Adjusting The Shock Absorber Assembly - Yamaha 2011 WR250RA Owner's Manual

INSTRUMENT AND CONTROL FUNCTIONS
Adjusting the shock absorber
assembly
This shock absorber assembly is
1 equipped with a spring preload adjust-
ing ring, a rebound damping force ad-
justing knob and a compression
2
damping force adjusting screw.

NOTICE
To avoid damaging the mechanism,
do not attempt to turn beyond the
4
maximum or minimum settings.

Spring preload
Spring preload adjustment should be
6
made by a Yamaha dealer, since this
service requires special tools and tech-
7
nical skills. The specified settings are
listed below.
The spring preload setting is deter-
8
mined by measuring distance A, shown
in the illustration. The shorter the dis-
9
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 = 216.0 mm (8.50 in)
Standard:
Distance A = 211.5 mm (8.33 in)
Maximum (hard):
Distance A = 206.0 mm (8.11 in)
Rebound damping force
To increase the rebound damping force
and thereby harden the rebound damp-
ing, turn the adjusting knob in direction
(a). To decrease the rebound damping
force and thereby soften the rebound
damping, turn the adjusting knob in di-
rection (b).

Standard:
Maximum (hard):
* With the adjusting knob fully turned in
direction (a)
Compression damping force
To increase the compression damping
force and thereby harden the compres-
sion damping, turn the adjusting screw
in direction (a). To decrease the com-
pression damping force and thereby
soften the compression damping, turn
the adjusting screw in direction (b).
