BMW R 1200 RT 2011, Rider'S Manual

Page: 84 / 161

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.

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 motorcycle
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 sig-
nals for approximately 15 minutes
after the motorcycle comes to a
stop.
The control unit can adminis-
trate four sensors, so two dif-
ferent sets of wheels with RDC
sensors can be alternated on
the motorcycle. An error mes-
sage is issued if wheels without
sensors are fitted to a motorcycle
equipped with an RDC control
unit.
Tyre-pressure ranges
The RDC control unit differenti-
ates between three tyre-pressure
ranges, all of which are paramet-
erised for the motorcycle:
Tyre pressure within permitted
tolerance.
Tyre pressure close to limit of
permitted tolerance.
Tyre pressure outside permit-
ted tolerance.
