of wheels with TPC/RDC sen-
sors can be driven. If a TPC/RDC
control unit is installed, however
the wheels have no sensors, then
a fault code is output.
Tire inflation pressure
ranges
The TCP/RDC control unit dis-
tinguishes between 3 inflation
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 outside 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 tyre 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 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 36.3 psi
(2.5 bar), however 33.4 psi
(2.3 bar) is shown in the
multifunction display. This means
the tires are underinflated by
2.9 psi (0.2 bar). The tester
at the filling station indicates
34.8 psi (2.4 bar). This value
must be increased by 2.9 psi
(0.2 bar) to 37.7 psi (2.6 bar) in
order to produce the correct tire
inflation pressure.
