TiresTiresTo maximize the performance, dura-
bility, and safe operation of your
scooter, 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.
EW000082
w8The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the tempera-
ture of the tires equals the
ambient temperature).
8The tire air pressure must be
adjusted in accordance with
the riding speed and with the
total weight of rider, passen-
ger, cargo, and accessories
approved for this model.
EWA00040
wBecause loading has an enormous
impact on the handling, braking,
performance and safety character-
istics of your scooter, you should
keep the following precautions in
mind.
8NEVER OVERLOAD THE
SCOOTER! Operation of an
overloaded scooter may result
in tire damage, loss of control,
or severe injury. Make sure
that the total weight of rider,
passenger, cargo, and acces-sories does not exceed the
specified maximum load for
the vehicle.
8Do not carry along loosely
packed items, which can shift
during a ride.
8Securely pack the heaviest
items close to the center of the
scooter and distribute the
weight evenly on both sides.
8Adjust the tire air pressure
with regard to the load.
8Check the tire condition and
air pressure before each ride.

cCBe sure to use motor oils that do not contain anti-friction
modifiers. Passenger car motor oils (often labeled “ENERGY
CONSERVING
II”) contain anti-friction additives which will
cause clutch and/or starter clutch slippage, resulting in
reduced component life and poor engine performance.
