1. Suspension fork setup

The suspension fork on your KUBERG Trial/Cross allows to adjust stiffness and damping. There’s an air valve on the upper side of the left leg of the fork, hidden under the cover, that enables to set air pressure (stiffness) accordingly to the rider’s weight and riding conditions. Recommended air pressure for the suspension fork is 50 - 100 psi (3.5 - 6.9 bar).

NOTE:
Push the handlebar down to spring the suspension fork before the air pressure setup.

WARNING!
Do not use air pressures above 100 psi (6.9 bar) or below 50 psi (3.5 bar), as it may damage the fork and render the motorcycle unstable, resulting in severe injury or death and/or damage to property.

For the best riding experience set the sag on the suspension fork:
Let the rider, dressed in full protective equipment, sit on the motorcycle with both hands on the handlebar and feet on the footpegs. The upper legs of the suspension fork should sag about 15 - 20% of travel, or around 0.25 - 0.35“ (7 - 9 mm).

The blue knob on the upper side of the right leg of the suspension fork allows to soften or harden damping. Turning the knob clockwise slows the suspension movement rate (increase damping) and counter-clockwise speeds up the suspension movement rate (decrease damping).

WARNING!
Do not set the damping of the suspension fork to its maximum while in off-road use, as it may render the motorcycle unstable, resulting in severe injury or death and/or damage to property.

2. Locked suspension fork

Follow these steps to check the rebound knob:

The blue knob should be seated tightly onto the fork and be able to do almost a half of a rotation. If it is rotating more than normal, the locking mechanism may fail to work properly and can disable the locking or conversely lock the suspension completely.

Required tools:

hex wrench #3

Take the sticker off the top of the blue knob.
Using the hex wrench #3 remove the cap. You will find a separate piece with a mechanism, that twists a component inside the rebound, including a rubber gasket.
Check all the parts for any visible damage, mud or debris and clean it properly before assembly.
Make sure, that the rebound housing is securely attached to the fork leg. If this is loose, it can also cause issues with the rebound.
Try to rotate the mechanism and decrease and increase the rebound just using a plier.
Reinstall the blue knob with its nut and using the hex wrech #3 tighten it (2-3 Nm).
