Smaller differences in the rider's weight can be compen-
sated for by the fork air pressure.
–
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.
(50 SX Mini)
–
As with the shock absorber, smaller differences in the rid-
er's weight can be compensated by the spring preload.
–
However, if the fork frequently bottoms out (hard end stop
on compression), harder springs must be fitted to avoid
damage to the fork and frame.

tic.

Make sure your child rides slowly to start with after making adjustments in order that he or she can
