Adjusting the shock absorber
assembly
WARNING
EWA10222
This shock absorber assembly con-
tains highly pressurized nitrogen
gas. Read and understand the fol-
lowing information before handling
the shock absorber assembly.
Do not tamper with or attempt to
open the cylinder assembly.
Do not subject the shock ab-
sorber assembly to an open
flame or other high heat source.
This may cause the unit to ex-
plode due to excessive gas
pressure.
Do not deform or damage the
cylinder in any way. Cylinder
damage will result in poor
damping performance.
Do not dispose of a damaged or
worn-out shock absorber as-
sembly yourself. Take the shock
absorber assembly to a Yamaha
dealer for any service.
NOTICE
ECA10102
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.
