wProper loading of your motorcycle
is important for several character-
istics of your motorcycle, such as
handling, braking, performance
and safety. Do not carry loosely
packed items that can shift.
Securely pack your heaviest items
close to the center of the motorcy-
cle, and distribute the weight even-
ly from side to side. Properly
adjust the suspension for your
load, and check the condition and
pressure of your tires. NEVER
OVERLOAD YOUR MOTORCYCLE.
Make sure the total weight of the
cargo, rider, passenger, and
accessories (fairing, saddlebags,
etc. if approved for this model)
does not exceed the maximum
load of the motorcycle. Operation
of an overloaded motorcycle could
cause tire damage, an accident, or
even injury.
