Tire pressure control
(TPC/RDC)
with tire pressure monitor
(TPM)
OE
Operation
A sensor located in each tire
monitors the air temperature and
the inflation pressure inside the
tire and transmits this information
to the control unit.
The sensors are equipped with a
switch that suppresses transmis-
sion of the measured values until
a speed of approximately 19 mph
(30 km/h) is reached. Before ini-
tial reception of the tire pressure,
­­
is shown in the display for
each tire. The sensors continue
to transmit the monitored data
for approx. 15 minutes after the
motorcycle comes to a stop.
A fault message is generated if a
TPM control unit is fitted but the
wheels have no sensors.
Temperature
compensation
The inflation pressure within a
tire is sensitive to temperature:
it responds to higher tire tem-
peratures by increasing, and to
lower temperatures by dropping.
Tire temperature, in turn, varies
according to the ambient temper-
ature as well as in response to
driving style and trip duration.
The tire pressures are shown
temperature-compensated in the
multifunction display; they refer
to a tire temperature of 68 °F
(20 °C). No temperature com-
pensation is available in the in-
flation pressure gauges at filling
stations, meaning that the mea-
sured tire inflation pressure varies
according to tire temperature.
As a result, the pressure figures
indicated by the gauges at fill-
ing stations will usually vary from
those appearing in the multifunc-
tion display. The warmer the tire,
the more the tester reading ex-
ceeds the display value.
Adjusting inflation
pressure
Compare the TPC/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 42 psi (2.9 bar),
however 39 psi (2.7 bar) is
shown in the multifunction
display. The tester at the filling
station indicates 36 psi (2.5 bar).
This value must be increased by
3 psi (0.2 bar) to 39 psi (2.7 bar)
