WARNING

serviced.
Risk of accident
In order to ensure that the
BMW Motorrad Race ABS is
z
always maintained in optimum
condition, it is essential for you
to comply strictly with the spe-
cified inspection intervals.
Reserves for safety
The potentially shorter braking
distances which BMW Motorrad
Race 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 Race ABS is un-
able to counteract their effects.
Evolution of Race ABS to
ABS Pro
OE
with ABS Pro
Until now, the BMW Motorrad
Race 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, partic-
ularly in panic-braking situations,
counteracting the vehicle's oth-
erwise 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
