What is the design
baseline for
BMW Motorrad ASC?
BMW Motorrad ASC is designed
as an assistant system for the
rider and for use on public roads.
The extent to which the rider af-
fects the ASC can be consider-
able (weight shifts when corner-
ing, items of luggage loose on
the motorcycle), especially when
style of riding takes rider and ma-
chine close to the limits imposed
by physics.
The system is not optimised for
special requirements that apply
under extreme competitive situ-
ations off-road or on the track.
You have the option of deactiv-
ating the BMW Motorrad ASC
system for these circumstances.
Even ASC is constrained by
the laws of physics. Invari-
ably, the rider bears responsibil-
ity for assessing road and traffic
conditions and adopting his or
her style of riding accordingly.
Do not take risks that would neg-
ate the additional safety offered
by this system.
Special situations
In accordance with the laws of
physics, the accelerating ability
is restricted more and more as
the heel angle increases. Con-
sequently, there can be a per-
ceptible lag 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.
The BMW Motorrad ASC can
switch off automatically under
the exceptional riding conditions
outlined below.
Exceptional riding
conditions:
Riding for a lengthy period with
the front wheel lifted off the
ground (wheelie) and ASC de-
activated.
Rear wheel rotating with the
vehicle held stationary by ap-
plying the front brake (burn-
out).
Heating up with the motorcycle
on the centre stand or an auxil-
iary stand, engine idling or with
a gear engaged.
Accelerating the motorcycle to
a speed in excess of 5 km/h
after switching the ignition off
and then on again reactivates the
ASC.
