Reserves for safety
The potentially shorter braking
distances which BMW Motorrad
ABS permits must not be used
as an excuse for careless riding.
ABS is primarily a means of en-
suring a safety margin in genuine
emergencies.
Take care when cornering! When
you apply the brakes on a corner,
the vehicle's weight and mo-
mentum take over and even
BMW Motorrad ABS is unable
to counteract their effects.
Automatic Stability
Control (ASC)
How does ASC work?
The BMW Motorrad ASC system
compares the speed of rotation
of the front wheel and the rear
wheel. The differential is used
to compute slip as a measure of
the reserves of stability available
at the rear wheel. If slip exceeds
a certain limit, the engine man-
agement system intervenes and
adapts engine torque accordingly.
Special situations
In accordance with the laws of
physics, the ability to accelerate
is restricted more and more as
the angle of heel increases. Con-
sequently, there can be a per-
ceptible reduction in acceleration
out of very tight bends.
The speeds of the front and
rear wheels are compared as
one means of detecting the rear
wheel's incipient tendency to
spin or slip sideways. If the sys-
tem registers implausible values
for a lengthy period the ASC
function is deactivated for safety
reasons and an ASC fault mes-
sage is issued. Self-diagnosis
has to complete before fault
messages can be issued.
Riding for a lengthy period with
the front wheel lifted off the
ground (Wheelie) would result
in automatic shutdown of the
BMW Motorrad ASC.
If the front wheel lifts clear of the
ground under severe accelera-
tion, the ASC reduces engine
torque until the front wheel re-
gains contact with the ground.
Under these circumstances,
BMW Motorrad recommends
rolling the throttle slightly closed
so as to restore stability with the
least possible delay.
Never snap the throttle grip
closed when riding on a slippery
surface. Engine braking torque
can cause the rear wheel to lock,
with a corresponding loss of
stability. The BMW Motorrad
ASC is unable to control a
situation of this nature.
