tic.
Extreme modifications to the suspension setting may cause a serious deterioration in the handling char-
acteristic and overload components.
–
Only make adjustments within the recommended range.

However, if the fork frequently bottoms out (hard end stop on
compression), the fork air pressure must be increased, within
the specified values, to avoid damage to the fork and frame.
–
If the fork feels unusually hard after extended periods of oper-
ation, the fork legs need to be bled.
