WARNING
EWS00151
Read and understand the following infor-
mation before handling shock absorbers
that contain highly pressurized nitrogen
gas.
● Do not tamper with or attempt to open
the cylinder assemblies.
● Do not subject the shock absorbers 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 yourself. Take the
shock absorber to a Yamaha dealer for
any service.

Adjusting the spring preload of the
front shock absorbers
WARNING
EWS00720
The spring preload of the left and right
shock absorbers must be adjusted to the
same setting. Uneven settings can cause
poor handling and loss of stability.
The spring preload can be adjusted by turning
the adjusting nuts.
Adjust the spring preload as follows.
1. Loosen the locknut.
2. To increase the spring preload and there-
by harden the suspension, turn the ad-
justing nut in direction (a). To decrease
the spring preload and thereby soften the
suspension, turn the adjusting nut in di-
rection (b).
TIP
The spring preload setting is determined by
measuring distance A, shown in the illustra-
tion. The longer distance A is, the higher the
spring preload; the shorter distance A is, the
lower the spring preload.
3. Tighten the locknut to the specified
torque. NOTICE: Always tighten the
locknut against the adjusting nut, and
then tighten the locknut to the speci-
fied torque.
