To ensure maximum performance,
long service, and safe operation, note
the following:
Tire air pressure
Always check and adjust the tire
pressure before operating the motor-
cycle.

Tire inflation pressure should be
checked and adjusted when the
temperature of the tire equals the
ambient air temperature. Tire infla-
tion pressure must be adjusted
according to total weight of cargo,
rider, passenger, and accessories
(fairing, saddlebags, etc. if
approved for this model), and vehi-
cle speed.

and accessories. Maximum load*180 kg

Proper 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.
