Alpinestars Supertech M8 Echo MIPS Adult Off-Road Helmets

At the outset of the MX helmet project, Alpinestars product philosophy was applied and a set of specific objectives set: Create the most advanced, protective and performance enhancing helmet possible. Primary objective: protection – to create the most high performance protection possible. Secondary objective: to give excellent ventilation, comfort and reduced weight.

Alpinestars approach to the creation of the advanced technology in the Supertech M8 draws on its depth of experience from over half a decade of world class innovation across the spectrum of motorsports and especially, its deep rooted commitment to motocross. As with all other categories of technology that Alpinestars has mastered, bringing a new, highly complex, product to fruition requires specialist experience and know-how and a project plan led by the best brains in protection development.

Hence Alpinestars Helmet Development Department was created and given the brief to research and develop the most protective and most comfortable possible motocross helmet. The goal was to allow riders to push the limits of performance, benefiting from confidence inspiring safety technology, reduced weight distribution to minimise muscular effort in the neck, shoulders and back and improved physiological and cognitive performance with a supremely well fitting and well ventilated construction, optimizing comfort while riding.

The design is coherent to Alpinestars philosophy and shares distinctive themes with other products in the portfolio; a smooth, attractive, profile which is streamlined and free of any external channels and features that might act as a load point in an impact, or compromise the overall integrity of the construction. The surface curvature promotes reduced friction on impact, allowing deflection and the most efficient transfer of energy to protect the rider's head from direct force to the skull and referred to the neck and spinal column. The aperture is designed to accommodate a wide variety of goggles and the air vents in the shell are located to maximize ventilation efficiency.

The S-M8 shell has been profiled with performance as a priority and with a design style that identifies the profile of the helmet and its sculpted surface as uniquely 'Alpinestars'.

Another key feature is the S-M8 shell sizing solution; each helmet fit size has its own appropriate shell size to deliver the most anatomical solution for the wide variety of fit needs worldwide.

  • Lightweight outer shell is constructed from technologically advanced composite materials for best fit
  • Multiple density inner liner
  • Fitted with E-2, latest generation of MIPS, integrated low-friction layer designed to reduce rotational motion transferred to the brain from angled impacts to the head
  • Visor attached to the helmet shell with patented system that will allow easy release in case of crash
  • Adjustable top pad height (Alpinestar's patented A-Head system)
  • Maximized ventilation with 19 intakes and 5 exhaust ports
  • Side shell shape coupled with soft EPP foam prevents damage to collarbone in event of crash
  • Emergency release and removable cheek pads, 3D contoured foam
  • Removable comfort liner, anti-moisture and anti-bacterial fabrics
  • Hydration prepared
