WARNING
PLEASE READ THIS MANUAL CAREFULLY AND COMPLETELY BEFORE OPERATING THIS SCOOTER.
SCOOTERS ARE SINGLE TRACK
VEHICLES. THEIR SAFE USE AND
1
OPERATION ARE DEPENDENT
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 INSTRUC-
TIONS FROM A COMPETENT
SOURCE ON ALL ASPECTS OF
SCOOTER OPERATION.
● OBSERVE THE WARNINGS AND
MAINTENANCE REQUIREMENTS IN THE OWNER’S
MANUAL.
● OBTAIN QUALIFIED TRAINING
IN SAFE AND PROPER RIDING
TECHNIQUES.
● OBTAIN PROFESSIONAL TECH-
NICAL SERVICE AS INDICATED
BY THE OWNER’S MANUAL
AND/OR WHEN MADE NECESSARY BY MECHANICAL CONDITIONS.
EAU10260
Safe riding
● Always make pre-operation
checks. Careful checks may help
prevent an accident.
● This scooter is designed to carry
the operator and passenger.
● The failure of motorists to detect
and recognize scooters in traffic
is the predominating cause of
automobile/scooter accidents.
Many accidents have been caused 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 approaching and passing through
intersections, since intersections 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 inexpe-
rienced operators. In fact, many
operators who have been invol-
1-1
ved in accidents do not even
have a current driver’s license.
• Make sure that you are qualified and that you only lend your
scooter to other qualified operators.
• Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
• We recommend that you practice 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 operator. A typical error made by the
operator is veering wide on a turn
due to EXCESSIVE SPEED or
undercornering (insufficient lean
angle for the speed).
• Always obey the speed limit
and never travel faster than
warranted by road and traffic
conditions.
• Always signal before turning or
changing lanes. Make sure that
other motorists can see you.
SAFETY INFORMATION
t
● 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 footboard
during operation to maintain
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 injuries. The use of a safety helmet is the
single most critical factor in the prevention or reduction of head injuries.
● Always wear an approved hel-
met.
● Wear a face shield or goggles.
Wind in your unprotected eyes
could contribute to an impairment of vision which could delay
seeing a hazard.
● The use of a jacket, substantial
shoes, trousers, gloves, etc., is
effective 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.
● Never touch the engine or
exhaust system during or after
operation. They become very hot
and can cause burns. Always
wear protective clothing that
covers your legs, ankles, and
feet.
● Passengers should also observe
the above precautions.
1-2
Modifications
Modifications made to this scooter
not approved by Yamaha, or the
removal of original equipment, may
render the scooter unsafe for use and
may cause severe personal injury.
Modifications may also make your
scooter illegal to use.
Loading and accessories
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
are some general guidelines to follow
if loading cargo or adding accessories
to your scooter:
1
t
SAFETY INFORMATION
Loading
The total weight of the operator, passenger, accessories and cargo must
1
not exceed the maximum load limit of
189 Kg - 416.75 lb. 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 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 frequently.
● 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 on
this scooter. Since Yamaha cannot
test all other accessories that may be
available, you must personally be responsible for the proper selection, installation 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 “Loading” when mounting accessories.
● Never install accessories or carry
cargo that would impair the performance of your scooter. Carefully inspect the accessory before using it to make sure that it
does not in any way reduce
ground clearance or cornering
clearance, limit suspension travel, steering travel or control operation, or obscure lights or reflectors.
• Accessories fitted to the handlebar or the front fork area can
create instability due to improper weight distribution or
1-3
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 aerodynamic effects. Wind may attempt
to lift the scooter, or the scooter may become unstable in
cross winds. These accessories may also cause instability
when passing or being passed
by large vehicles.
• Certain accessories can displace the operator from his or
her normal riding position. This
improper position limits the freedom of movement of the operator and may limit control ability, therefore, such
accessories are not recommended.
● Use caution when adding electri-
cal accessories. If electrical
accessories exceed the capacity
of the scooter’s electrical system
SAFETY INFORMATION
t
an electric failure could result,
which could cause a dangerous
loss of lights or engine power.
Gasoline and exhaust gas
● GASOLINE IS HIGHLY FLAMMA-
BLE:
• Always turn the engine off
when refueling.
• Take care not to spill any gasoline on the engine or exhaust
system when refueling.
• Never refuel while smoking or
in the vicinity of an open flame.
● Never start the engine or let it run
for any length of time in a closed
area. The exhaust fumes are poisonous and may cause loss of
consciousness and death within
a short time. Always operate your
scooter in an area that has adequate ventilation.
● Always turn the engine off before
leaving the scooter unattended
and remove the key from the
main switch. When parking the
scooter, note the following:
• The engine and exhaust system may be hot, therefore,
park the scooter in a place
where pedestrians or children
are not likely to touch these hot
areas.
• Do not park the scooter on a
slope or soft ground, otherwise
it may fall over.
• Do not park the scooter near a
flammable source (e.g., a kerosene heater, or near an open
flame), otherwise it could catch
fire.
● If you should swallow any gasoli-
ne, inhale a lot of gasoline vapor,
or allow gasoline to get into your
eyes, see your doctor immediately. If any gasoline spills on your
skin or clothing, immediately
wash the affected area with soap
and water and change your clothes.
EAU10371
Further safe-riding points
● Be sure to signal clearly when
making turns.
● Braking can be extremely difficult
on a wet road. Avoid hard braking, because the scooter could
slide. Apply the brakes slowly
1-4
when stopping on a wet surface.
● Slow down as you approach a
corner or turn. Once you have
completed 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 become extremely slippery when wet. Slow down and
cross them with caution. Keep
the scooter upright, otherwise it
could slide out from under you.
● The brake pads could get wet
when you wash the scooter. 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
scooter is unstable.

Immobilizer system
1. Master key
2. Keys
This vehicle is equipped with an
immobilizer system to help prevent
theft by re-registering codes in the
standard keys. This system consists
of the following.
● a code re-registering key (with a
red bow)
● two standard keys (with a black
bow) that can be re-registered
with new codes
● a transponder (which is installed
in the code re-registering key)
● an immobilizer unit
● an ECU
● an immobilizer system indicator
light (See page 3-3.)
The key with the red bow is used to
register codes in each standard key.
Since re-registering is a difficult process, take the vehicle along with all
three keys to a Yamaha dealer to have
them re-registered. Do not use the
key with the red bow for driving. It
should only be used for re-registering
the standard keys. Always use a standard key for driving.
ECA11820
CAUTION:
● DO NOT LOSE THE CODE RE-
REGISTERING KEY! CONTACT
YOUR DEALER IMMEDIATELY IF
IT IS LOST! If the code re-regis-
tering key is lost, registering new
codes in the standard keys is
impossible. The standard keys
can still be used to start the vehi-
cle, however if code re-registe-
ring is required (i.e., if a new
standard key is made or all keys
are lost) the entire immobilizer
system must be replaced. There-
fore, it is highly recommended to
use either standard key and
keep the code re-registering
key in a safe place.
● Do not submerse any key in
water.
● Do not expose any key to
excessively high temperatures.
● Do not place any key close to
magnets (this includes, but not
limited to, products such as
speakers, etc.).
● Do not place heavy items on
any key.
● Do not grind any key or alter its
shape.
● Do not disassemble the plastic
part of any key.
● Do not put two keys of any
immobilizer system on the
same key ring.
● Keep the standard keys as well
as keys of other immobilizer
systems away from this vehicle’s code re-registering key.
● Keep other immobilizer system
keys away from the main
switch as they may cause signal interference.
