The ALPINESTARS Supertech S‑M10 Carbon Motocross Helmet features a streamlined, aerodynamic shell that eliminates external channels or protrusions that could become load points during impact. Its surface curvature reduces friction, allowing energy to deflect and transfer away from the skull, neck, and spinal column. Each size incorporates a dedicated shell dimension to provide an anatomical fit, improving comfort, reducing overall weight, and enhancing impact effectiveness. The chin bar is sculpted with a relief section and raised to clear the collarbone, while a soft EPS liner extends beyond the shell and is covered by a flexible rubber compound to lower the risk of collarbone injury. The A‑Head Fitment System permits fine adjustment of helmet angle and height, and the helmet’s ventilation system includes 28 individual intake and exhaust ports (18 intakes, 10 exhausts) for optimal airflow.
Safety performance is reinforced by several integrated systems. The helmet incorporates an eject helmet removal system and an Emergency Release System (ERS) that includes an emergency visor release and visor extension. It is engineered to meet rotational acceleration and oblique impact criteria. Removable side pads, made from a semi‑soft polymer, provide additional contact area to spread impact energy. These features collectively enhance rider protection while maintaining a lightweight, comfortable fit.
