er has a considerable influence
on the control options of the
ASC (shifting weight in curves,
loose loads).
The offroad mode can be activat-
ed when driving offroad. In this
mode the controlling intervention
by the ASC is carried out later,
enabling controlled drifting.
The system is not optimized for
special requirements resulting
under extreme weather condi-
tions offroad or on the racetrack.
The BMW Motorrad ASC can be
deactivated for these cases.
Even with ASC, physical
laws cannot be overridden.
The driver is always responsible
for adapting his/her driving style.
Do not reduce the additional
safety provided with risky
driving.
Special situations
At an increasing angle, the accel-
eration performance is increas-
ingly limited in accordance with
physical laws. This can result in
delayed acceleration when com-
ing 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 fault
is indicated. The condition for a
fault message is the completed
self-diagnosis.
In the following unusual driving
states, the BMW Motorrad ASC
can be automatically deactivated.
Unusual driving conditions:
Driving on the rear wheel
(wheely) for a longer period
with ASC deactivated.
Rear wheel spinning in place
with front brake pulled (burn
out).
Heating up on the main or aux-
iliary stand at idle or with gear
engaged.
The ASC is reactivated by
switching the ignition on and
off and then driving at a speed
above 6 mph (10 km/h).
With extremely massive-bar tires,
an ASC intervention can occur
before the optimum propulsion
is achieved due to the greater
slip involved. In these cases the
BMW Motorrad ASC should be
deactivated.
If the front wheel loses contact
to the ground during extreme
acceleration, the ASC reduces
the engine torque until the front
wheel touches the ground again.
In this case, BMW Motorrad rec-
ommends turning back the throt-
