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. 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.
The Alpinestars S-M8 Radium 2 Helmet combines advanced motocross protection technology with a profile developed for performance. Its sculpted shell design reflects Alpinestars’ motorsports experience while providing an anatomical fit approach for a wide range of riders. Each helmet fit size uses an appropriate shell size to support a more precise fit solution.
The helmet features a multi-density EPS polymer liner, Multi-directional Impact Protection System (MIPS), and a patented A-Head fitting height and angle adjustment system.
