(ASC) OE
How does the ASC work?
BMW Motorrad ASC compares
the wheel speeds of the front
and rear wheel. From the speed
difference the slip, and with it
the stability reserves on the rear
wheel are determined. When a
slip limit is exceeded, the engine
torque is adapted by the engine
management system.

What are the design
characteristics of the
BMW Motorrad ASC?
BMW Motorrad ASC is designed
as an assistant system for the
rider for the use on public roads.
The extent to which the rider af-
fects ASC control can be consid-
erable (weight shifts when cor-
nering, 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 optimized for
special requirements resulting
under extreme weather condi-
tions offroad or on the racetrack.
BMW Motorrad ASC can be de-
activated for these cases.
WARNING
Risky riding style.
Accident hazard despite ASC.
The rider is always responsi-
ble for adapting his/her driving
style.
Do not reduce the system's ex-
tra safety margin with careless
riding or unnecessary risks.
Special situations
As lean angles increase, accel-
eration potential is also progres-
sively restricted by the laws of
physics. This can result in de-
layed acceleration when coming
out of very tight curves.
To detect spinning or slipping
away of the rear wheel, the
speeds of the front and
rear wheel are compared. If
implausible values are detected
over a longer period of time, the
ASC function is deactivated for
safety reasons and an ASC error
is indicated. The condition for a
fault code is the completed self-
diagnosis.
The following unusual driving
conditions may lead to automatic
deactivation of BMW Motorrad
