
To avoid damaging the suspen-
sion's internal mechanisms, do
not attempt to turn beyond the
maximum or minimum settings.
For YZF-R1:
This model is equipped with adjustable
suspension. The spring preload, re-
bound damping force, and compres-
sion damping force of each leg can be
adjusted.
WARNING
Always adjust both fork legs equal-
ly, otherwise poor handling and loss
of stability may result.
Spring preload
To increase the spring preload and
thereby harden the suspension, turn
