compensation
The tire inflation pressure is tem-
88
perature dependent, i.e. it in-
creases or decreases together
with the tire air temperature. The
tire air temperature is dependent
on the ambient temperature and
on the driving style and duration.
The tire inflation pressures are
shown temperature-compensated
in the multifunction display. They
refer to a tire air temperature of
68 °F (20 °C). No temperature
compensation takes place in the
inflation pressure testers at fill-
z
ing stations. The measured tire
inflation pressure is dependent
on the tire air temperature. As a
result, in most cases the values
displayed there do not match the
values shown in the multifunction
display.
Tire inflation pressure
ranges
The TPC/RDC control unit distin-
guishes between three pressure
ranges matched to the motorcy-
cle:
Inflation pressure within the
permissible tolerance.
Inflation pressure at the limits
of the permissible tolerance.
Inflation pressure outside the
permissible tolerance.
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 psi (2.5 bar),
however 33 psi (2.3 bar) is
shown in the multifunction
display. The tester at the
filling station indicates 34.8 psi
(2.4 bar). This value must be
increased by 3 psi (0.2 bar) to
37.8 psi (2.6 bar) in order to
produce the correct tire inflation
pressure.
