Electronic engine
management with

BMW Motorrad ASC

How does ASC work?
z
BMW Motorrad ASC 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 control inter-
venes and adapts the engine
torque accordingly.
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 ASC control can be consid-
erable (weight shifts when cor-
nering, items of luggage loose on
the motorcycle), especially when
the style of riding takes the rider
and machine close to the limits
imposed by physics.
For off-road driving, the
ENDURO riding mode should be
activated. This mode delays ASC
intervention slightly in order to
permit controlled drifting.
The system is not optimised for
special requirements that apply
under extreme competitive situ-
ations off-road or on the track.
BMW Motorrad ASC can be de-
activated in these cases.
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 ability to accelerate
is restricted more and more as
the angle of heel 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-
