SAFETY INFORMATION

Be a Responsible Owner
As the vehicle’s owner, you are respon-
sible for the safe and proper operation
of your scooter.
Scooters are single-track vehicles.
Their safe use and operation are de-
pendent upon the use of proper riding
techniques as well as the expertise of
the operator. Every operator should
know the following requirements 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 mainte-
nance requirements in this Own-
er’s Manual.

Obtain qualified training in safe
and proper riding techniques.

Obtain professional technical ser-
vice as indicated in this Owner’s
Manual and/or when made neces-
sary by mechanical conditions.
Safe Riding
Perform the pre-operation checks each
time you use the vehicle to make sure it
is in safe operating condition. Failure to
inspect or maintain the vehicle properly
increases the possibility of an accident
or equipment 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 auto-
mobile/scooter accidents. Many
accidents have been caused by an
automobile driver who did not see
the scooter. Making yourself con-
spicuous appears to be very effec-
tive 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 in-
tersections are the most likely
places for scooter accidents to
occur.

Ride where other motorists can
see you. Avoid riding in another
motorist’s blind spot.

Many accidents involve inexperi-
enced operators. In fact, many op-
erators who have been involved in
accidents do not even have a cur-
rent driver’s license.

Make sure that you are qualified
and that you only lend your
scooter to other qualified opera-
tors.

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 con-
trols.

Many accidents have been caused
by error of the scooter operator. A
typical error made by the operator
is veering wide on a turn due to ex-
cessive speed or undercornering
(insufficient lean angle for the
speed).

SAFETY INFORMATION

Always obey the speed limit and
never travel faster than warrant-
ed by road and traffic conditions.

Always signal before turning or
changing lanes. Make sure that
other motorists can see you.

The posture of the operator and
passenger is important for proper
control.

The operator should keep both
hands on the handlebar and
both feet on the operator foot-
rests during operation to main-
tain control of the scooter.

The passenger should always
hold onto the operator, the seat
strap or grab bar, if equipped,
with both hands and keep both
feet on the passenger footrests.
Never carry a passenger unless
he or she can firmly place both
feet on the passenger footrests.

Never ride under the influence of
alcohol or other drugs.

This scooter is designed for
on-road use only. It is not suitable
for off-road use.
Protective apparel
The majority of fatalities from scooter
accidents are the result of head inju-
ries. The use of a safety helmet is the
single most critical factor in the preven-
tion or reduction of head injuries.

Always wear an approved helmet.

Wear a face shield or goggles.
Wind in your unprotected eyes
could contribute to an impairment
of vision that could delay seeing a
hazard.

The use of a jacket, substantial
shoes, trousers, gloves, etc., is ef-
fective in preventing or reducing
abrasions or lacerations.

Never wear loose-fitting clothes,
otherwise they could catch on the
control levers or wheels and cause
injury or an accident.

Always wear protective clothing
that covers your legs, ankles, and
feet. The engine or exhaust sys-
tem become very hot during or af-
ter operation and can cause burns.

A passenger should also observe
the above precautions.
Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon
monoxide, a deadly gas. Breathing car-
bon monoxide can cause headaches,
dizziness, drowsiness, nausea, confu-
sion, and eventually death.
Carbon Monoxide is a colorless, odor-
less, tasteless gas which may be
present even if you do not see or smell
any engine exhaust. Deadly levels of
carbon monoxide can collect rapidly
and you can quickly be overcome and
unable to save yourself. Also, deadly
levels of carbon monoxide can linger
for hours or days in enclosed or poorly
ventilated areas. If you experience any
symptoms of carbon monoxide poison-
ing, leave the area immediately, get
fresh air, and SEEK MEDICAL TREAT-
MENT.

Do not run engine indoors. Even if
you try to ventilate engine exhaust
with fans or open windows and
doors, carbon monoxide can rap-
idly reach dangerous levels.

Do not run engine in poorly ventilat-
ed or partially enclosed areas such
as barns, garages, or carports.

SAFETY INFORMATION

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.
Aftermarket Parts, Accessories,
and Modifications
While you may find aftermarket prod-
ucts similar in design and quality to
genuine Yamaha accessories, recog-
nize that some aftermarket accessories
or modifications are not suitable be-
cause of potential safety hazards to you
or others. Installing aftermarket prod-
