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 BWM Motorrad ASC is un-
able to control a situation of this
nature.
Tyre pressure
monitoring RDC
OE
FunctionA sensor integrated into each
tyre measures the air temperat-
ure 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.
Temperature
compensationThe tyre-pressure readings
shown by the multifunction
display are temperature-
compensated; the reference tyre
temperature for these readings
is always 20 °C. The air lines
available to the public in petrol
stations and motorway service
areas almost invariably show
temperature-dependent tyre
pressures, so in most instances
these gauge readings will not
tally with the readings shown by
the multifunction display.

Tyre-pressure rangesThe 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.

the on-board power supply sys-
tem is minimised, the supply to
the power socket is cut off ap-
proximately 15 minutes after the
ignition is switched off, and it is
also temporarily interrupted dur-
ing the start procedure.Cable routingThe cables from the power sock-
et to the auxiliary device must be
routed in such a way that they:Do not impede the rider
Do not restrict or obstruct the
steering angle and handling
characteristics
Cannot be trapped
Incorrectly routed cables
can impede the rider.
Route the cables as described
above.
LuggageCorrect loading
Overloading and imbal-
anced loads can adversely
affect the motorcycle's handling.
Do not exceed the permissible
gross weight and be sure to
comply with the instructions on
loading.
Set spring preload, damping
characteristic and tyre pres-
sures to suit total weight.
Adjust the spring preload for
rear wheel ( 61)
Check the tyre pressure
( 65)
Adjust the damping for rear
wheel ( 62)
Ensure that the case volumes
on the left and right are equal.
Make sure that the weight is
uniformly distributed between
right and left. Pack heavy items at the bot-
tom and toward the inboard
side.
Note the maximum permissible
payload of the cases and the
speed limit for riding with cases
on the motorcycle.
Payload of cases
max 8 kg Maximum permissible
speed for riding with
cases fitted to the motorcycle
max 180 km/h
Note the maximum permissible
payload of the tank rucksack.
Payload of tank rucksack
max 5 kg
Note the maximum permissible
payload of the tankbag.

fuse trips and de-energises a circuit, the circuit is
active as soon as the ignition is switched on after
the fault has been rectified.
