Alpinestars – S-M7 Dasher Helmet

Engineered for off-road racing, the Alpinestars S-M7 Helmet delivers a powerful combination of lightweight comfort, superior ventilation, and cutting-edge impact protection. Its sleek aerodynamic shell minimizes drag and avoids external features that could create load points in a crash, ensuring structural integrity and performance.

The S-M7 features Alpinestars’ patented PLASMA technology, strategically integrated into the lower shell edges to reduce collarbone impact risks through advanced shock absorption. A curved shell profile further enhances safety by deflecting energy away from the skull, neck, and spine during impacts.

Fit is optimized through the A-Head Fitment System, allowing easy adjustment of helmet height and angle. For additional safety, the Patented Visor Release System is engineered to detach upon impact exceeding 15 Joules, reducing rotational forces and potential damage.

With three shell sizes covering six helmet sizes (XSXXL), the S-M7 ensures an anatomically precise fit for a wide range of riders. Built-in channels on both sides of the shell make it hydration-system ready, rounding out a feature-packed helmet designed for performance and protection in demanding riding conditions.

Key Features:

• Aerodynamic Design: The S-M7s 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 helmets construction.
• Energy-Deflecting Design: The helmets 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 patented PLASMA technology is strategically-integrated into the S-M7s 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.
• Patented Visor Release: The S-M7s patented Visor Release System is designed to detach during a crash, reducing the risk of helmet damage or rotational injury.
• The S-M7s 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.
