2023 Alpinestars S-M8 Radium 2 Helmet (Black/Red)

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’.
