til a speed of approx. 18 mph
(30 km/h) is reached. Before ini-
tial reception of the tire inflation
--
pressure, is shown in the dis-
play for each tire. The sensors
continue to transmit the mea-
sured values for approx. 15 min-
utes after the vehicle comes to a
stop.
The control unit can manage four
sensors, and as a result two sets
of wheels with TCP/RDC sen-
sors can be driven. If a TCP/RDC
control unit is installed, however
the wheels have no sensors, then
a fault code is output.
Tire inflation pressure
ranges
The TPC/RDC control unit distin-
guishes between three tire infla-
tion pressure ranges matched to
the motorcycle:
Inflation pressure within the
permissible tolerance.
Inflation pressure at the limits
of the permissible tolerance.
Inflation pressure outside the
permissible tolerance.
Temperature
compensation
The tire inflation pressure is tem-
perature dependent, i.e., it in-
creases or decreases together
with the tire temperature. The
tire temperature is dependent on
the ambient temperature and on
the driving style and duration.
The tire inflation pressures are
shown temperature-compen-
sated in the multifunction display;
they refer to a tire temperature
of 68 °F (20 °C). No tempera-
ture compensation takes place in
the inflation pressure testers at
filling stations, meaning that the
measured tire inflation pressure
varies according to tire temper-
ature. As a result, the pressure
figures indicated by the gauges
at filling stations will usually vary
from those appearing in the mul-
tifunction display.
Adjusting inflation
pressure
Compare the TCP/RDC value in
the multifunction display with the
value on the back cover of the
Rider's Manual. The difference
between the two values must be
compensated with the air pres-
sure tester at the filling station.
Example: According to the
Rider's Manual, the tire inflation
pressure is to be 36 psi (2.5 bar),
however 33 psi (2.3 bar) is
shown in the multifunction
display. The tester at the
filling station indicates 34.8 psi
(2.4 bar). This value must be
increased by 3 psi (0.2 bar) to
