Alpinestars - S-M7 Cast 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. It adds 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. for confidence when terrain changes or the pace picks up. You get 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. for confidence when terrain changes or the pace picks up.

Why We Like It:

Comfort lands where it counts: steady shell feel, pads that settle in cleanly, and airflow you actually notice when speed drops. The visor and shell cut the wind without tug that wears your neck out across longer motos. Highlights like The S-M7’s aerodynam...

Why It’ll Work for You:

This helmet solves the usual hang‑ups: a fit that dials quickly, cooling you can feel at lower speeds, and impact management tuned for both straight‑on and off‑angle hits. If you’re new to the category, think of it as a simple upgrade in safety and comfort - easy to clean, easy to maintain, and shaped to work with goggles or sunglasses without fuss. It’s a practical, high‑coverage option for daily riding and bigger weekends when pace and terrain change.

Variants / Options:

Color: Blue/Pink/Yellow Fluo Glossy | Sizes from XS to 2X

Key Features:

• 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 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 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-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.
