166 TECHNOLOGY IN DETAIL
Minimum speed for the
transmission of the TPC
measured values:
min 19 mph (min 30 km/h)
Before initial reception of the
tire pressure,
--
is shown in
the display for each tire. The
sensors continue to transmit
the measured readings for
some time after the vehicle
comes to a stop.
Transmission time of
the measured values af-
ter vehicle standstill:
min 15 min
If an RDC control unit is in-
stalled but the wheels have no
sensors, a fault memory entry is
generated.
Tire inflation pressure ranges
The RDC control unit distin-
guishes between three inflation
pressure ranges matched to
the motorcycle:
Tire pressure within the per-
missible tolerance
Tire pressure within the limit
range of the permissible toler-
ance
Tire pressure outside of the
permissible tolerance
Temperature compensation
The tire pressure is tempera-
ture dependent, i.e. it increases
or decreases together with the
tire air temperature. The tire
temperature is dependent on
the outside temperature, the
riding style and the length of
the journey.
The tire pressures
are shown in the TFT
display with temperature
compensation and are always
based on the following tire
air temperature:
68 °F (20 °C)
Tire pressure gages at gas sta-
tions do not make any com-
pensation for the air tempera-
ture, the tire pressure indicated
depends on the temperature
of the air in the tire. As a re-
sult, in most cases the values
displayed there do not match
the values shown in the TFT
display.
Tire pressure adjustment
Compare the RDC value in the
TFT display with the value on
the back cover of the Operat-
ing Instructions. The difference
between the two values must
be compensated with the tire
inflation pressure tester at the
filling station.
