adjusting mechanism. This adjustment
range may not exactly match the spec-
ifications listed due to small differences
in production.
For YZF-R1M:
This model is is equipped with ÖHLINS
electronic racing suspension.
Compression damping force and
rebound damping force
The compression and rebound damp-
ing forces are electronically controlled
and can be adjusted from the MENU
screen. See ERS on page 4-18 for in-
formation on how to adjust these set-
tings.
Spring preload
The spring preload adjustment is per-
formed manually.
NOTICE
ECA10102
To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.
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 in the
owner’s tool kit to make the ad-
justment.
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.
