Compare the RDC readings
on the multifunction display
67
with the value in the table on
the inside cover of the Rider's
Manual. Then use the air line 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 air line shows 2.4 bar. You
must now increase tyre pressure
z
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.
