SAFETY INFORMATION
1tice 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).
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 is im-
portant for proper control. The op-
erator 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 acceler-
ator 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 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 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 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, acces-
sories and cargo must not exceed the
maximum load limit. Operation of an
overloaded vehicle could cause an
accident.

SAFETY INFORMATION
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 suspensionfor 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-
ucts or having other modifications per-
formed 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 “Load-
ing” when mounting accessories.

Never install accessories or carry
cargo that would impair the perfor-
mance 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 sus-
pension travel, steering travel or
control operation, or obscure lights
or reflectors.
Accessories fitted to the handle-
bar or the front fork area can
create instability due to improper
weight distribution or aerody-

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, de-
creased battery performance, and lowtire 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.
TIPThe maximum slope ascending capac-
ity is a gradient of approximately 16%(about 9 degrees).
Because of the battery character,
the riding distance might be re-

Tires Tires are the only contact between the
vehicle and the road. Safety in all con-
ditions of riding depends on a relatively
small area of road contact. Therefore, it
is essential to maintain the tires in good
condition at all times and replace them
at the appropriate time with the speci-
fied tires.
Tire air pressure
The tire air pressure should be checked
and, if necessary, adjusted before each
ride.

der to extend the battery life, it is
recommended to charge the
battery until the battery level in-
dicator reaches a maximum of
2–3 segments. A lower or higher
charge is not recommended.

Make sure that the amount of
charge remaining in the battery
does not fall below 20% (less
than the last segment of the bat-
tery level indicator). If stored un-
der this condition for a long
period of time, the battery can
be damaged and may need to be
replaced depending on how low
the capacity is.

Once the battery is completely
depleted, it cannot be re-
charged.

After long-term storage, be sure
to recharge the battery before
using the vehicle. (It may takelonger to charge than usual.)
Before storing your scooter for several
months: 1. Follow all the instructions in the “Care” section of this chapter.
2. Lubricate all control cables and the pivoting points of all levers as well
as the centerstand.
3. Check and, if necessary, correct the tire air pressure, and then lift
the scooter so that both of its
wheels are off the ground. Alterna-
tively, turn the wheels a little every
month in order to prevent the tires
from becoming degraded in one
spot.
TIPMake any necessary repairs beforestoring the scooter.
