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 checks
each time you use the vehicle tomake 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.
TIP
Although this scooter is designed to
carry a passenger, always comply
with the local regulations.
●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, sinceintersections 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-

●Do not run engine indoors. Even
if you try to ventilate engine
exhaust with fans or open win-
dows and doors, carbon monoxi-
de can rapidly reach dangerous
levels.
●Do not run engine in poorly venti-
lated or partially enclosed areas
such as barns, garages, or car-
ports.
●Do not run engine outdoors whe-
re 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 accessories to your scooter. Use
extra care when riding a scooter that
has added cargo or accessories.
Here, along with the information
about accessories below, are some
general guidelines to follow 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. Secu-
rely pack your heaviest items as
close to the center of the vehicle
as possible and make sure to dis-
tribute the weight as evenly as
possible on both sides of the
scooter to minimize imbalance 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.
●Properly adjust the suspension
for your load (suspension-adjus-
table models only), and check the
condition and pressure 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 avai-
lable 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
accessories or offer other modifica-
tions for Yamaha vehicles. Yamaha is
not in a position to test the products
that these aftermarket companies
produce. Therefore, Yamaha can neit-
her endorse nor recommend the use
of accessories not sold by Yamaha or

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 reduceground 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 accesso-
ries are 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
6-11 for tire specifications and more
information on replacing your tires.

sWARNING
●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

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).

sWARNING
●Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the
vehicle with excessively worn
tires decreases riding stability
and can lead to loss of control.
●The replacement of all wheel
and brake related parts, inclu-
ding the tires, should be left to
a Yamaha dealer, who has the
necessary professional know-
ledge and experience.

Cast wheels
To maximize the performance, durabi-
lity, and safe operation of your vehi-
cle, note the following points regar-
ding the specified wheels.
●The wheel rims should be chec-
ked 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 crac-
ked 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
handling characteristics, and a
shortened tire life.
●Ride at moderate speeds after
changing a tire since the tire sur-
face must first be “broken in” for
it to develop its optimal characte-
ristics.

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
NOTICE
●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
