SAFETY INFORMATION
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 toYamaha 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-
namic 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

EAU50332
Traveling distance TIPThe 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, 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).

compared with riding in the stan-


Because of the battery character,
the riding distance might be re-
duced according to the ambient
temperature due to changes of the
battery temperature.

The distance that can be traveled
becomes 5–10% shorter when the
vehicle load is increased 10 kg.
EAU50342
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 bat-
tery life, handle as follows:
Choose a cool place with no direct
sunlight when charging the bat-
tery.

Do not store the battery with a
charge less than 20% (below the
last segment of the battery level in-
dicator) 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 until2–3 segments of the battery
charge indicator are shown.
NOTICE
ECA17071
If the battery is discharged until the
battery is depleted, recharging will
not be possible and the battery willnot be usable.

progress status is shown.
TIP
The battery may be above the
maximum 50 C suitable for charg-
ing immediately after riding. In this
case, the charger enters a waiting
mode and “HEAT” flashes until the
battery and battery charger reach
the specified temperature. Charg-
ing then starts automatically.

If ambient temperature is below
–5 C, “COOL” flashes and the
vehicle enters a waiting mode un-
til the battery and battery charger
reach the specified temperature.
Charging then starts automatical-
ly.

If the battery is already fully
charged when the charging plug is
plugged in, the display will show
the fully charged status for a few
minutes and then go off. The bat-
tery charger will not charge thebattery further.
