Control functions

Rebound damping force
The rebound damping force of each shock
absorber can be adjusted by turning its re-
bound damping force adjusting knob.
To increase the rebound damping force, turn
the adjusting knob in direction (a). To de-
crease the rebound damping force, turn the
adjusting knob in direction (b).
TIP
The damping forces will not decrease past the
minimum levels even if the adjusting knobs
are turned out more than the minimum set-
tings.
ESU13082
Adjusting the spring preload of the
rear shock absorber
The spring preload can be adjusted by turning
the adjusting nut on the rear shock absorber.
Adjust the spring preload as follows.
1.
Loosen the locknut.
2.
To increase the spring preload and there-
by harden the suspension, turn the ad-
justing nut in direction (a). To decrease
the spring preload and thereby soften the
suspension, turn the adjusting nut in di-
rection (b).
TIP
The spring preload setting is determined by
measuring distance A, shown in the illustra-
tion. The longer distance A is, the higher the
spring preload; the shorter distance A is, the
lower the spring preload.
3.
Tighten the locknut to the specified
torque.
NOTICE:
Always tighten the
locknut against the adjusting nut, and
then tighten the locknut to the speci-
fied torque.
