Adjusting The Shock Absorber Assembly - Yamaha WR25R 2008 Owner's Manual

Adjusting the shock absorber
assembly
This shock absorber assembly is
equipped with a spring preload adjust-
ing ring, a rebound damping force ad-
justing dial and a
damping force adjusting screw.
NOTICE
To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.
Spring preload
Spring preload adjustment should be
made by a Yamaha dealer, since this
service requires special tools and tech-
nical skills. The specified settings are
listed below.
The spring preload setting is deter-
mined by measuring distance A, shown
in the illustration. The shorter the dis-
tance A is, the higher the spring pre-
load; the longer distance A is, the lower
the spring preload.

1. Distance A
Spring preload:
Minimum (soft):
Distance A = 216 mm (8.50 in)
Standard:
Distance A = 211.5 mm (8.33 in)
Maximum (hard):
Distance A = 206 mm (8.11 in)
Rebound damping force
To increase the rebound damping force
and thereby harden the rebound damp-
ing, turn the adjusting dial in direction
(a). To decrease the rebound damping
force and thereby soften the rebound
damping, turn the adjusting dial in di-
rection (b).
