ted to a vehicle equipped with
an RDC control unit.
Tyre pressure ranges
The RDC control unit distin-
guishes between three tyre
pressure ranges matched to
the vehicle:
Tyre pressure within permit-
ted tolerance.
Tyre pressure close to limit of
permitted tolerance.
Tyre pressure outside permit-
ted tolerance.
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
temperature depends on ambi-
ent temperature as well as on
the style of riding and the dura-
tion of the ride.
The tyre pressures are
shown in the display as
temperature compensated
and always refer to the fol-
lowing tyre air temperature:
20 °C
The air lines available to the
public in petrol stations and
motorway service areas have
gauges that do not compensate
for temperature; the reading
shown by a gauge of this
nature is the temperature-
dependent tyre-air pressure. As
a result, the values displayed
there usually do not correspond
to the values displayed in the
display.
Pressure adaptation
Compare the RDC value on the
display with the value in the
table on the back cover of the
rider's manual. Then use the
air-line gauge at a service sta-
tion to compensate for the dif-
ference between the RDC read-
ing and the value in the table.
Example
According to the operating
instructions, the tyre pressure
should be:
2.5 bar
The following value is shown
in the display:
2.3 bar
So pressure is low by:
0.2 bar
The gauge on the air line
shows:
2.4 bar
You must now increase tyre
pressure until the value is:
2.6 bar
