The Bionic Neck Support Tech 2 is constructed from an advanced, high-performance carbon polymer compound and is designed to help prevent injury in a crash situation by dissipating and diverting impact forces away from the neck and spine. The BNS functions when the rider*s helmet makes contact with the frame at the moment of a crash, thus providing a clean, solid surface which instantly channels damaging, compressive impact energy away from the neck and on to the BNS. Featuring Alpinestars* exclusive and revolutionary rear stabilizer for progressive force relief (PFR) the BNS Tech 2 is designed for use in motocross and off-road riding and offers a highly personalized and stable fit while incorporating innovative new features such as a new quick release locking system.
