Adjusting the front shock absorber
assemblies
The spring preload can be adjusted to suit the rid-
er’s weight and the riding conditions.
Adjust the spring preload as follows.
Turn the adjusting ring in direction (a) to increase
the spring preload and thereby harden the suspen-
sion, and in direction (b) to decrease the spring
preload and thereby soften the suspension.
TIP
A special wrench can be obtained at a Yamaha
dealer to make this adjustment.

WARNING
EWB00400
Always adjust the shock absorber assemblies
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 ac-
cident.
EBU19100
Adjusting the rear shock absorber
assembly
The spring preload, rebound damping and com-
pression damping forces of the rear shock absorb-
er assembly can be adjusted to suit the rider’s
weight and the riding conditions.
WARNING
EWB00430
This shock absorber assembly contains highly
pressurized nitrogen gas. Read and under-
stand the following information before han-
dling the shock absorber assembly.
Do not tamper with or attempt to open the
cylinder assembly.
Do not subject the shock absorber assembly
to an open flame or other high heat source.
This may cause the unit to explode due to ex-cessive gas pressure.
Do not deform or damage the cylinder 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 deal-
er for any service.
Spring preload
1. Loosen the locknut.
2. Turn the adjusting nut in direction (a) to in-
crease the spring preload and thereby harden
the suspension, and in direction (b) to de-
crease the spring preload and thereby soften
the suspension.

NOTICE
ECB00090
Never turn an adjusting mechanism beyond
the minimum and maximum settings.
TIP
Although the total number of clicks of a damping
force adjusting mechanism may not exactly match
the above specifications due to small differences in
production, the actual number of clicks always rep-
resents the entire adjusting range. To obtain a pre-
cise adjustment, it would be advisable to check the
number of clicks of each damping force adjusting
mechanism and to modify the specifications as
necessary.WARNING
EWB00460
Suspension components become hot during
operation. Never touch the compression
damping force adjusting knob, the rebound
damping force adjusting dial or the oil reser-
voir with your bare hand or skin until suspen-
sion components have cooled.

Minimum (soft):

Checking the wheel hub bearings
The front and rear wheel hub bearings must be
checked at the intervals specified in the periodic
maintenance and lubrication chart. If there is play
in a wheel hub or if a wheel does not turn smoothly,
have a Yamaha dealer check the wheel hub bear-
ings.
EBU25003
Lubricating the rear suspension relay
arm and connecting arm pivoting
points
The rear suspension relay arm and connecting
arm pivoting points must be lubricated at the inter-
vals specified in the periodic maintenance and lu-
brication chart.
Lubricate the pivoting points using a grease gun.Recommended lubricant:
Silicone grease
Recommended lubricant:
Lithium-soap-based grease
