Be a Responsible Owner
As the vehicle’s owner, you are responsible for the safe and proper operation
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 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 Owner’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 necessary by mechanical conditions.
Never operate a scooter without
proper training or instruction. Take
a training course. Beginners
should receive training from a certified instructor. Contact an authorized scooter dealer to find out
about the training courses nearest
you.
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 5-1
for a list of pre-operation checks.
This scooter is designed to carry
the operator only. No passengers.
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.
1-1
• Use extra caution when you are
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.
• Never maintain a scooter without proper knowledge. Contact
an authorized scooter dealer to
inform you on basic scooter
maintenance. Certain maintenance can only be carried out by
certified staff.
Many accidents involve inexperi-
enced operators. In fact, many operators who have been involved 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 prac-
1
SAFETY INFORMATION
tice riding your scooter where
there is no traffic until you have
become thoroughly familiar with
1
the scooter and all of its controls.
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 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.
The posture of the operator is im-
portant for proper control. The operator should keep both hands on
the handlebar and both feet on the
operator footrests during operation
to maintain control of the scooter.
Do not place magnets or objects
with a strong magnetic force near
the accelerator grip. In addition, do
not place objects susceptible to
magnetic forces (i.e., credit cards,
watches, etc.) close to the accelerator grip.
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.
Avoid submerged roads
Do not ride on flooded roads. Water
could cause power unit failure, electric
leakage, and/or short-circuiting.
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 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 effective in preventing or reducing
abrasions or lacerations.
1-2
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 power unit become hot
during or after operation and can
cause burns.
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, accessories and cargo must not exceed the
maximum load limit. Operation of an
overloaded vehicle could cause an
accident.
SAFETY INFORMATION
Maximum load:
87 kg (192 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. Securely
pack your heaviest items as close
to the center of the vehicle as possible and 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 sud-
den imbalance. Make sure that accessories 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-adjustable 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 available 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 modifications for
Yamaha vehicles. Yamaha is not in a
position to test the products that these
aftermarket companies produce.
Therefore, Yamaha can neither endorse nor recommend the use of accessories not sold by Yamaha or
modifications not specifically recommended by Yamaha, even if sold and
installed by a Yamaha dealer.
Aftermarket Parts, Accessories,
and Modifications
While you may find aftermarket products similar in design and quality to
1-3
genuine Yamaha accessories, recognize that some aftermarket accessories
or modifications are not suitable because of potential safety hazards to you
or others. Installing aftermarket products or having other modifications 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 “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 aerody-
1
SAFETY INFORMATION
namic changes. If accessories
are added to the handlebar or
front fork area, they must be as
1
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, an
electric failure could result, which
could cause a dangerous loss of
lights or motor power.
Aftermarket Tires and Rims
The tires and rims that came with your
scooter were designed to match the
performance capabilities and to provide
the best combination of handling, braking, and comfort. Other tires, rims, sizes, and combinations may not be
appropriate. Refer to page 8-5 for tire
specifications and more information on
replacing your tires.
Transporting the Scooter
Be sure to observe following instructions before transporting the scooter in
another vehicle.
Remove all loose items from the
scooter.
Point the front wheel straight
ahead on the trailer or in the truck
bed, and choke it in a rail to prevent movement.
Secure the scooter with tie-downs
or suitable straps that are attached
to solid parts of the scooter, such
as the frame or upper front fork triple clamp (and not, for example, to
rubber-mounted handlebars or
1-4
turn signals, or parts that could
break). Choose the location for the
straps carefully so the straps will
not rub against painted surfaces
during transport.
The suspension should be com-
pressed somewhat by the
tie-downs, if possible, so that the
scooter will not bounce excessively during transport.
SAFETY INFORMATION
EAUT2031
Further safe-riding points
Make 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 when
stopping on a wet surface.
Slow down as you approach a cor-
ner 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 lining 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.

EAU50823
Charging the battery safely
Do not charge the battery in areas
potentially exposed to rain or water. This could cause an electric
shock or short circuit.
Be sure to plug the charging plug
only directly to a grounded electrical outlet with residual-current device (RCD) protection to charge
the battery. If incorrectly grounded,
this could cause an electric shock
or short circuit.
If the vehicle is damaged due to
overturning or accident, do not
plug in the charging plug to an outlet. This could cause an electric
shock or short circuit. Have your
vehicle checked by a Yamaha
1
SAFETY INFORMATION
dealer as soon as possible.
If the charging cord or charging
plug is damaged, do not plug in to
1
an outlet. This could cause an
electric shock or short circuit. Have
your vehicle checked by a
Yamaha dealer as soon as possible.

Traveling distance
The distance that can be traveled on a
single charge varies according to the
riding and road conditions.
These conditions include the number of
starts and stops, vehicle load, the
steepness of slopes, road conditions,
wind direction and velocity, ambient
temperature, charging status, decreased battery performance, and low
tire air pressure.
Distance traveled on a single
charge
The data in the following chart was
measured at Yamaha Motor Co., Ltd. It
was measured when traveling with a
new battery at an ambient temperature
and vehicle load (total weight of rider
and luggage) as shown below on a dry
road surface in the absence of wind.
The maximum slope ascending capacity is a gradient of approximately 16%
(about 9 degrees).
Because of the battery character,
the riding distance might be re-

Effective use of the battery
If the battery is left nearly fully charged
(4–5 segments shown on the battery
charge indicator) and exposed to high
temperature for an extended period, it
will rapidly deplete. To extend the battery life, handle as follows:
Choose a cool place with no direct
sunlight when charging the battery.
Do not store the battery with a
charge less than 20% (below the
last segment of the battery level indicator) for an extended period of
time.
Choose a cool and well-ventilated
place without direct sunlight for
storing the vehicle.
When not used for a long period of
time, charge the battery until the
2–3 segments of the battery
charge indicator are shown and
then store the vehicle in a cool
place (optimum temperature 15 C
– 25 C). Check the battery level
while the vehicle is in storage. If
the battery level drops to the last
segment, recharge the battery until
3-2
2–3 segments of the battery
charge indicator are shown.
