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.

FAQs
The BNS Tech 2 works by creating a solid contact surface between your helmet and the frame during impact. When your helmet makes contact with the support in a crash, the carbon polymer compound instantly dissipates and diverts compressive forces away from your neck and spine, channeling them through the BNS structure instead. This reduces the load transferred to vulnerable cervical vertebrae.
The PFR rear stabilizer is Alpinestars' exclusive technology that provides graduated energy absorption during impact. Rather than creating a hard stop, it allows controlled, progressive displacement under extreme loads, which helps manage forces more effectively across different crash scenarios. This system enhances the overall protective performance while maintaining rider comfort during normal riding.
Yes, the BNS Tech 2 is specifically designed for motocross and off-road riding. It features a quick release locking system for easy fitting with MX jerseys and body armor. The carbon polymer construction is lightweight enough for extended riding sessions while maintaining structural integrity. For optimal fit, ensure your chest protector and jersey accommodate neck support systems.
Proper fit is achieved when the BNS sits flat on your upper back and collarbone area without restricting head movement during normal riding. The rear stabilizer should rest comfortably against your upper spine, and the front should allow your helmet to make clean contact with the frame during forward motion. Consult the sizing guide for specific measurements based on your torso dimensions and riding position.
The BNS Tech 2 is optimized specifically for motocross and off-road riding due to its geometry and force management characteristics designed for these disciplines. While the protective principles apply universally, the fit and performance are calibrated for MX body positioning and impact vectors. For other riding styles, Alpinestars offers discipline-specific neck protection solutions.
