To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.
For YZF-R1:
This model is equipped with adjustable
suspension. The spring preload, re-
bound damping force, fast compres-
sion damping force, and slow
compression damping force can be ad-
justed.
Spring preload
1. Loosen the locknut.
2. To increase the spring preload and
thereby harden the suspension,
turn the adjusting ring in direction
(a). To decrease the spring pre-
load and thereby soften the sus-
pension, turn the adjusting ring in
direction (b).
The spring preload setting is deter-
mined by measuring distance A.
The longer distance A is, the high-
er the spring preload; the shorter
distance A is, the lower the spring
preload.
Use the special wrench includ-
ed in the owner’s tool kit to
make the adjustment.
3. Tighten the locknut to the specified
torque.
NOTICE:
Always tighten
the locknut against the adjust-
ing ring, and then tighten the
locknut to the specified
torque.

Rebound damping force
To increase the rebound damping force
and thereby harden the rebound damp-
ing, turn the adjusting screw in direction
(a). To decrease the rebound damping
force and thereby soften the rebound
damping, turn the adjusting screw in di-
rection (b).
