- Some slight residual unbalances may remain at
the end of the test spin due to the considerable
difference in shape that may be found on rims
having the same rated dimensions. Therefore
change the value and position of the previously
applied weights based on the configuration
performed in the programme "SELECTION OF
ADHESIVE WEIGHTS APPLICATION POSITION"
until an accurate balance is obtained.
Motorcycle Wheel Balancing
Motorcycle wheels can be balanced in:
- Dynamic mode; when the wheel width is such
(over 3 inches) to generate significant unbalance
components which cannot be eliminated with
static balancing (the recommended procedure).
- Dynamic mode for alloy rims; a programme
similar to the ALU programmes for on-vehicle
wheels, featuring the possibility of dividing
the weight of one side into two parts in case of
particularly large spokes.
- Static mode; just one balancing weight, divided,
if necessary, into equal parts on the two sides;
procedure described in the STATIC BALANCING
section.
Motorcycle Dynamic
Programme
Proceed as follows to balance a motorcycle
wheel on two planes (dynamic balancing) using
clip weights:
- Fit the motorcycle wheel adapter AUMO on
the wheel balancer (A fig. 26).
• Insert the two screws provided into the holes
on the wheel contact flange.
• Tighten the screws on the adapter making
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.
- When applying the adhesive weight, always
use the 12 o'clock position as your reference,
