INSTRUMENT AND CONTROL FUNCTIONS
3
1. Spring preload adjusting bolt
2. Alignment marks
To increase the spring preload and
thereby hardening it, turn the ad-
justing bolt in direction (a) from the
standard position, making sure to
turn the bolt complete turns so that
the alignment marks match.
To decrease the spring preload
and thereby softening it, turn the
adjusting bolt in direction (b) from
the standard position, making sure
to turn the bolt complete turns so
that the alignment marks match.
Spring preload setting:
Minimum (soft):
11 complete turns in direction (b)
from the standard position
Standard position:
See explanations above.
Maximum (hard):
2 complete turns in direction (a)
from the standard position
Rebound damping force
1. Rebound damping force adjusting bolt
To increase the rebound damping force
and thereby harden the rebound damp-
ing, turn the adjusting bolt on each fork
leg in direction (a). To decrease the re-
bound damping force and thereby soft-
en the rebound damping, turn the
adjusting bolt on each fork leg in direc-
tion (b).
3-22
Rebound damping setting:
Minimum (soft):
17 click(s) in direction (b)*
Standard:
12 click(s) in direction (b)*
Maximum (hard):
1 click(s) in direction (b)*
* With the adjusting bolt fully turned in
direction (a)
Compression damping force
1. Compression damping force adjusting bolt
To increase the compression damping
force and thereby harden the compres-
sion damping, turn the adjusting bolt on
each fork leg in direction (a). To de-
crease the compression damping force
and thereby soften the compression
damping, turn the adjusting bolt on
each fork leg in direction (b).
