Take care when cornering.
When you apply the brakes
on a corner, the motorcycle's
weight and momentum take
over and even BMW Motor-
rad Integral ABS is unable to
counteract their effects.Electronic engine

How does BMW
Motorrad ASC work?The BMW Motorrad ASC
compares the speed of rota-
tion 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 electronic
engine management system
intervenes, adapting engine
torque accordingly.
What is the design
baseline for BMW
Motorrad ASC?BMW Motorrad ASC is de-
signed as an assistant system
for the rider and for use on
public roads. The extent to
which the rider affects ASC
control can be considerable
(weight shifts when cornering,
items of luggage loose on the
motorcycle), especially when
style of riding takes rider and
machine close to the limits
imposed by physics. The sys-
tem is not optimised for spe-
cial requirements that apply
under extreme competitive
situations off-road or on the
track. You have the option
of deactivating the BMW Mo-
torrad ASC for these circum-
stances.
Special situationsIn accordance with the laws
of physics, the ability to ac-
celerate is restricted more
and more as the angle of heel
increases. Consequently,
there can be a perceptible
lag in acceleration out of very
tight bends.
The speeds of the front and
rear wheels are compared
as one means of detecting a
wheel's incipient tendency to
lock. If the system registers
implausible values for a
lengthy period the ASC
function is deactivated
for safety reasons and
an ASC fault message is
issued. Self-diagnosis has
to complete before fault
messages can be issued.
