Tyre Pressure Monitoring Rdc; Rdc - BMW K 1300 R Rider's Manual

If the front wheel lifts clear of the
6
ground under severe accelera-
tion, the ASC reduces engine
76
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
z
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 vehicle has
accelerated to about 30 km/h.
--
The display shows
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.
The control unit can manage four
sensors, so two different sets of
wheels with RDC sensors can
be alternated on the vehicle. An
error message is issued if wheels
without sensors are fitted to a
vehicle 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.

Temperature
compensation
Tyre pressure is a temperature-
sensitive variable: pressure in-
creases as tyre temperature rises
and decreases as tyre temper-
ature drops. Tyre temperature
depends on ambient tempera-
