The fork triple clamps must be made withhigh accuracy and the fork leg mounts mustbe in an absolute straight line not to cause malfunctions.
Suspension ﬂuid level diagram
The diagram below shows reaction forcecurves at two diﬀerent ﬂuid levels. A change in the ﬂuid level will mainly aﬀect the air spring force and rate at the end of the front fork travel.
High ﬂuid level
The air spring in the later half stage of travel is stronger which makes the front fork ﬁrmer.
Low ﬂuid level
The air spring in the later half stage of travelis lessened which makes the front fork more linear.
Adjust suspension ﬂuid level.
