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.NOTE: 
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.

CAUTION:
 
ECB00090  
Never turn an adjusting mechanism beyond 
the minimum and maximum settings.NOTE:
 
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. 
1.  Compression damping force adjusting knob

Minimum (soft):
1 click(s) in direction (a)*
Standard:
11 click(s) in direction (a)*
Maximum (hard):

EBU24920 
Checking and lubricating the brake and 
clutch levers  
The operation of the brake and clutch levers
should be checked before each ride, and the lever
pivots should be lubricated if necessary. 
EBU24930 
Checking and lubricating the brake and 
shift pedals  
The operation of the brake and shift pedals should
be checked before each ride, and the pedal pivots
should be lubricated if necessary. 
EBU24961 
Checking the wheel bearings  
The front and rear wheel bearings must be
checked at the intervals specified in the periodic
maintenance and lubrication chart. If there is playin a wheel hub or if a wheel does not turn smoothly,
have a Yamaha dealer check the wheel bearings. 
EBU25001 
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:
Lithium-soap-based grease (all-purpose 
grease)
Recommended lubricant:
Lithium-soap-based grease (all-purpose 
grease)
Recommended lubricant:
Lithium-soap-based grease
