Driving on the rear wheel
(wheelie) for a longer period
with ASC deactivated
Rear wheel spinning in place
with front brake engaged (burn
out)
Heating up on the main or ad-
ditional stand at idle or with
gear engaged
Switching the ignition off and on
again and then riding the motor-
cycle at a speed of over 6 mph
(10 km/h) reactivates the ASC.
With extremely massive-bar tyres,
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.
BMW Motorrad recommends
that you respond to this condi-
tion by twisting back the throttle
grip somewhat to return to stable
dynamic operating conditions as
quickly as possible.
On a slippery surface, the throt-
tle grip should never be suddenly
twisted back completely unless
the clutch is disengaged at the
same time. The engine's brak-
ing torque could cause the rear
wheel to lock, resulting in un-
stable vehicle conditions. This
situation cannot be controlled by
the BMW Motorrad ASC.
Tyre Pressure Control
TPC
with Tire Pressure Control
(TPC)
OE
Function
A sensor is located in each tire,
which measures the air temper-
ature and the inflation pressure
inside the tire and sends these
values to the control unit.
The sensors are equipped with
a centrifugal controller, which
does not enable the transmis-
sion of the measured values until
after a speed of approx. 18 mph
(30 km/h) is exceeded for the
first time. Before initial recep-
tion of the tire inflation pressure,
-- is shown in the display for
each tire. The sensors continue
to transmit the measured values
for approx. 15 minutes after the
vehicle comes to a stop.
If a TCP control unit is installed,
however the wheels have no
