Expertly designed for off-road racing, the S-M7 Core Helmet is Alpinestars' high-performance solution for riders seeking superior ventilation and lightweight protection. Featuring an ECE 22.06 certified composite shell with integrated PLASMA technology and the patented A-Head Fitment System, it delivers exceptional impact dissipation and a customized fit. Includes: a hydration tube routing system and a crash-responsive patented visor release system.

Key features

Aerodynamic Design: Smooth, streamlined shell profile without external channels to eliminate potential load points during impact and maintain structural integrity.
Energy-Deflecting Design: Engineered curved shell reduces friction and deflects impact forces away from the head to protect the skull, neck, and spine.
PLASMA Inside: Patented Alpinestars PLASMA technology integrated into side pads provides high-performance shock absorption in critical zones to reduce injury risk.
A-Head Technology: Patented A-Head Fitment System allows for precise adjustment of the helmet's height and angle on the head for an optimized, stable fit.
Patented Visor Release: Visor is designed to detach during a crash to prevent rotational injury or helmet damage; automatically releases when subjected to impact energy greater than 15 Joules.
Shell Sizing for Optimal Fit: Three shell sizes and six consumer sizes (XS-XXL) ensure an anatomical fit, reducing weight and maximizing impact effectiveness for every rider.
Hydration System Ready: Integrated internal channels on both sides of the helmet allow for seamless compatibility with hydration systems.

Protection

Multi-layer shell is constructed from a blend of fiberglass, carbon, and Aramid fiber for the optimum blend of impact protection and force dissipation, sliding performance, energy absorption, stability and durability.
Patented A-Head Fitment System allows easy adjustment of the angle and height that the helmet sits on the head.
Ultra-ventilated helmet with 20 individual intake and exhaust ports, not including the eye port, with 13 intakes and 7 exhausts, for optimum ventilation.
Eject Removal System Ready: the helmet is designed to accommodate the installation of an eject removal system, which includes a removable insert on top of the EPS.
Removable Lining: With a 3D foam for optimum comfort, the lining features an anti-microbial treatment for long-lasting freshness.
The S-M7's fit can be further customized via the Alpinestars genuine replacement cheek pads, which are available in all thicknesses, and are exchangeable between all shell sizes.
Lightweight: ECE 1280g and DOT 1340g for a size medium.
The S-M7 is available in 2 versions: ECE 22.06 and DOT homologation standards.

Construction

Shell construction utilizes advanced molding technology with a pre-preg composite lay-up.
Engineered shell design delivers effective linear and oblique impact protection.
Internal shape and specific EPS liner coating coupled with comfort liner surfaces provide rotational impact protection.
Patented specific coating technology reduces rotational acceleration transmitted to the head, exceeding ECE 22.06 standards by 76%.
Profiled chin bar for integrated impact protection.
