CONSTRUCTION

  • Shell construction utilizes a highly advanced molding technology with a multi-composite combination: uni-directional carbon composite with aramid layer that gives significant radial strength around the shell, preventing compression but allowing controlled deflection for reducing transmitted impact energy, and providing critical penetration protection.
  • This combination of layers is given even greater performance with an epoxy resin bonding that offers the best possible strength and energy management; limited outer shell deflection means the energy spreads wider and is better absorbed by the EPS liner.
  • The result of the unique shell lay-up process employed in the S-M8 construction results in extremely effective impact protection. With a fully equipped helmet testing facility, within Alpinestars Racing Development Center, an exhaustive impact research program has resulted in the Supertech M8 returning linear and oblique impact performance which far improves upon current helmet regulation standard limits. For direct, linear, impact by an average magnitude of 41% and for rotational acceleration, oblique, impact performance by an average of 48%.
  • The Supertech M8 liner construction combines with the shell to offer highly efficient impact energy management.
  • The Supertech M8 liner construction combines with the shell to offer highly efficient impact energy management.
  • Formed with a multi-density EPS polymer, the energy absorbing layer gives an inner helmet profile which soaks up impact forces dissipated over the outer shell at the point of an impact and provides a shape offering a close and comfortable fit.
  • The energy absorption performance of the S-M8 is substantially improved by a four section construction that allows for specific densities of polymer to be prepared for different zones around the helmet lining. Not only is energy performance improved but also fit and comfort.
  • Patented A-Head fitting height and angle adjustment system.
  • With a micro-adjustable pad that is connected to the helmet inner shell, it is possible to raise or lower the helmet fit and also, to tilt the helmet forward, or backwards.

PROTECTION

  • Collarbone protection is an important design feature of the Supertech M8 helmet shell base profile.
  • The base of the S-M8 has been sculpted to give a relief section, where the bottom profile is raised to clear the collarbone (Clavicle). Also, incorporated into the area of the base pad, where it sits over the rider’s collarbone, is an energy absorption pad; a more flexible compound rubber section which allows deflection when it contacts the Clavicle.
  • The Supertech M8 chin-bar is formed with polypropylene which, by allowing for a degree of lateral deflection, further improves impact protection for the collarbones.
  • Post-crash protection mechanisms are also a key feature of the Supertech M8 design, allowing rapid and safe intervention if the rider has suffered a major impact.
  • Multi-Directional Impact Protection System: MIPS.
  • MIPS is incorporated into the Supertech M8 to reduce rotational motion energies that impact the helmet causing damaging gyration force to be transmitted to the brain.
  • Emergency Release System (ERS).
  • The side cheek padding of the S-M8 can be extracted efficiently and safely, while the helmet is still on the rider’s head, to allow ease of removal by trackside support and medical staff.
  • The Supertech M8 is also designed to allow a helmet ‘Eject’ inflation system to be fitted into the inside crown of the shell.
  • Along with the ERS padding removal, ‘Eject’ allows for emergency removal of the helmet, without putting load on the rider’s spine.
  • Chin-strap: Wider than certification requirement: 26 mm for comfort and produced with a woven poly yarn to give a soft ‘hand’ feel that connects securely with a double D-ring.
  • Weight: Reduced by design while allowing the Supertech M8 protection to be class-leading.
  • Weight is both a factor in riding performance and safety in a helmet and to ensure the S-M8 offers the ultimate in weight saving performance enhancement, the material selection, preparation and construction of the helmet has been rigorously analyzed for weight to strength and energy absorption properties and a strict analysis of all the components used in the Supertech M8 finishing.
  • Weight of S-M8 is 1300g for size Medium (ECE) - 1360g for size Medium (DOT)
  • The Supertech M8 Certifications.
  • The Supertech M8 helmet versions conform to both DOT certification and ECE homologation for use worldwide.
  • The DOT 218 standard prescribes specific impact penetration protection over the crown of the helmet area and hence, for the US and Canada markets, the Supertech M8 will feature technology that substantially exceeds the minimum safety requirements.
