TIP

Although the total number of clicks
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
adjusting bolt in direction (a), the 0
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.

ing forces are electronically adjusted.
