exposed to the sun, do not store
anything susceptible to heat
inside it.
•To avoid humidity from
spreading through the storage
compartment, wrap wet articles
in a plastic bag before storing
them in the compartment.
•Since the storage compartment
may get wet while the scooter
is being washed, wrap any arti-
cles stored in the compartment
in a plastic bag.
•Do not keep anything valuable
or breakable in the storage
compartment.To store a helmet in the storage
compartment, place the helmet upside-
down with the front facing forward.
NOTE :
•Some helmets cannot be stored

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