Maintenance
FRONT
FORK
The
front fork
legs of the 1982 model contain
compressed
air to
obtain adjustable suspension.
This
type of the front
fork
is especially effective
when the
fork is compressed. It
also has
the
advantage
that
any
air
pressure
can be
choosen
(wit
hin
the
usable range)
to
suit
various riding
conditions.
