EBU35660Flag pole bracketThis model is equipped with a flag pole brack-
et.NOTICEECB03010Do not use the flag pole bracket as a cargo
hook. EBU40060Front shock absorbersThe shock absorber assemblies are equipped
with the following adjusters.
Spring preload adjusting nut
 Rebound damping force adjusting screw
 High speed compression damping force
adjusting bolt
 Low speed compression damping force
adjusting screw
 Crossover adjusting nut
WARNING
EWB04140Suspension components become hot
during operation. Never touch the com-
pression damping force adjusting bolt
and screw, the rebound damping force
adjusting bolt and screw, or the oil reser-
voir 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.

Notes on adjusting the suspension
A special wrench and special tool can be
obtained at a Yamaha dealer to make the
spring preload or crossover setting adjust-
ment.
 When adjusting the damping force settings,
turn the adjuster in direction (a) until it
stops, and then count the turns or clicks in
direction (b).
 Although a damping force adjuster may
turn or click beyond the stated minimum
settings, such adjustments are ineffective
and may damage the suspension.NOTICEECB00091Never turn an adjusting mechanism be-
yond the minimum and maximum settings. Spring preload
1. 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.

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. EBU40070Rear shock absorbersThe shock absorber assemblies are equipped
with the following adjusters.

TIPThe 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. 1. Locknut
