considerable difference in shape that may
be found on rims having the same rated
dimensions. Therefore modify the value and
position the previously applied weights for
accurate wheel balancing.
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 rec-
ommended procedure).
- Dynamic mode for alloy rims; a programme
similar to the ALU programmes for car
wheels.
- 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 as shown in Fig. 17;
- insert the two screws that are supplied in
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 central hole) onto the shaft after
removing the threaded hub;
- mount the wheel after selecting the centring
58
cones (one for each side of the wheel),
tighten with the appropriate ring nut us-
ing 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.

- Mount the relative extension (Fig.17 a) on
the internal measuring arm.
Remember to remove this extension before
performing the wheel spin.
- Set the wheel data as usual.
- Proceed as described for dynamic balanc-
ing.
