Be a Responsible Owner
As the vehicle’s owner, you are res-
ponsible for the safe and proper ope-
ration of your scooter.
Scooters are single-track vehicles.
Their safe use and operation are
dependent upon the use of proper
riding techniques as well as the
expertise of the operator. Every ope-
rator should know the following requi-
rements before riding this scooter.
He or she should:
Obtain thorough instructions
from a competent source on all
aspects of scooter operation.
Observe the warnings and main-
tenance requirements in this
Owner’s Manual.
Obtain qualified training in safe
and proper riding techniques.
Obtain professional technical
service as indicated in this
Owner’s Manual and/or when
made necessary by mechanical
conditions.
Safe Riding
Perform the pre-operation checkseach time you use the vehicle to
make sure it is in safe operating con-
dition. Failure to inspect or maintain
the vehicle properly increases the
possibility of an accident or equip-
ment damage. See page 4-1 for a list
of pre-operation checks.
This scooter is designed to carry
the operator and a passenger.
The failure of motorists to detect
and recognize scooters in traffic
is the predominating cause of
automobile/scooter accidents.
Many accidents have been cau-
sed by an automobile driver who
did not see the scooter. Making
yourself conspicuous appears to
be very effective in reducing the
chance of this type of accident.
Therefore:
• Wear a brightly colored jacket.
• Use extra caution when you
are approaching and passing
through intersections, since
intersections are the most
likely places for scooter acci-
dents to occur.• Ride where other motorists can
see you. Avoid riding in anot-
her motorist’s blind spot.
Many accidents involve inexpe-
rienced operators. In fact, many
operators who have been invol-
ved in accidents do not even
have a current driver’s license.
• Make sure that you are quali-
fied and that you only lend your
scooter to other qualified ope-
rators.
• Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
• We recommend that you prac-
tice riding your scooter where
there is no traffic until you have
become thoroughly familiar
with the scooter and all of its
controls.
Many accidents have been cau-
sed by error of the scooter ope-
rator. A typical error made by the
operator is veering wide on a turn
due to excessive speed or under-
cornering (insufficient lean angle
for the speed).

Aftermarket Parts, Accessories,
and Modifications
While you may find aftermarket pro-
ducts similar in design and quality to
genuine Yamaha accessories, recog-
nize that some aftermarket accesso-
ries or modifications are not suitable
because of potential safety hazards to
you or others. Installing aftermarket
products or having other modifica-
tions performed to your vehicle that
change any of the vehicle’s design or
operation characteristics can put you
and others at greater risk of serious
injury or death. You are responsible
for injuries related to changes in the
vehicle.
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 displa-
ce 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 accessoriesare not recommended.
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.
Aftermarket Tires and Rims
The tires and rims that came with your
scooter were designed to match the
performance capabilities and to pro-
vide the best combination of hand-
ling, braking, and comfort. Other tires,
rims, sizes, and combinations may
not be appropriate. Refer to page
6-18 for tire specifications and more
information on replacing your tires.

The vehicle must not be ridden with
the sidestand down, or if the sides-
tand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control. Yama-
ha’s ignition circuit cut-off system
has been designed to assist the
operator in fulfilling the responsibi-
lity of raising the sidestand before
starting off. Therefore, check this
system regularly as described
below and have a Yamaha dealer
repair it if it does not function pro-
perly.
EAU45051
Ignition circuit cut-off
system
The ignition circuit cut-off system
(comprising the sidestand switch and
brake light switches) has the following
functions.
It prevents starting when the
sidestand is up, but neither brake
is applied.
It prevents starting when either
brake is applied, but the sides-
tand is still down.
It cuts the running engine when
the sidestand is moved down.
Periodically check the operation of
the ignition circuit cut-off system
according to the following procedure.

BrakingEWA10300
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 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 bra-
king downhill can be very diffi-
cult.
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually
increasing the pressure.Front

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
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 pro-
ducts or cleaning compounds
when cleaning these parts will
scratch or damage their surface.
Wax also should not be applied to
any matte colored finished parts.
EAU26094
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 abrush, but never apply such pro-
ducts onto seals, gaskets and
wheel axles. Always rinse the dirt
and degreaser off with water.
Cleaning
ECA10783
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.) and
the mufflers. Use only a soft,
clean cloth or sponge with
water to clean plastic. Howe-
ver, if the plastic parts cannot
be thoroughly cleaned with
water, diluted mild detergent
