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).
RS90GT / RS90LTGT / RST90GT
RST90
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.

Adjusting the damping forces of the
front shock absorbers (RS90GT /
RS90LTGT / RST90GT)
WARNING
EWS00740
The damping forces of the left and right
shock absorbers must be adjusted to the
same settings. Uneven settings can cause
poor handling and loss of stability.
Compression damping force
The compression damping force of each
shock absorber can be adjusted by turning its
compression damping force adjusting knob.
