Spring preload
Adjust the spring preload by turning the
spring preload adjusting bolt and align-
ing the match mark with the “
” mark
on the shock absorber assembly.
To increase the spring preload and
thereby harden the suspension, turn
the adjusting bolt in direction (a). To de-
crease the spring preload and thereby
soften the suspension, turn the adjust-
ing bolt in direction (b).
Rebound damping force
To increase the rebound damping force
and thereby harden the rebound damp-
ing, turn the adjusting screw in direction
(a). To decrease the rebound damping
force and thereby soften the rebound
damping, turn the adjusting screw in di-
rection (b).
Compression damping force
Compression damping force (for fast
