WARNING
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.
TIP
A special wrench can be obtained at a
Yamaha dealer.

The spring preload can be adjusted by turn-
ing the adjusting rings.
To increase the spring preload and thereby
harden the suspension, turn the adjusting
ring in direction (a). To decrease the spring
preload and thereby soften the suspension,
turn the adjusting ring in direction (b).
