with tire pressure monitor (TPM)
A sensor located in each tire monitors the
air temperature and the tire pressure and
transmits this information to the control unit.
The sensors are equipped with a centrifu-
gal controller, which does not enable the
transmission of the measured values until
the minimum speed of min 19 mph (min
30 km/h) is exceeded for the first time.
Before initial reception of the tire pressure,
-- is shown in the display for each tire. The
sensors continue to transmit the measured
values for min 15 min after the vehicle
comes to a stop.
If an RDC control unit is installed but the
wheels have no sensors, a fault message is
Tire inflation pressure ranges
The RDC control unit distinguishes between
three inflation pressure ranges matched to
the motorcycle:
Tire pressure within the permissible toler-
Tire pressure at the limits of the permissi-
ble tolerance.
Tire pressure outside the permissible tol-
Temperature compensation
The tire pressure is temperature dependent,
i.e. it increases or decreases together with
the tire air temperature. The tire tempera-
ture is dependent on the outside tempera-
ture, the riding style and the length of the
The tire pressures are shown in the mul-
tifunction display with temperature com-
pensation and are always based on a tire air
temperature of 68 °F (20 °C).
Tire pressure gauges at filling stations do
not make any compensation for the tire air
temperature, the tire pressure indicated de-
pends on the temperature of the air in the
tire. As a result, in most cases the values
displayed there do not match the values
shown in the display.
Tire pressure adjustment
Compare the RDC value in the display with
the value on the back cover of the operat-
ing instructions. The difference between the
two values must be compensated with the
tire inflation pressure tester at the filling sta-
According to the Operating Instructions,
the tire pressure should have the follow-
ing value:
36.3 psi (2.5 bar)
The following value is displayed in the
TFT display:
33.4 psi (2.3 bar)
The shortfall is thus:
2.9 psi (0.2 bar)
The tester at the filling station shows:
34.8 psi (2.4 bar)
To produce the correct tire pressure, this
must be increased to the following value:
37.7 psi (2.6 bar)
with Hill Start Control
Hill Start Control function
The Hill Start Control ride-off assistant func-
tion prevents uncontrolled rolling back on
slopes by means of targeted intervention in
the fully integral ABS brake system without
the rider having to continuously operate the
brake lever. When Hill Start Control is acti-
vated, pressure builds in the rear brake sys-
tem so that the motorcycle remains station-
ary on a sloping surface. The brake pressure
in the brake system depends on the gradi-
Influence of gradient on brake pressure
and starting behavior
Stopping on a slight incline builds up only
a small amount of brake pressure. The
brake is released quickly when riding
off, making it possible to ride off more
