The S-M7 helmet is designed for off-road racing and is optimized to offer the perfect balance of superior ventilation and comfort in a lightweight helmet, while its extremely aerodynamic composite shell provides exceptional impact protection. In addition to Alpinestars' patented A-Head Fit and Visor Detaching systems, the S-M7 features innovative PLASMA technology on the lower edge of the shell for optimal energy dissipation in the event of contact with the clavicle area.

Aerodynamic Design: The aerodynamic profile of the S-M7 provides a smooth, aerodynamic shell free of external channels and features that could act as load points in the event of an impact or compromise the overall integrity of the helmet's construction.

Energy-Deflecting Design: The helmet's curved shell is designed to reduce drag and deflect impact forces away from the head, helping protect the skull, neck, and spine in the event of a crash.

PLASMA Inside: Alpinestars' patented PLASMA technology is strategically integrated into the S-M7's side pads for high-performance shock absorption in a critical area, significantly reducing the risk of injury.

A-Head Technology: Alpinestars' patented A-Head fit system allows for easy adjustment of the helmet's angle and height on the head for an optimized fit.

Patented Visor Release: The S-M7's patented visor release system is designed to release during a crash, reducing the risk of helmet damage or rotational injury. The S-M7's visor is designed to automatically release from the shell when subjected to impact energy exceeding 15 Joules for optimal impact protection, regardless of direction.

Shell Sizing for Optimal Fit: The S-M7's shell sizing solution ensures each helmet size offers the most suitable anatomical solution for the wide range of fit needs worldwide. It offers three different shell sizes and six consumer sizes from XS to XXL to ensure riders get the correct fit that not only improves comfort and reduces overall weight, but also improves the helmet's effectiveness in the event of an impact.

Hydration System Ready: The helmet incorporates integrated channels on both sides to accommodate a hydration system.

The multi-layered shell is constructed from a blend of fiberglass, carbon, and aramid fiber for the best balance of impact protection and force dissipation, glide performance, energy absorption, stability, and durability.

The patented A-Head fit system allows for easy adjustment of the angle and height at which the helmet sits on the head.

Ultra-ventilated helmet with 20 individual vents and exhaust ports, excluding the eye port, with 13 intakes and 7 exhausts, for optimal 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 Liner: Featuring 3D foam for optimal comfort, the liner features an antimicrobial treatment for long-lasting freshness.

The fit of the S-M7 can be further customized with Alpinestars' genuine replacement cheek pads, available in all thicknesses and interchangeable between all shell sizes.

Lightweight: ECE 1280g and DOT 1340g for a size medium.

The S-M7 is available in the ECE2206 homologation standard.
