LS2 Advant II FF910 Astral Chin Lock Mechanism - Replace the original opening/closing system

When the adjustable tone mechanism tires, the whole riding experience takes a hit. With the LS2 Advant II FF910 Astral locking mechanism, your helmet regains smooth opening, reliable locking and all the comfort of the first day.

The Advant II FF910 Astral chinstrap locking mechanism is an official LS2 spare part, designed to restore the chinstrap articulation and locking system on the FF910 flip-up helmet in its Astral color.

With time, impact or natural wear, the mechanism can lose fluidity, precision or safety. This part allows you to regain perfect operation: smoother opening, secure locking and a return to the helmet's original behavior.

This original LS2 mechanism mounts directly onto the chinstrap of the FF910 Astral, without adaptation. The attachment points are identical, the kinematics are calibrated exactly like those on the new helmet, and the mechanism is compatible with all existing components (chinstrap, shell, vents).

An essential part if you want to keep your helmet in perfect condition and enjoy your flip-up helmet for a long time to come.

Frequently asked questions

Is this mechanism compatible with other FF910 colors?
No, this version is specific to theAstral, notably for the compatibility of certain associated parts.

Is installation complicated?
It requires a minimum of precision, as it's a mechanical element. You can do it yourself if you're comfortable, otherwise a professional can install it in a few minutes.

Do I have to replace both sides of the mechanism?
If your helmet shows wear on only one side, a single replacement is sufficient. In the case of symmetrical wear, replacing both sides may be a good idea.
