  • Shell construction utilizes a highly advanced molding technology with a multi-composite combination
  • Uni-Directional carbon composite layer that gives significantly greater radial strength around the shell, preventing compression but allowing controlled deflection for reducing transmitted impact energy
  • 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 EPS (Expanded Polystyrene) liner
  • Multi-Directional Impact Protection System (MIPS)
  • MIPS is incorporated to reduce rotational motion energies that impact the helmet causing damage gyration force to be transmitted to the brain
  • A low friction slip layer is incorporated into the helmet, between the comfort padding layer and the multi-density polymer energy absorption shell
  • When energy is impacted upon the helmet, causing a rotation force, the MIPS layer allows for movement of the inner absorption layer to damp and re-direct the energy before causing significant accelerations stress to the brain
  • Four anatomical shell sizes
  • Liner construction combines with shell to offer highly efficient impact energy management
  • 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
  • Heat mapping tests have resulted in specifically designed ducting which produces a positive flow into the helmet over and around the rider's head, improving comfort while riding and reducing the on-set of heat stress in extreme conditions
  • Interior lining comfort
  • Removable liner cover is washable and features a CoolMax fabric interior and anti-bacterial talent yarn for long lasting freshness and quick dry performance between riding sessions
  • ERS (Emergency Release System)
  • The side cheek padding 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 or medical staff
  • Along with the ERS padding removal, Eject feature allows for emergency removal of the helmet, without putting load on the rider's spine
  • 26mm chinstrap for comfort and produced with woven poly yarn to give soft hand feel that connects securely with a double D-Ring
  • Patented A-Head fitting height and angle adjustment system allows helmet to be tuned exactly to the riders preference
  • 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
  • Unique, patented visor release system which, while ensuring the mounting is held securely in place for riding over the most extreme terrain and any track conditions, provides exactly the right level of resistance to ensure the visor detaches from the helmet shell should it be subjected to impact no matter the angle
  • Maintaining shell integrity is vital for safety and with the possibility of multi-directional forces impacting on the visor, separation at the critical point of loading reduces potentially damaging leverage and rotational accelerations that refer injury to the riders neck and spine
  • The base of the S-M8 has been sculpted to give a relief section, where the bottom profile is raised to clear the collarbone
  • Also, incorporated into the area if the base pad, where it sits over the rider's collarbone, is an energy absorbing pad
  • Chin-bar is formed with polypropylene which, by allowing for a degree of lateral deflection, further improves impact protection for the collarbones
  • TPE coating washable surfaces to improve maintenance and increase durability
  • Hydration system compatible
  • Includes soft helmet bag
  • Meets or exceeds DOT and ECE certifications
