Expertly designed for elite off-road performance, the S-M7 Fuse Helmet is Alpinestars' advanced solution for motocross racing, combining a lightweight composite shell with superior ventilation. Featuring patented PLASMA technology and the A-Head Fitment System, it delivers exceptional impact protection and a precision anatomical fit. This ECE 22.06 certified helmet includes a hydration-ready design and an emergency-release visor system for maximum rider safety.

Key features

Aerodynamic Profile: Smooth, streamlined composite shell engineered without external channels to eliminate load points during impact and maintain structural integrity.
Energy-Deflecting Shell: Curved surface design reduces friction upon contact, deflecting impact forces away from the head to protect the skull, neck, and spine.
PLASMA Technology: Patented shock-absorbing material integrated into the side pads provides critical energy dissipation, significantly reducing injury risk in the collarbone area.
A-Head Fitment System: Patented technology allows riders to customize the helmet's height and angle on the head for a personalized, high-performance fit.
Patented Visor Release: Engineered to detach automatically when subjected to impacts exceeding 15 Joules, regardless of direction, to prevent rotational injuries and shell damage.
Anatomical Shell Sizing: Available in 3 shell sizes across 6 consumer sizes (XS-XXL) to ensure an optimized fit that reduces weight and maximizes impact effectiveness.
Hydration System Compatibility: Features integrated internal channels on both sides to facilitate the seamless installation of a hydration tube.

Protection

Multi-layer shell is constructed from a blend of fiberglass, carbon, and Aramid fiber for the optimum blend of impact protection and force dissipation, sliding performance, energy absorption, stability and durability.
Patented A-Head Fitment System allows easy adjustment of the angle and height that the helmet sits on the head.
Ultra-ventilated helmet with 20 individual intake and exhaust ports, not including the eye port, with 13 intakes and 7 exhausts, for optimum 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.
Removable Lining: With a 3D foam for optimum comfort, the lining features an anti-microbial treatment for long-lasting freshness.
The S-M7's fit can be further customized via the Alpinestars genuine replacement cheek pads, which are available in all thicknesses, and are exchangeable between all shell sizes.
Lightweight: ECE 1280g and DOT 1340g for a size medium.
The S-M7 is available in 2 versions: ECE 22.06 and DOT homologation standards.

Construction

Pre-preg composite shell construction utilizes advanced molding technology for enhanced mechanical performance and ultra-light weight.
Unique shell lay-up process delivers extremely effective impact protection, exceeding current linear and oblique regulation standard limits.
Internal EPS liner shape and specific coating are coupled with a developed surface in the comfort liner to provide dedicated rotational impact protection.
Patented Specific Coating technology reduces rotational acceleration, exceeding the ECE 22.06 Peak Rotational Acceleration standard by 76%.
Profiled chin bar engineered for proven impact protection.
