3. Locknut
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.
Spring preload setting*:
Minimum (soft):
