Overhauling the front wheel rim, spokes and nipples
Perform a visual check for damaged parts: if no components are damaged check the nipple tightening and
axial and radial runout, as described below.
In case of runout, replace the rim.
In case of broken spokes replace them as described below: if three or more spokes broken at the same
time, it is necessary to check all spokes since such a high number of broken spokes not due to critical
events could mean that they were faulty and/or the installation/maintenance were not performed correctly.
Check for not spokes emitting a hollow sound when hit with a metallic object: this could mean that there
are loosen spokes that have been used for a long time without preload: in this case, check the threaded
coupling to the nipple and the seat in the spoke head hub.
Checking the nipple minimum tightening torque
This operation can be performed also with wheel fitted on the motorcycle, by lifting it from the ground and
ensuring it can rotate freely.
Starting from the valve hole as reference point, no matter if clockwise or counter clockwise, check the
minimum tightening torque of all nipples (11) once and one after the other and stop at the valve hole: the
minimum torque must be 4 Nm. The wrench to be used is tool (A) no. 88713.2776.
