WARNING
EWB00401
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.
NOTICE
ECB01091
Never turn the adjusting mechanism beyond
the minimum and maximum settings.
Adjust the spring preload as follows.
Turn the spring preload adjusting ring in direction
(a) to increase the spring preload and thereby
harden the suspension, and in direction (b) to de-
crease the spring preload and thereby soften the
suspension.
Align the appropriate notch in the adjusting ring
with the position indicator on the shock absorber.
TIP
A special wrench can be obtained at a Yamaha
dealer to make this adjustment.
