The Alpinestars Bionic Neck Support (BNS) is a structure which is designed to work with a helmet to reduce the risk and severity of a catastrophic neck injury (i.e. A paralyzing injury).

While no product can guarantee protection from all motorcycle injuries, due to the varied dynamics of accidents, the BNS is designed to substantially reduce the likelihood of a career ending neck injury although it must be stated at the outset that it, as with other such systems, may not prevent injuries occurring in all cases.

The BNS functions by providing an alternative load path for the energy that compresses the neck. If the helmet is in contact with the Bionic Neck Support at the moment of impact the overall load passing through the neck can be reduced, which may prevent a fracture from occurring.

The BNS also helps reduce the chance of muscular injuries associated with extremes of head movement.
