compensation
The tire pressure is temperature-
92
dependent, i.e. it increases or
decreases together with the tire
air temperature. Tire air temper-
ature, in turn, varies according to
the ambient temperature, as well
as in response to riding style and
trip duration.
The tire pressures are shown
with temperature compensation
in the multifunction display. They
are based on a tire air temper-
ature of 68 °F (20 °C). No tem-
perature compensation is applied
z
in tire pressure testers at filling
stations. The measured tire pres-
sure 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 pressure should
be 36 psi (2.5 bar); in the multi-
function display, 33 psi (2.3 bar)
is shown. The tester at the fill-
ing 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 pro-
duce the correct tire pressure.
