The Alpinestars Supertech R7 S-R7 Helmet combines lightweight carbon composite construction with advanced protection and aerodynamic performance for demanding track and road riders. Finished in Gloss Black/White/Red and sized 2XL, this full-face motorcycle helmet uses a multi-composite outer shell made from carbon, aramid fiber, and fiberglass layers bonded with pre-preg epoxy resin. The result is a strong, lightweight shell designed to provide effective energy dissipation, radial strength, and penetration resistance. The integrated aerodynamic spoiler, lateral winglets, and collarbone recesses help reduce drag, turbulence, and neck strain during high-speed riding. Alpinestars PLASMA inserts in the collarbone areas are designed to improve shock absorption during a slide.
