The S-M7 Core Helmet is an advanced MX helmet developed for riders who demand lightweight comfort, cooling efficiency, and confidence in aggressive off-road racing. Its aerodynamic composite shell pairs high airflow with proven impact management, while the patented A-Head fitment system fine-tunes helmet position for a secure performance fit. Integrated PLASMA side protection and the visor release system help reduce injury risk in critical crash scenarios.
Aerodynamic profile: The smooth, streamlined shell helps reduce drag and keeps the helmet stable at speed for confident motocross performance.
Energy deflection: The curved shell geometry is engineered to help redirect impact forces away from the head for added rider confidence in a crash.
PLASMA side pads: Alpinestars patented PLASMA integration adds targeted shock absorption in a critical zone to help lower injury risk.
A-Head adjustability: The patented A-Head Fitment System lets riders fine-tune helmet angle and height for a more precise, performance-focused fit.
Visor release system: The patented visor mechanism is designed to detach in a crash, helping reduce the risk of helmet damage and rotational injury.
Impact-release visor: The visor is engineered to separate from the shell above 15 Joules of impact energy for consistent protection from multiple impact directions.
Shell sizing system: Three shell sizes and six consumer sizes from XS to XXL support a more anatomical fit, improving comfort, reducing weight, and maximizing impact effectiveness.
Hydration system ready: Integrated side channels make it easy to route hydration, helping riders stay supplied during demanding off-road sessions.
Multi-layer shell combines fiberglass, carbon, and Aramid fiber to deliver impact protection, force dissipation, energy absorption, and controlled sliding performance.
Patented A-Head Fitment System allows adjustment of the helmet’s angle and height on the head, helping maintain correct protective positioning.
Eject Removal System Ready: the helmet is designed to accommodate installation of an eject removal system and includes a removable insert on top of the EPS.
The fit can be further customized via Alpinestars genuine replacement cheek pads, available in all thicknesses and exchangeable between all shell sizes, to fine-tune secure helmet positioning.
This S-M7 version is homologated to ECE 22.06.
