Alpinestars BNS Tech 2 Neck Support Review 2026

Neck injuries represent some of the most severe and potentially life-altering outcomes in motocross and off-road crashes. The Bionic Neck Support concept exists to provide a mechanical means of managing the impact forces that in a crash would otherwise be transmitted directly to the cervical spine, and the BNS Tech 2 represents the mature development of that concept with the engineering specification and CE certification that gives it formal safety credibility.

The BNS Tech 2 is constructed from an advanced, high-performance carbon polymer compound. The material choice is significant: carbon polymer provides the structural rigidity needed to resist and redirect impact forces while keeping the weight of the device as low as possible for wearing comfort during riding. The weight reduction compared to earlier BNS generations is delivered without compromise on strength or structural integrity — the material maintains its performance properties even below 0°C, addressing the cold-weather riding conditions where material degradation can affect protection reliability.

The defining feature of the BNS is its mode of operation. When a crash occurs and the rider’s helmet makes contact with the BNS frame, the device provides a clean, solid surface that instantly channels the compressive and rotational impact energy away from the neck and on to the BNS structure. The rear stabiliser — developed using Alpinestars’ exclusive Progressive Force Relief (PFR) technology — transmits this energy across the back and shoulders through a pivot-key connection, progressively distributing the energy loads rather than transmitting them as a single peak force. The frame construction is also designed to prevent hyper-flexion through its raised chest section and rear support edge that fits close to the body.

The quick-release locking system allows rapid, efficient fitting and removal of the BNS without requiring the complex adjustment that earlier neck support devices demanded. The SAS (Size Adapter System) provides a versatile fitment across size ranges XS-M and L-XL using interchangeable EVA foam pads, and the Lycra-laminated foam padding kits are adaptable to allow compatibility with different body protection systems.

Who is the Alpinestars BNS Tech 2 Neck Support aimed at?

The BNS Tech 2 is for serious MX, enduro, and off-road riders who compete or ride at a level where neck protection forms part of their safety kit, and who want CE certified neck protection with engineering pedigree. BNS-compatible chest protectors (A-1 Pro, A-10 V2, and others with BNS pull tabs) should be used alongside the device for the integrated protection system to function correctly.
