Bmw Motorrad Integral Abs - BMW R 1200 R Rider's Manual

which the brake pressure is
generated as quickly as pos-
sible and with great force, the
dynamic load distribution can-
not follow the increased de-
celeration and the braking
force cannot be completely
transferred to the road sur-
face. To prevent the front
wheel from locking, the ABS
system must intervene and
reduce the brake pressure;
the braking distance increas-
es.
Rear wheel lift
Even during severe braking,
a high level of tire grip can
mean that the front wheel
does not lock up until very
late, if at all. Consequently,
ABS does not intervene until
very late, if at all. Under these
circumstances the rear wheel
can lift off the ground, and the
outcome can be a highsiding
situation in which the motor-
cycle can flip over.
Severe braking can
cause the rear wheel to
lift off the ground.
When braking, bear in
mind that the ABS control
cannot be relied on in all
circumstances to prevent the
rear wheel from lifting off the
ground.
What are the design
characteristics of the
BMW Motorrad Integral
ABS?
The BMW Motorrad Integral
ABS ensures driving stabili-
ty on any surface within the
limits of driving physics. The
system is not optimized for
special requirements result-
ing under extreme weather
conditions offroad or on the
racetrack.
Special situations
To detect the tendency of the
wheels to lock up, the speeds
of the front and rear wheel
are compared. If implausible
values are detected over a
longer period of time, the ABS
function is deactivated for
safety reasons and an ABS
fault is indicated. The condi-
tion for a fault message is the
completed self-diagnosis.
In addition to problems on
the BMW Motorrad Integral
ABS, unusual driving condi-
tions can also lead to a fault
message.
Unusual driving conditions:
Heating up on the main or
auxiliary stand at idle or with
gear engaged.
Rear wheel locked-up for a
longer period of time by en-
gine brake, e.g. when riding
downhill offroad.
