 The Alpinestars Bionic Neck Support is designed to help prevent injury in a crash situation by dissipating and diverting impact forces away from the neck and spine. When the dirt bike rider's helmet makes contact with the frame at the moment of a crash, the neck brace provides a clean, solid surface which instantly channels damaging, compressive impact energy away from the neck. Primarily for use in motocross and offroad riding this protection device offers a highly personalized and stable fit while being lightweight and strong.

  • Offroad neck brace constructed from an advanced high performance fiberglass polymer resin to offer structural integrity and frame strength against heavy impact energies during crashes
  • Incorporates a bio-organic engineering design for superb ergonomics
  • Frame construction promotes improved contact with helmet during impact and instantaneous load channeling
  • Rear support edge fits closer to the body, while the extra frame width accounts for different helmet sizes, and raised chest reduces hyperflexion injuries
  • Rear stabilizer promotes PFR (Progressive Force Relief) and dissipates energy loads by transmitting them across the back and shoulders and away from spine (thoracic vertebrae), and is connected to the frames via pivot key for convenient dismantling
  • Compressed EVA (Ethylene Vinyl Acetate) foam compound padding to distribute the impact force over the widest area, yet remain lightweight
  • Lycra laminated foam padding for an adaptable and interchangeable compatibility with body protection systems
  • SAS (Size Adapter System) for a versatile fitment covering multiple size ranges
  • Innovative quick release locking closure system for rapid and efficient fitting/removal offers a highly secure and convenient attachment
  • Strap system includes a light strap to be worn over or under the jersey
  • Designed to provide a customizable, secure, and personalized fit
  • Lightweight performance and comfort while riding
  • Resilience to low temperatures, below 0°C
  • Black/White/Red
