extreme conditions there is a
possibility of the motorcycle
flipping over backwards.
Mode changes
The riding mode can be changed
while the vehicle is stationary
with the ignition on. It is possible
to change it while driving under
the following conditions:
No drive torque on the rear
wheel.
No brake pressure in the brake
system.
The following steps must be
taken to change the riding mode:
Close the throttle twistgrip.
Release the brake levers.
The desired riding mode is ini-
tially preselected. The mode
change does not take place until

Tyre pressure control

(RDC)

with tyre pressure control
OE
(RDC)
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.
The sensors are fitted with a
centrifugal-force trip switch which
allows the measured values to be
transmitted after the minimum
speed is exceeded the first time.
Minimum speed for
transmission of the RDC
measured values:
min 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 some
time after the vehicle comes to a
stop.
Transmission duration
of the measured values
after vehicle standstill:
min 15 min
An error message is issued if
wheels without sensors are fit-
ted 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-
rised for the motorcycle:
Tyre pressure within permitted
tolerance.
Tyre pressure close to limit of
permitted tolerance.
