SHOCK ABSORBER INSPECTION
1. Inspect:
•Shock absorber
Oil leak/Damaged ➔Replace.
REAR SHOCK ABSORBER ADJUSTMENT
This shock absorber is equipped with a spring pre-
load adjuster.



 

Never attempt to turn an adjusting mecha-
nism beyond the maximum or minimum set-
tings.
CAUTION:
Adjust the spring preload as follows.
1. Loosen the locknut.
2. To increase the spring preload and thereby harden the suspension, turn the adjusting nut
in direction a. To decrease the spring preload
and thereby soften the suspension, turn the
adjusting nut in direction b.
NOTE:
•Use the special wrench included in the
owner's tool kit to make the adjustment.
•The spring preload setting is determined by
measuring distance A, shown in the illustra-
tion. The longer distance A is, the lower the
spring preload; the shorter distance A is, the
higher the spring preload. With each com-
plete turn of the adjusting nut, distance A
changes by 1.5 mm.
Spring preload: Minimum (soft):Distance A = 217 mm
Standard: Distance A = 211 mm
Maximum (hard): Distance A = 205 mm
