Compression damping force (for slow com-pression damping)To increase the compression damping force
and thereby harden the compression damp-
ing, turn the compression damping force ad-
justing screw in direction (a). To decrease the
compression damping force and thereby
soften the compression damping, turn the
adjusting screw in direction (b).
WARNING
EWB00411These shock absorber assemblies contain
highly pressurized nitrogen gas. Read and
understand the following information be-
fore handling the shock absorber assem-
blies.
 Do not tamper with or attempt to open
the cylinder assemblies.
 Do not subject the shock absorber as-
semblies to an open flame or other high
heat source. This may cause the unit to
explode due to excessive gas pressure.

Do not deform or damage the cylinders
in any way. Cylinder damage will result in
poor damping performance.
 Do not dispose of a damaged or worn
out shock absorber assembly yourself.
Take the shock absorber assembly to a
Yamaha dealer for any service. EBU33620Adjusting the rear shock absorber as-
sembliesThese shock absorber assemblies are
equipped with a spring preload adjusting nut,
a rebound damping force adjusting screw, a
compression damping force adjusting bolt
(for fast compression damping), and a com-
pression damping force adjusting screw (for
slow compression damping).
WARNING
EWB02492 Suspension components become hot
during operation. Never touch the com-
pression damping force adjusting bolt and screw, the rebound damping force
adjusting screw or the oil reservoir with
your bare hand or skin until suspension
components have cooled.
 Always adjust the shock absorber as-
semblies on the left and right side to the
same setting. Uneven adjustment can
cause poor handling and loss of stability,
which could lead to an accident.
NOTICEECB00091Never turn an adjusting mechanism be-
yond the minimum and maximum settings. TIPAlthough the total number of clicks or turns of
a damping force adjusting mechanism may
not exactly match the following specifications
due to small differences in production, the ac-
tual number of clicks or turns always repre-
sents the entire adjusting range. To obtain a
precise adjustment, it would be advisable to

check the number of clicks or turns of each
damping force adjusting mechanism and to
modify the specifications as necessary. Spring preload1. Loosen the locknut.
2. Turn the spring preload adjusting nut in direction (a) to increase the spring pre-
load and thereby harden the suspension,
and in direction (b) to decrease the spring
preload and thereby soften the suspen-
sion.
TIPA special wrench can be obtained at a
Yamaha dealer to make this adjustment.
 The spring preload setting is determined by
measuring distance A, shown in the illustra-
tion. The shorter distance A is, the higher
the spring preload; the longer distance A is,
the lower the spring preload. With each
complete turn of the adjusting nut, distance
A is changed by 1.5 mm (0.06 in). 1. Locknut

3. Tighten the locknut to the specifiedtorque. NOTICE: Always tighten the
locknut against the adjusting nut, and
then tighten it to the specified torque.

Rebound damping force
Turn the rebound damping force adjusting
screw in direction (a) to increase the rebound
damping force and thereby harden the damp-
ing, and in direction (b) to decrease the re-
bound damping force and thereby soften the
damping.
Spring preload setting: Minimum (soft):Distance A = 386.0 mm (15.20 in)
Standard: Distance A = 378.0 mm (14.88 in)
