Front Fork
Front
Fork Adjustment
The front fori< should
always
be adjusted for
the
rider's
weight and
track
conditi()(ls
by using one
or
more of the
following
methods.
Basically,
there
are five adjustment
you
can make
to
the
front fork..
OAir
pressure
-
Air pressure acts as a progressive spring
and
affects the
entire range of
forte travel.
The air
pressure
in
the fork
increases
as the
fork heats
up,
so the
fork action
on your KX will
get sl
iffer as
the race
progresses.
Because
of
this,
we
don't
recommended
using
air pressure
for
additional
springing.
Vour KX
forks are designed
to
work without adding any air.
O
Rebound
damping
adjustment
-
Th
is adjustment
affects how
quickly
the
fork
rebounds.
The
fork
rebound
damping
adjuster
has
16
clicks. The seated
position (full clockwise
until
the
adjuster
stops) is tull
hard,
and
16 clicks (full counterclockwise
untit
the
adjuster
SlOps) is full soft.
o
Compression
damping
adjustment
-
This adjustment
affects
how
quickly the foOt
compresses.
The
foOt
compression
damping
adjuster
has
16
clicks.
The
seated
position
(full counterclockwise until
the
adjuster
stops)
is
full soft. and 16 clicks (full clockwise until the
adjuster
stops) is full
hard.
OOillevel
adjustment
-
The
effects of
higher
or lower
foOt
oil
level
are only felt
during the
final
100 mm of
fork
travel.
A higher oil
level
(more
oil) will
make the
fork
rebound
more
qu
ickly.
A
lower
oil
level
<less oil) will
make the
foOt rebound more
slowly.
o
For
springs
-
Optional
springs
are
available that are
softer and stiffer
than
standard.
o
FoOt clamp position - Steering
qualities
are
greatly
affected
by
the foOt clamp
position
(If the
amount
of
the
outer tube projecting
above
the upper
fork
clamp)
.
When
the fork
tube height
is
smaller,
the
front
end
become
lighter
due
to
the change in
weight
bias.
Also,
it
toods
to understeer in
turns
and
·wash
out:
When
the
height is
greater,
the
results
are opposite.
