The Alpinestars S-M7 is a high-performance off-road racing helmet engineered to provide the ultimate balance of superior ventilation, lightweight construction, and elite impact protection. Its aerodynamic composite shell is specifically designed to minimize drag and maximize safety for professional MX and off-road riders.

High-Tech Composite Construction ✅

Advanced Material Blend: Constructed from a sophisticated mix of fiberglass, carbon, and Aramid fibers for optimal impact dissipation and durability.
Pre-Preg Molding Technology: Utilizes advanced molding processes to ensure mechanical strength while maintaining an ultra-light overall weight.
Three Shell Sizes: Provided in 3 shell sizes across 6 consumer sizes (XS-XXL) to ensure an anatomical fit that improves both comfort and safety effectiveness.
Lightweight Performance: Weighs only 1,280g (ECE) and 1,340g (DOT) for a size medium.

Innovative Safety & PLASMA Technology ✅

PLASMA Inside: Patented PLASMA technology is integrated into the lower edge and side pads to dissipate energy specifically in the collarbone contact area.
Superior Rotational Protection: Features a specialized EPS coating that exceeds the ECE 22.06 Peak Rotational Acceleration standard by an incredible 76%.
Visor Release System: Designed to detach automatically when subjected to impacts greater than 15 Joules, reducing rotational injury risks.
Energy-Deflecting Profile: The smooth, curved shell is engineered to reduce friction upon impact, deflecting forces away from the skull and spine.

Precision Fit & Customization ✅

A-Head Fitment System: A patented adjustment system allows the rider to fine-tune the height and angle of the helmet for a personalized performance fit.
Custom Cheek Pads: Fit can be further tailored with replacement cheek pads available in multiple thicknesses, compatible across shell sizes.
