sure that it rests on the flange correctly.
• Fit the most suitable pin (depending on the
wheel's central hole) onto the shaft after
removing the threaded hub.
• Mount the wheel after selecting the centring
cones (one for each side of the wheel), tighten
with the appropriate ring nut using the spacers
necessary for coupling the securing cones to
the threaded part of the shaft.
IMPORTANT: the wheel must be fixed to the
flange so as to avoid any movement of the two
during the spin or braking phases.
- Select the Balancing Programme
icon then, pressing the Kis knob or the enter
button, set the MOTORCYCLE environment
- Mount the appropriate extension on the
internal measuring arm (B, fig. 26).

- Set the wheel's data as indicated in the "WHEEL
DATA ENTRY" chapter.
- Perform a spin.
- Proceed as described for dynamic balancing.
Motorcycle ALU Programme
Proceed as follows to balance motorcycle wheels
dynamically using adhesive weights:
- Follow the instructions for mounting the motor-
cycle adapter described in the MOTORCYCLE
DYNAMIC PROGRAMME.
Proceed as described previously for the "Motor-
cycle Dynamic" programme.
- Perform a spin.
- at the end of the spin, select the balancing

programme icon
knob or the ENTER button until the required
programme is selected.
- For the application of the adhesive weight, use
6 o'clock as the reference if the "LASER" confi-
guration is active and 12 o'clock if the "H12" or
"CLIP" configuration is active.
Best results can be achieved if the adhesive
weights are positioned with the outer edge being
flush with the rim edge.
Split Weight Programme
Some rims have spokes so wide that it is not
possible to place adhesive weights next to them;
a program which divides the counterweights
into two parts has been introduced to solve
this problem.
In this case, when the centred position is reached
and it becomes obvious that the balancing weight
will have to be applied in line with a spoke,
proceed as follows:
- Remain in the centred position.
- Select the
(displayed instead of the "select ALU pro-
grammes" icon).
- Select the spoke dimension on the displayed
window using the keypad: small, medium,
large or OFF (selection deactivated).
- Confirm by pressing the Kis knob or the
26
ENTER button.
- Apply two new counterweights in the posi-
tions indicated.
The weight division operations can be performed
on both balancing sides.
A wheel can be balanced using a single counter-
weight on one of its two sides or in the centre of
the well. in this case, the wheel is balanced stat-
ically. However, there is still the risk of dynamic
unbalance, which becomes more significant as
the width of the wheel increases.
Proceed as follows to balance motorcycle or car
wheels statically:
- Correctly set the wheel's geometric data as de-
scribed for the Dynamic balancing programme.
