Load Limits & Guidelines
Improperly loading your scooter can
affect its stability and handling. Even if
your scooter is properly loaded, you
should ride at reduced speeds whenever
carrying cargo.

Before Riding
Follow these guidelines whenever you
carry a passenger or cargo:
Check that both tires are properly
inflated, and that pressure in the rear
tire is increased to suit the load
(page 125 ).
To prevent loose items from creating a
hazard, make sure that all cargo is tied
down securely before you ride.
Place cargo weight as low and close to
the center of your scooter as possible.
Balance cargo weight evenly on both
sides.
