TIP

Although the total number of clicks
12
of a damping force adjusting
mechanism may not exactly match
the above specifications due to
small differences in production, the
actual number of clicks always
represents the entire adjusting
range. To obtain a precise adjust-
ment, check the number of clicks
and modify the minimum and stan-
dard specifications as necessary.

When turning the damping force
1 adjusting bolt in direction (a), the 0
(b)
click position and the 1 click posi-
tion may be the same.
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 4-19 for in-
formation on how to adjust these set-
tings.
Spring preload
The spring preload adjustment is per-
formed manually.
NOTICE
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.
