TIPAlthough the total number of clicks of a damp-
ing force adjusting mechanism may not exact-
ly match the above specifications due to small
differences in production, the actual number
of clicks always represents the entire adjust-
ing range. To obtain a precise adjustment, it
would be advisable to check the number of
clicks of each damping force adjusting mech-
anism and to modify the specifications as nec-
essary.

WARNING
●
Suspension components become hot
during operation. Never touch the
compression damping force adjusting
screw, the rebound damping force ad-
justing screw or the oil reservoir with
your bare hand or skin until suspen-
sion 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 acci-
dent.
5UG1B002Adjusting the rear shock absorber
assemblies (YXR7FSPD)
WARNING
These 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 cylin-
ders in any way. Cylinder damage will
result in poor damping performance.
●
Do not dispose of a damaged or worn
out shock absorber assembly your-
self. Take the shock absorber assem-
bly to a Yamaha dealer for any
service.
The spring preload, rebound damping and
compression damping forces of the rear
shock absorber assemblies can be adjusted
to suit the operating conditions.NOTICENever turn an adjusting mechanism be-
yond the minimum and maximum settings.
Spring preload
1. 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.1. Locknut

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 il-
lustration. The shorter distance A is, the
lower the spring preload; the longer dis-
tance A is, the higher the spring preload.
With each complete turn of the adjusting
nut, distance A is changed by 1.5 mm
(0.06 in).

3. Tighten the locknut to the specifiedtorque.NOTICEAlways tighten the locknut against the ad-
justing nut, and then tighten it to the spec-

Standard: Distance A = 63.5 mm (2.50 in)
