snow) so that the running wheels
turn in every imaginable case and
the driving stability is ensured.
After detecting the actual con-
ditions, the system adjusts the
optimum brake pressure.
In what ways is the
Integral ABS noticeable
to the rider?
If the ABS system has to reduce
the braking force due to the con-
ditions described above, then
vibrations can be felt through the
handlebar brake lever.
If the handbrake lever is pulled,
then braking pressure is built up
at the rear wheel with the integral
function. If the footbrake lever is
first actuated after this, the brake
pressure already built up can be
felt earlier than the counter-pres-
sure, than when the footbrake
lever is actuated before or to-
gether with the handbrake lever.
Lifting off rear wheel
However, during extremely heavy
and rapid decelerations it is pos-
sible that the BMW Motorrad In-
tegral ABS cannot prevent the
rear wheel from lifting off the
ground. In these cases, the mo-
torcycle can also flip end over
end.
WARNING
Lifting off of the rear wheel
due to heavy braking
Accident hazard
When braking heavily, bear in
mind that the ABS control can-
not always be relied on to pre-
vent the rear wheel from lifting
off the ground.
What are the design
characteristics of the
Integral ABS?
The BMW Motorrad Integral ABS
ensures driving stability on any
surface within the limits of driv-
ing physics. The system is not
optimized for special require-
ments resulting under extreme
weather conditions off-road or on
the racetrack. Handling should
be adopted to driving skills and
road conditions.
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 an extended
period of time, the ABS function
is deactivated for safety reasons
and an ABS fault is indicated. A
self-diagnosis routine must be
completed before the error will
be displayed.
