FRONT FORK
CLEANING THE DUST SEAL
If
dusty
or
muddy
roads are frequently driven on
it
is
advisable
to
clean
the dust seal regularly
in
order
to
maintain the suspension
at
maximum
efficiency,
In fact,
if
dust
infiltrates to
the inside
of
the dust seal
it
can compromise the smoothness,
and
therefore
the
sensitivity of
the suspension, and also cause
the
premature wear
of
the underlying
oil
seal-
Just a
few simple operations then, guided by
the
following indications are necessary
to
maintain the
optimum
functioning of the
suspension
with time,
