TIP
Although the total number of clicks of a
damping force adjusting mechanism
may not exactly match the above spec-
ifications due to small differences in
production, the actual number of clicks
always represents the entire adjusting
range. To obtain a precise adjustment,
it would be advisable to check the num-
ber of clicks of each damping force ad-
justing mechanism and to modify the
(b)
specifications as necessary.
For YZF-R1M:
This model is is equipped with ÖHLINS
electronic racing suspension.
The compression and rebound damp-
ing forces are electronically adjusted.
(See ERS on page 5-19.)
Spring preload
The spring preload adjustment is per-
formed manually.
1. Turn the vehicle off.
2. Slide the rubber cover back at
each coupler.
3. Remove the coupler on each front

4. To increase the spring preload and
thereby harden the suspension,
turn the adjusting bolt on each fork
leg in direction (a). To decrease
the spring preload and thereby
soften the suspension, turn the ad-
justing bolt on each fork leg in di-
rection (b).
