ABS OPERATION
General specifications:
The front circuit is similar to the rear circuit.
•
The ABS inlet valve (10 - 11) is normally open and it is closed only when the system inter-
venes to avoid wheel locking.
•
The exhaust valve (12 - 14) is normally closed and is only opened when the system inter-
venes to prevent locking.
•
With the system in stand-by mode, the ABS processor controls the wheel speed instant by
instant to assess any slippage of the wheels.
•
When in standby, the system does not intervene at all when the rider brakes; the braking
system is the same as the one without ABS.
Stages in ABS cycle (the following operations refer to the front circuit but are also applicable to
the rear one):
A - Brake activation: the rider starts braking
as he would usually do.
