Q SAFETY INFORMATIONLoading
The total weight of the operator, passen-
ger, accessories and cargo must not ex-
ceed the maximum load limit of 170 kg
(374 lb). When loading within this weight
limit, keep the following in mind:
8Cargo 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.
8Shifting 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.
8Never attach any large or heavy
items to the handlebar, front fork,
or front fender. Such items can cre-
ate 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 avail-
able, you must personally be responsible
for the proper selection, installation and
use of non-Yamaha accessories. Use
extreme caution when selecting and in-
stalling any accessories.
Keep the following guidelines in mind,
as well as those provided under “Load-
ing” when mounting accessories.
8Never install accessories or carry
cargo that would impair the perfor-
mance of your scooter. Carefully
inspect the accessory before us-
ing it to make sure that it does not
in any way reduce ground clear-
ance or cornering clearance, limit
suspension travel, steering travel
or control operation, or obscure
lights or reflectors.
9Accessories fitted to the
handlebar or the front fork area
can create instability due to
improper weight distribution or
aerodynamic changes. Ifaccessories are added to the
handlebar or front fork area,
they must be as lightweight as
possible and should be kept to
a minimum.
9Bulky 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.
9Certain 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 recom-
mended.
8Use caution when adding electrical
accessories. If electrical accesso-
ries exceed the capacity of the
scooter’s electrical system an elec-

TiresTo maximize the performance, durabil-
ity, and safe operation of your vehicle,
note the following points regarding the
specified tires.
Tire air pressure
The tire air pressure should be checked
and, if necessary, adjusted before each
ride.
EWA10500
w8 88 8
8The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperature
of the tires equals the ambient
temperature).
8 88 8
8The tire air pressure must be
adjusted in accordance with the
riding speed and with the total
weight of rider, passenger, cargo,
and accessories approved for this
model.
Tire air pressure (measured on cold
tires):
0~90 kg (0~198 lb):
Front:
175 kPa (26 psi) (1.75 kgf/cm
2)
Rear:
200 kPa (29 psi) (2.0 kgf/cm2)
90~170 kg (198~419 lb) to maxi-
mum load:
Front:
200 kPa (29 psi) (2.0 kgf/cm2)
Rear:
225 kPa (33 psi) (2.25 kgf/cm2)
Maximum load*:
170 kg (374 lb)
* Total weight of rider, passenger,
cargo and accessories

wBecause loading has an enormous
impact on the handling, braking, per-
formance and safety characteristics
of your vehicle, you should keep the
following precautions in mind.
8 88 8
8NEVER OVERLOAD THE VE-
HICLE! Operation of an over-
loaded motorcycle may result in
tire damage, loss of control, orsevere injury. Make sure that the
total weight of rider, passenger,
cargo, and accessories does not
exceed the specified maximum
load for the vehicle.
8 88 8
8Do not carry along loosely
packed items, which can shift
during a ride.
Securely pack the heaviest items
close to the center of the vehicle
and distribute the weight evenly
on both sides.
8 88 8
8Adjust the tire air pressure with
regard to the load.
Check the tire condition and air
pressure before each ride.
