Helmet Alpinestars SM7 Cast Blue Pink Yellow

Elevate 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 offer high energy absorption in crash scenarios.
• The patented A-Head adjustment system allows precise positioning of the helmet angle and height on the head to optimize protective coverage and stability during impacts.
• Prepared for the Eject removal system: designed to accommodate an emergency removal insert at the top to enable safer helmet removal by first response teams.
• Interchangeability of cheek pads across all shell sizes allows 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 injury.
• Integrated PLASMA technology in the side pads provides specific impact absorption in critical contact areas.
• Designed for the attenuation of linear and oblique impacts; the internal EPS shape and patented coating provide mitigation against rotational impacts, reducing maximum rotational acceleration by 76% above ECE 22.06 requirements.
• The profiled chin bar provides integrated front impact protection.
• The shell construction uses advanced molding technology with a pre-impregnated multilayer composite stack combining fiberglass, carbon fiber, and aramid fiber.
• The external shell profile, designed with controlled layer orientations, manages linear and oblique impact loads.
• The internal shape and proprietary low-friction coated EPS liner, combined with the comfort liner surfaces, provide mitigation of rotational impacts.
• 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.
• Energy-dissipating PLASMA inserts integrated into the lower side pads of the shell for load management in the clavicle area.
• Approximate weight: 1280 g (size M ECE).
