wheels without sensors are fitted
to a motorcycle equipped with an
RDC control unit.
Temperature
compensation
Tyre pressure is a temperature-
sensitive variable: pressure in-
creases as tyre air temperature
rises and decreases as tyre air
temperature drops. Tyre air tem-
perature depends on ambient
temperature, on the style of rid-
z
ing and the duration of the ride.
The tyre-pressure readings
shown by the multifunction
display are temperature-
compensated. They are based
on a tyre air temperature of
20 °C. The gauges on forecourt
air lines do not compensate for
temperature. The tyre pressure
recorded depends on tyre air
temperature. In most instances,
therefore, these gauge readings
will not tally with the pressures
shown by the multifunction
display.
Tyre-pressure ranges
The RDC control unit differenti-
ates between three tyre-pressure
ranges, all of which are paramet-
erised for the motorcycle:
Tyre pressure within permitted
tolerance
Tyre pressure close to limit of
permitted tolerance
Tyre pressure outside permit-
ted tolerance
Pressure adaptation
Compare the RDC value on the
multifunction display with the
value in the table on the back
cover of the Rider's Manual.
Then use the air line at a service
station to compensate for the
difference between the RDC
reading and the value in the
table.
Example: according to the
Rider's Manual, tyre pressure
should be 2.5 bar, but the
reading in the multifunction
display is 2.3 bar. The gauge on
the air line shows 2.4 bar. You
must now increase tyre pressure
by the 0.2 bar difference
between the value in the table
and the RDC reading; when the
air-line gauge shows 2.6 bar,
the tyre is inflated to the correct
pressure.
