Helmet Alpinestars SM7 Cast Blue Pink Yellow

Enhance your riding experience with the Alpinestars SM7 Cast helmet.

Specifications:

• Multilayer composite shell (fiberglass, carbon, and aramid) designed to dissipate impact energy, control sliding, and provide high energy absorption in crash scenarios.
• The patented A-Head adjustment system allows precise positioning of the angle and height of the helmet on the head to optimize protective coverage and stability during impacts.
• Prepared for the Eject extraction system: designed to support an emergency extraction insert at the top to facilitate safer helmet removal by first response teams.
• The interchangeability of the cheek pads across all shell sizes enables secure head stabilization for consistent impact performance and retention.
• Homologations: available in ECE 22.06 and DOT certified versions.
• The curved shell profile with energy deflection reduces friction and helps redirect impact forces away from the skull, neck, and spine.
• Patented visor release system designed to detach when subjected to impact energy above 15 Joules, in order to mitigate rotational load and reduce the risk of secondary injuries.
• PLASMA technology integrated into the side pads provides targeted impact absorption in critical contact zones.
• Designed for both linear and oblique impact attenuation; the internal EPS shape and patented coating provide mitigation against rotational impacts, reducing maximum rotational acceleration by 76% above ECE 22.06 requirements.
• The contoured chin bar provides integrated frontal impact protection.
• The shell construction uses advanced molding technology with a pre-impregnated multilayer composite stacking that combines fiberglass, carbon fiber, and aramid fiber.
• The outer shell profile, designed with controlled layer orientation, manages linear and oblique impact loads.
• The internal shape and EPS liner with proprietary low-friction coating, combined with the comfort liner surfaces, provide mitigation of rotational impacts.
• The patented low-friction coating technology reduces rotational acceleration transmitted to the head, exceeding ECE 22.06 requirements by up to 76%.
• Contoured chin bar with integrated reinforcement for targeted frontal impact structure.
• Energy-dissipating PLASMA inserts integrated into the lower side pads of the shell for load management in the collarbone area.
• Approximate weight: 1280 g (size M ECE).
