CHECKING THE TIRES
The following procedure applies to both of
the tires.
1. Measure:
• tire pressure
Out of specification ® Regulate.
WARNINGWARNING
• The tire pressure should only be
checked and regulated when the tire
temperature equals the ambient air
temperature.
• The tire pressure and the suspension
must be adjusted according to the
total weight (including cargo, rider,
passenger and accessories) and the
anticipated riding speed.
• Operation of an overloaded motorcy-
cle could cause tire damage, an acci-
dent or an injury.
NEVER OVERLOAD THE MOTORCYCLE.
