ABS off-road setting (ABS ENDURO)
When this warning is activated, it is necessary to ride
carefully because the ABS setting in use is the one
devised for off road use and only the front wheel
braking is controlled by the system.
This warning is activated whenever ABS level 01 is
selected.
Warning
In this case, Ducati recommends to ride
carefully and use this type of ABS setting NOT for
road, but for off-road use only.
