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
with ABS Pro
OA
Until now, the BMW Motorrad
Race ABS of the S 1000 RR
helped ensure a very high degree
of safety for braking with the mo-
torcycle upright and travelling
in a straight line. Now ABS Pro
offers enhanced safety for brak-
ing in corners as well. ABS Pro
prevents the wheels from lock-
ing even under sharp braking.
ABS Pro reduces abrupt changes
in steering force, particularly in
panic-braking situations, coun-
teracting 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 Con-
trol DTC and Dynamic Damping
Control DDC.
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.
Advantages for the rider
The advantages of ABS Pro for
the rider are sensitive response
and high braking and directional
stability combined with best-case
deceleration of the motorcycle,
even when cornering.
NOTICE
ABS Pro is available only in
the
RAIN
and
SPORT
riding
modes.
