The Alpinestars Supertech R7 S-R7 Helmet combines a lightweight carbon composite shell with advanced protection and performance technologies for track and street riding. This A-Core helmet is finished in Gloss Red/White and sized 2XL. Its multi-composite outer shell uses carbon, aramid fiber, and fiberglass layers bonded with pre-preg epoxy resin to provide high strength, effective energy dissipation, radial strength, and penetration resistance. Collarbone recesses feature PLASMA inserts engineered to help absorb shock and reduce injury risk during a slide. The manufacturer and vendor part number is 8203426-3182-2XL.
The inner shell uses a multi-density EPS liner with seven pieces in six densities, strategically positioned to manage impact energy according to each helmet size. Alpinestars’ low-friction coating creates a slip plane designed to help reduce rotational acceleration during oblique impacts, supporting protection against concussion and other brain injuries. The optimized eye port provides a broad field of view, while the aerodynamic shell, integrated spoiler, and lateral winglets help reduce turbulence, drag, and neck strain during high-speed riding. The helmet is designed to fit riders requiring a 2XL full-face application for compatible track and road use.
Airflow is managed through 10 ventilation ports, including chin and upper intake vents with a slidable top vent mechanism, plus lateral chin-bar and rear exhaust ports. Chin vents direct air toward the inside of the shield to help reduce fogging and misting, while extractor vents remove humid air from the interior. An ECE 22.06 homologated optical Class 1 shield with double-sided anti-scratch treatment provides clear visibility and durable everyday performance. The Alpinestars Supertech R7 S-R7 Helmet is supplied in the Gloss Red/White A-Core configuration and is identified by part number 8203426-3182-2XL.
