The BMW Motorrad ASC can
shut down automatically under
the exceptional riding conditions
outlined below.
Exceptional riding
conditions:
Riding for a lengthy period with
the rear wheel lifted off the
ground (wheelie) with 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.
If the front wheel lifts clear of the
ground under severe accelera-
tion, the ASC reduces engine
torque until the front wheel re-
gains contact with the ground.
Under these circumstances,
BMW Motorrad recommends
rolling the throttle slightly closed
so as to restore stability with the
least possible delay.
When riding on a slippery sur-
face, never snap the throttle
twistgrip fully closed without
pulling the clutch at the same
time. Engine braking torque can
cause the rear wheel to lock, with
a corresponding loss of stability.
The BMW Motorrad ASC is un-
able to control a situation of this
nature.
Tyre pressure
monitoring RDC
with tyre pressure monitoring
(RDC)
OE
Function
A sensor integrated into each
tyre measures the air tempera-
ture and the air pressure inside
the tyre and transmits this in-
formation to the control unit.
Each sensor has a centrifugal-
force tripswitch that does not
enable transmission of the meas-
ured values until the vehicle has
accelerated to about 30 km/h.
The display shows -- for each
tyre until the tyre-pressure signal
is received for the first time. The
sensors continue to transmit the
measured-value signals for ap-
proximately 15 minutes after the
vehicle comes to a stop.
