Alpinestars S-M7 CAST Motocross Helmet Red Yellow Fluo Blue

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 offers 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 collarbone area.

Technical Data Sheet:

Main Features

• PLASMA Inside: Alpinestars’ patented PLASMA technology is strategically integrated into the S-M7’s lateral pads for high-performance shock absorption in a critical area, significantly reducing the risk of injury.
• A-Head Technology: Alpinestars patented A-Head Fitment system allows easy adjustment of the angle and height at which the helmet sits on the head for an optimized fit.
• Hydration System Ready: The helmet incorporates integrated channels on both sides to accommodate a hydration system.
• The patented A-Head Fitment system allows for easy adjustment of the angle and height at which the helmet sits on the head.
• Ultra-ventilated helmet with 20 individual air intakes 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.

Protection

• ECE-2206 approval
• Aerodynamic Design: The S-M7's aerodynamic profile 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 curved helmet shell is designed to reduce friction and deflect impact forces away from the head, helping protect the skull, neck and spine in the event of a crash.
• 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 designed to automatically detach from the shell when subjected to impact energy greater than 15 Joules for optimal protection, regardless of direction.
• Shell Sizing for Optimal Fit: The S-M7's shell sizing solution ensures that each helmet size offers the most suitable anatomical solution for the wide range of fit needs around the world, providing 3 different shell sizes and 6 consumer sizes from XS to XXL to ensure that riders have the right fit, which not only improves comfort and reduces overall weight, but more importantly improves the effectiveness of the helmet in the event of an impact.
• 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, gliding performance, energy absorption, stability, and durability.
• Lightweight: ECE 1280g and DOT 1340g for a size medium.
• The S-M7 is available in the ECE2206 approval standard.
• The unique shell layering process used in the construction of the S-M7 results in extremely effective impact protection. The S-M7's linear and oblique impact performance significantly exceeds current helmet regulations.
• Specific rotational impact protection is provided by the combination of the internal shape and specific coating of the EPS liner, coupled with a specially developed surface in the comfort liner. This Alpinestars patented specific liner technology reduces rotational acceleration transmitted to the rider's head: the S-M7 helmet exceeds the new ECE 22.06 peak rotational acceleration standard by 76%.
• Contoured chin bar for proven impact protection.

Construction

• 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 using Alpinestars genuine replacement cheek pads, which are available in all thicknesses and interchangeable between all shell sizes.
• The helmet shell construction utilizes highly advanced molding technology with a pre-preg composite construction that delivers improved mechanical performance at an ultra-light overall weight.
