EBU35660Flag pole bracketThis model is equipped with a flag pole brack-
et.NOTICEECB03010Do not use the flag pole bracket as a cargo
hook.
EBU35035Front shock absorbersThe shock absorber assemblies are equipped
with a spring preload adjusting nut, a rebound
damping force adjusting screw, a fast com-
pression damping force adjusting bolt, and a
slow compression damping force adjusting
screw.
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. Elevate the vehicle and place a suitable
stand under the frame.
2. Loosen the locknut. 3. 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.1. Locknut

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.
EBU35045Rear shock absorbersThe rear shock absorber assemblies are
equipped with a spring preload adjusting nut,
a rebound damping force adjusting screw, a
fast compression damping force adjusting
bolt, and a slow compression damping force
adjusting screw.
WARNING
EWB02492 Suspension components become hot
during operation. Never touch the com-
pression damping force adjusting bolt
and screw, the rebound damping force
Slow compression damping force settings:
Minimum (soft):4 turn(s) out from the fully turned in posi-
tion
Standard: 2 turn(s) out from the fully turned in posi-
tion
Maximum (hard): Adjusting screw fully turned in
