep the following guidelines in mind,
as well as those provided under “Loa-
ding” when mounting accessories.
●Never install accessories or carry
cargo that would impair the per-
formance of your scooter. Care-
fully inspect the accessory befo-
re using it to make sure that it
does not in any way reduce
ground clearance or cornering
clearance, limit suspension tra-
vel, steering travel or control ope-
ration, or obscure lights or reflec-
tors.
• Accessories fitted to the hand-
lebar or the front fork area can
create instability due to impro-
per weight distribution or
aerodynamic changes. If
accessories are added to the
handlebar or front fork area,they must be as lightweight as
possible and should be kept to
a minimum.
• Bulky or large accessories may
seriously affect the stability of
the scooter due to aerodyna-
mic effects. Wind may attempt
to lift the scooter, or the scoo-
ter may become unstable in
cross winds. These accesso-
ries may also cause instability
when passing or being passed
by large vehicles.
• Certain accessories can dis-
place the operator from his or
her normal riding position. This
improper position limits the fre-
edom of movement of the ope-
rator and may limit control abi-
lity, therefore, such
accessories are not recom-
mended.
●Use caution when adding electri-
cal accessories. If electrical
accessories exceed the capacity
of the scooter’s electrical system
an electric failure could result,
which could cause a dangerous
loss of lights or engine power.

EAU11180
Oil level warning light “z”
This warning light comes on when the
key is in the “h” position or when the
oil level in the 2-stroke engine oil tank
is low during operation. If the warning
light comes on during operation, stop
immediately and fill the oil tank with
Yamalube 2 or equivalent 2-stroke
engine oil of either JASO grade “FC”
or ISO grades “EG-C” or “EG-D”. The
warning light should go off after the 2-
stroke engine oil tank has been refi-
lled.
NOTE:
If the warning light does not come on
when the key is in the “h” position or
does not go off after the 2-stroke
engine oil tank has been refilled, have
a Yamaha dealer check the electrical
circuit.

CAUTION:
Do not operate the vehicle until you
know that the engine oil level is suf-
ficient.

EAU15593
The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpec-
tedly, even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid lea-
kage or loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a tho-
rough visual inspection, to check the following points before each ride.
NOTE:
Pre-operation checks should be made each time the vehicle is used. Such an inspection can be accomplished in a very
short time; and the added safety it assures is more than worth the time involved.

WARNING
If any item in the Pre-operation check list is not working properly, have it inspected and repaired before opera-
ting the vehicle.

Braking
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually
increasing the pressure.

WARNING
●Avoid braking hard or suddenly
(especially when leaning over
to one side), otherwise the sco-
oter may skid or overturn.
●Railroad crossings, streetcar
rails, iron plates on road cons-
truction sites, and manhole
covers become extremely slip-
pery when wet. Therefore, slow
down when approaching suchareas 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 bra-
king downhill can be very diffi-
cult.
EAU16820
Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the follo-
wing tips to reduce fuel consumption:
●Avoid high engine speeds during
acceleration.
●Avoid high engine speeds with no
load on the engine.
●Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at
traffic lights or at railroad cros-
sings).

Matte color cautionECA15192
CAUTION:
Some models are equipped with
matte colored finished parts. Be
sure to consult a Yamaha dealer for
advice on what products to use
before cleaning the vehicle.Using a
brush, harsh chemical products or
cleaning compounds when clea-
ning these parts will scratch or
damage their surface. Wax also
should not be applied to any matte
colored finished parts.
EAU26091
Care
While the open design of a scooter
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
unnoticed on a car, however, it
detracts from the overall appearance
of a scooter. Frequent and proper
care does not only comply with the
terms of the warranty, but it will also
keep your scooter looking good,
extend its life and optimize its perfor-
mance.
Before cleaning
1. 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, inclu-
ding the spark plug cap, are
tightly installed.
3. Remove extremely stubborn dirt,
like oil burnt onto the crankcase,
with a degreasing agent and a
brush, but never apply such pro-ducts onto seals, gaskets and
wheel axles. Always rinse the dirt
and degreaser off with water.
Cleaning
ECA10781
CAUTION:
●Avoid using strong acidic whe-
el cleaners, especially on spo-
ked wheels. If such products
are used on hard-to-remove
dirt, do not leave the cleaner on
the affected area any longer
than instructed. Also, tho-
roughly rinse the area off with
water, immediately dry it, and
then apply a corrosion protec-
tion spray.
●Improper cleaning can damage
plastic parts such as cowlings,
panels, windshields, headlight
lenses, meter lenses, etc. Use
only a soft, clean cloth or spon-
ge with mild detergent and
water to clean plastic.
●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
