Bos Dizzy 2014 User manual - Manual (Page 7)

The S position is for comfort.
The H position is used for pedaling efficiency.
The H position considerably stiffens the fork in an effort to limit suspension oscillations during pedaling, but without locking out
the fork completely. Thus, BOS remains faithful to the principle of keeping an active fork, even in its restrained state. This allows
for the suspension to move over unexpected bumps, which is a simple matter of security.
The M position maintains hydraulic control and grip.
The M position in the middle is set at a precise position at the factory. However, the final user maintains the possibility
of adjusting the firmness between the S and H poles. In effect, M is the base position that offers the best compromise between
comfort, chassis support, and grip. If the rider prefers a softer feeling or a harder feeling, he may change the position toward the
open or closed positions, S and H, without affecting the tuning of the fork.
