a fall can result. Before this sit-
uation occurs, ABS is activated
90
and the brake pressure is ad-
justed to the maximum transfer-
able braking force. This enables
the wheels to continue to turn
and maintains driving stability re-
gardless of the road surface con-
dition.
What happens when
rough roads are
encountered?
Bumpy or rough roads can briefly
lead to a loss of contact be-
tween the tires and the road sur-
z
face, until the transferable brak-
ing force is reduced to zero. If
braking is carried out in this sit-
uation, ABS must reduce the
brake pressure to ensure driv-
ing stability when restoring con-
tact to the road. At this point in
time, the BMW Motorrad Integral
ABS must assume extremely low
friction coefficients (gravel, ice,
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.
How is the BMW Motorrad
Integral ABS noticeable to
the rider?
If the ABS system must reduce
the braking forces due to the
conditions described above, then
vibrations can be felt at the hand-
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 deceleration it is possi-
ble that the BMW Motorrad Inte-
gral ABS will not prevent the rear
wheel from lifting off the ground.
In these cases, the motorcycle
can also flip end over end.
Heavy braking can lead to
the rear wheel lifting off the
ground.
When braking, bear in mind
that the ABS control cannot
always be relied on 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 stability on any
surface within the limits of driv-
ing physics. The system is not
