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.
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.
As with any riding equipment, fit is critical to ensuring the most
effective protection possible and riders should choose the equipment
that is best suited to their body. No neck device should roll around
over the shoulders.
Bionic Neck Support Selection and Fitting
The table below provides a guide to the fitting process. Find your corresponding jacket size in the left columns of the table, compare to your chest circumference measurement, and then select a size of Bionic Neck Support frame on the right depending on how thick or thin (T) your chest is.
