Service Solution
WARNING
The replacement procedure of the rear brake hoses described in the document is not
particularly difficult, however, for the operation to be completed successfully and to
comply with the set time, it is necessary to thoroughly follow the sequence of the
indicated operations.
We recommend taking your time to fully understand the procedure before
attempting its implementation on the motorcycle (you may print the document in
color for a better understanding).
We also remind you that the work environment where you carry out the procedure
and the tools and equipment used (wrenches and gloves) must be clean.
NOTE
We hereby inform you that this operation is carried out exclusively on the primary
circuit of the rear brake system for which it is sufficient to perform the traditional
bleeding procedure; NO specific bleeding procedure is hence required for the
secondary circuit (circuit inside the ABS control unit).
