braking is possible.
Behaviour during accidental
actuation of the throttle grip
If the throttle is accidentally
opened (throttle grip posi-
tion > 5 %) during emergency
braking, Dynamic Brake Con-
trol ensures the desired brak-
ing effect by ignoring actu-
ation of the throttle grip. The
effectiveness of emergency
braking is ensured.
If the throttle is closed
(throttle grip position < 5 %)
while Dynamic Brake Control
is in action, the engine torque
requested by the ABS brake
system is restored.
If emergency braking
ceases and the rider still
has not changed the po-
sition of the throttle grip,
Dynamic Brake Control
steadily ramps engine torque
back to the rider's requested
level.
The function of the
Dynamic Brake Control is
switched off at the same time
as the ABS is switched off.
TYRE PRESSURE CONTROL
(RDC)
with tyre pressure control
(RDC)
OE
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 tripswitch
which allows the measured val-
ues 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
tyre until the tyre-pressure sig-
nal is received for the first time.
The sensors continue to trans-
mit 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-
