GENERAL TIGHTENING TORQUE
SPECIFICATIONS
This chart specifies tightening torques for stan-
dard fasteners with a standard ISO thread
pitch. Tightening torque specifications for spe-
cial components or assemblies are provided
for each chapter of this manual. To avoid war-
page, tighten multi-fastener assemblies in a
crisscross pattern and progressive stages until
the specified tightening torque is reached. Un-
less otherwise specified, tightening torque
specifications require clean, dry threads. Com-
ponents should be at room temperature.

WARNING
EAS00162
CHECKING THE TIRES
The following procedure applies to both of the
tires.
1. Check:

tire pressure
Out of specification
Regulate.

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.
NEVER OVERLOAD THE MOTORCYCLE.

3. Adjust:

front wheel static balance
a. Install a balancing weight
1 onto the rim ex-
actly opposite the heavy spot “X”.
Start with the lightest weight.
b. Turn the front wheel 90 so that the heavy
spot is positioned as shown.
c. If the heavy spot does not stay in that posi-
tion, install a heavier weight.
d. Repeat steps (b) and (c) until the front wheel
is balanced.
4. Check:

front wheel static balance
a. Turn the front wheel and make sure it stays at
each position shown.
b. If the front wheel does not remain stationary
at all of the positions, rebalance it.
