Control functions
The spring preload can be adjusted by turning
the adjusting rings (PZ50MT / PZ50VT) or ad-
justing nuts (PZ50GT). Adjust the spring pre-
load as follows.
PZ50MT / PZ50VT
To increase the spring preload and thereby
harden the suspension, turn the adjusting ring
in direction (a). To decrease the spring pre-
load and thereby soften the suspension, turn
the adjusting ring in direction (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.
Spring preload setting*:
Minimum (soft):
168.6 mm (6.64 in)
Standard:
168.6 mm (6.64 in)
Maximum (hard):
178.6 mm (7.03 in)
* Distance A changes 1.5 mm (0.06 in)
with each full turn of the adjusting nut.
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.
