The S-M7 Helmet is engineered for off-road racing, and is optimized to offer the perfect blend of superior ventilation and comfort in a lightweight helmet, while its supremely aerodynamic composite shell delivers exceptional impact protection. In addition to Alpinestars' patented A-Head Fitment and Visor Detaching Systems, the S-M7 is equipped with innovative PLASMA technology at the lower side of the shell edge for optimum energy dissipation in case of contact with the collarbone area.

• Aerodynamic Design: The S-M7’s aerodynamic profile design offers a smooth, streamlined shell free of any external channels and features that might act as a load point in an impact or compromise the overall integrity of the helmet’s construction.
• Energy-Deflecting Design: The helmet’s curved shell is engineered to reduce friction and deflect impact forces away from the head, helping protect the skull, neck, and spine in the event of a crash.
• PLASMA Inside: Alpinestars' 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 injuries.
• A-Head Technology: Alpinestars patented A-Head Fitment System allows easy adjustment of the angle and height that the helmet sits on the head for an optimized performance fit.
• Inner Shell Linear and Rotational Impact Protection: The inner shell is made in multi-density EPS material to permit the required impact absorption properties exactly where they are required. The EPS liner, just like the outer shell, has its own unique dimension for each helmet size. Specific rotational impact protection is provided by the combination of the internal shape and specific coating of the EPS liner, coupled to a specially-developed surface in the comfort liner. This patented technology reduces rotational acceleration transmitted to the rider’s head.
• Patented Visor Release: The S-M7’s patented Visor Release System is designed to detach during a crash, reducing the risk of helmet damage or rotational injury.
• The S-M7’s visor is engineered to automatically detach from the shell when it is subjected to an impact energy greater than 15 Joules for optimum impact protection, regardless of the direction.
• Shell Sizing for Optimal Fit: The S-M7 shell sizing solution ensures each helmet fit size delivers the most anatomical solution for the wide variety of fit needs worldwide, providing 3 different helmet shell sizes and 6 consumer sizes from XS to XXL to ensure riders have the correct fit which not only improves comfort and reduces overall weight, but most importantly, improves the effectiveness of the helmet in an impact.
Hydration System Ready: The helmet incorporates integrated channels on both sides to accommodate a hydration system.
