Helmet Alpinestars SM7 Cast Blue Pink Yellow

Elevate your riding experience with the Alpinestars SM7 Cast helmet.

Specifications:

• Multi-layer composite shell (fiberglass, carbon, and aramid) designed to dissipate impact energy, control sliding, and offer high energy absorption in crash scenarios.
• The patented A-Head fit system allows precise positioning of the helmet’s angle and height on the head to optimize protective coverage and stability during impacts.
• Ready for the Eject extraction system: designed to accommodate an emergency extraction insert at the top for safer helmet removal by first responder teams.
• The interchangeability of the cheek pads across all shell sizes allows secure stabilization of the head 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, to mitigate rotational load and reduce the risk of secondary injuries.
• Integrated PLASMA technology in the side pads provides targeted impact absorption in critical contact areas.
• Designed for attenuation of linear and oblique impacts; the internal shape of the EPS and the proprietary lining provide mitigation against rotational impacts, reducing maximum rotational acceleration by 76% above ECE 22.06 requirements.
• The profiled chin bar provides integrated frontal impact protection.
• The shell construction uses advanced molding technology with a pre-impregnated multi-layer composite stack combining fiberglass, carbon fiber, and aramid fiber.
• The exterior shell profile, designed with controlled layer orientations, manages linear and oblique impact loads.
• The internal shape and the EPS liner with proprietary low-friction coating, in conjunction with 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%.
• Profiled chin bar with integrated reinforcement for targeted frontal impact structure.
• PLASMA energy-dissipating inserts integrated into the lower side shell pads for load management in the clavicle area.
• Approximate weight: 2.82 lb (size M ECE).
