What significance
devolves on regular
maintenance?
WARNING
Brake system not regularly
serviced.
Risk of accident
In order to ensure that the ABS
is always maintained in op-
timum condition, it is essen-
tial for you to comply strictly
with the specified inspection
intervals.
Reserves for safety
The potentially shorter braking
distances which BMW Motorrad
Integral ABS permits must not be
used as an excuse for careless
riding. ABS is primarily a means
of ensuring a safety margin in
genuine emergencies.
Take care when cornering! When
you apply the brakes on a corner,
the motorcycle's weight and
momentum take over and even
BMW Motorrad Integral ABS is
unable to counteract their effects.
Evolution of ABS to
ABS Pro
Until now, the BMW Motorrad
ABS helped ensure a very high
degree of safety for braking
with the motorcycle upright
and travelling in a straight line.
Now ABS Pro offers enhanced
safety for braking in corners
as well. ABS Pro prevents the
wheels from locking even under
sharp braking. ABS Pro reduces
abrupt changes in steering
force, particularly in panic-
braking situations, counteracting
the vehicle's otherwise natural
but undesirable tendency to
straighten up.
ABS intervention
Technically speaking, depending
on the riding situation ABS Pro
adapts ABS intervention to the
motorcycle's bank angle. Signals
for rate of roll and rate of yaw
and lateral acceleration are used
to calculate bank angle. These
signals come from the angular
rate sensor, an integral compon-
ent of Dynamic Traction Control
DTC and Dynamic ESA.
As the motorcycle is heeled over
more and more as it banks into
a corner, an increasingly strict
limit is imposed on the brake-
pressure gradient for the start of
brake application. This slows the
build-up of brake pressure to a
corresponding degree. Addition-
ally, pressure modulation is more
uniform across the range of ABS
intervention.
