Spring preload
1. Loosen the locknut.
2. Turn the spring preload adjusting nut in
direction a to increase the spring pre-
load and thereby harden the suspension,
and in direction b to decrease the spring
preload and thereby soften the suspen-
sion.

TIP
●
A special wrench can be obtained at a
Yamaha dealer to make this adjustment.
●
The spring preload setting is determined
by measuring distance A, shown in the il-
lustration. The shorter distance A is, the
lower the spring preload; the longer dis-
tance A is, the higher the spring preload.
With each complete turn of the adjusting
nut, distance A is changed by 1.5 mm
(0.06 in).
