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 riding motocross or off-road.
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 comes with its own carrying bag for extra convenience.
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
While it is not possible to eliminate the risk of any form of injury, the BNS is designed to help prevent the most serious damage and minimize the risk of collateral injury as the impact load is channeled away from the neck
When compared to soft ‘neck roll’ devices the protection afforded is significantly better because being soft, these devices simply deform, offering no protection against the damaging compressive forces
A special magnesium key located at the rear allows the convenient front opening of the device while also allowing it to be dismantled in an emergency
Fitting System: Fine adjustment of the shoulder height allows a more personalized fit., particularly for individuals who have a shorter than normal neck
Rear Stabilizer Failure system: In the event of large loads being channeled onto the rear stabilizer (the part that sits on the back) there are a number of deliberate bending and fracture points
