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 ac-
cessories) and the anticipated riding
speed.

Operation of an overloaded motorcycle
could cause tire damage, an accident or an
injury.

CHECKING AND CHARGING THE BATTERY
Batteries generate explosive hydrogen gas
and contain electrolyte which is made of poi-
sonous and highly caustic sulfuric acid.
Therefore, always follow these preventive
measures:

Wear protective eye gear when handling or
working near batteries.

Charge batteries in a well-ventilated area.

Keep batteries away from fire, sparks or
open flames (e.g., welding equipment,

Make sure that the current
is higher than the standard
charging current written on
the battery.
By turning the charging
voltage adjust dial, set the
