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.\n\u003cp\u003eThe Alpinestars S-M8 Radium 2 Helmet combines advanced motocross protection technology with a performance-focused shell profile and distinctive Alpinestars styling. Developed from extensive experience across motorsports, the S-M8 is designed with a focus on anatomical fit, impact protection, and functional adjustability.\u003c\/p\u003e\u003cp\u003eThe helmet uses four anatomical shell sizes, with each fit size receiving an appropriately sized shell for a more precise fit solution. Its multi-density EPS polymer liner supports the helmet’s protective design, while the patented A-Head system provides fitting height and angle adjustment. The shell base also incorporates a collarbone protection feature.\u003c\/p\u003e\u003cp\u003eAdditional safety and usability features include the Multi-directional Impact Protection System (MIPS), an Emergency Release System (ERS), and an Eject inflation system fitment inside the crown of the shell.
