BMW F800GT Rider's Manual page 94

Each sensor has a centrifugal-
8
force tripswitch that does not
enable transmission of the meas-
92
ured values until the vehicle has
accelerated to about 30 km/h.
The display shows "
tyre until the tyre-pressure signal
is received for the first time. The
sensors continue to transmit the
measured-value signals for ap-
proximately 15 minutes after the
motorcycle comes to a stop.
Temperature
compensation
Tyre pressure is a temperature-
sensitive variable: pressure in-
z
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-
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
­­
" for each 20 °C. The gauges on forecourt
air lines do not compensate for
temperature. The tyre pressure
registered 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 differen-
tiates between 3 tyre pressure
ranges, all of which are paramet-
rised for the vehicle:
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 forecourt 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.
