Description

The Alpinestars S-M7 Helmet is engineered for off-road racing, combining lightweight performance, advanced ventilation, and all-day comfort. Its aerodynamic composite shell is designed to deliver exceptional impact protection while maintaining a streamlined profile for demanding riding conditions.

Featuring Alpinestars’ patented A-Head Fitment System and Visor Detaching System, the S-M7 provides a personalized fit and enhanced functionality. The helmet also incorporates innovative PLASMA technology along the lower shell edge, designed to help dissipate energy in the event of contact with the collarbone area, providing an additional layer of protection for off-road riders.

Features

  • Aerodynamic Shell Design: Features a smooth, streamlined shell profile without external channels or protruding elements that could create potential impact load points or compromise structural integrity.
  • Energy-Deflecting Shell: The curved shell design helps reduce friction and redirect impact forces away from the head, supporting protection for the skull, neck, and spine during a crash.
  • Integrated PLASMA Technology: Alpinestars’ PLASMA technology is strategically incorporated into the helmet’s side pads to provide high-performance shock absorption in critical areas, helping reduce the risk of injury.
  • Patented A-Head Fitment System: Allows riders to easily adjust the helmet’s height and angle for a personalized fit, helping optimize comfort and helmet positioning.
  • Multi-Density EPS Impact Protection: The inner shell uses multi-density EPS foam engineered to provide targeted impact absorption where needed. Each helmet size features a specifically designed EPS liner for a more precise fit and optimized protection.
  • Linear and Rotational Impact Protection: The EPS liner’s internal geometry and specialized coating work together with the comfort liner’s specially developed surface to help reduce rotational acceleration transmitted to the rider’s head.
  • Patented Visor Release System: Designed to allow the visor to detach during a crash, helping reduce the risk of helmet damage and rotational forces.
  • Directional Visor Detachment: The visor is engineered to automatically release from the shell when subjected to impact energy exceeding 15 joules, regardless of the direction of impact, supporting enhanced protection during a crash.
  • Optimized Shell Sizing: Available in 3 shell sizes and 6 consumer sizes, ranging from XS to XXL, to provide a more anatomical fit across a wide variety of head shapes and sizes. The sizing strategy helps improve comfort, reduce unnecessary weight, and optimize helmet performance during an impact.
  • Hydration System Ready: Integrated channels on both sides of the helmet accommodate hydration system routing, making it easier to stay hydrated during extended off-road rides.

Protection

  • Advanced Pre-Preg Composite Shell: Utilizes advanced molding technology and pre-preg composite construction to deliver exceptional mechanical strength and impact performance while maintaining an ultra-lightweight design.
  • Enhanced Impact Protection: The S-M7’s unique shell layup process is engineered to provide highly effective impact protection. Its performance in both linear and oblique impact testing significantly exceeds the minimum requirements of current helmet regulations.
  • Advanced Rotational Impact Protection: Combines the EPS liner’s internal geometry and specialized coating with a specially developed comfort liner surface to help reduce rotational acceleration transmitted to the rider’s head.
  • Patented Coating Technology: Alpinestars’ proprietary coating technology enhances rotational impact protection. The S-M7 exceeds the ECE 22.06 peak rotational acceleration standard by 76%, based on manufacturer testing.
  • Profiled Chin Bar: Engineered to provide effective impact protection while maintaining a comfortable and functional design.
  • Dual Safety Certifications: Available in two homologated versions, with ECE 22.06 and DOT-certified options to meet applicable safety requirements.

Construction

  • Advanced Multi-Layer Shell: Constructed from a combination of fiberglass, carbon fiber, and Aramid fiber to provide an optimized balance of impact protection, energy dissipation, sliding performance, stability, and long-term durability.
  • Patented A-Head Fitment System: Allows riders to easily adjust the helmet’s height and angle for a personalized fit and improved comfort.
  • Advanced Ventilation System: Features 20 dedicated intake and exhaust ports, excluding the eye port, including 13 air intakes and 7 exhaust vents for efficient airflow and enhanced rider comfort.
  • Eject Removal System Ready: Designed to accommodate an Eject Helmet Removal System, with a removable insert located on top of the EPS liner to simplify installation.
  • Removable Comfort Liner: Equipped with 3D-shaped foam for enhanced comfort and an antimicrobial treatment to help maintain freshness during extended use.
  • Customizable Cheek Pads: Fine-tune the helmet’s fit with genuine Alpinestars replacement cheek pads, available in multiple thicknesses and interchangeable across all shell sizes.
  • Communication System Ready: Integrated ear recesses provide space for installing compatible helmet communication systems.
  • Lightweight Construction: Weighs approximately 1,280 g (ECE version) and 1,340 g (DOT version) in size Medium, helping reduce rider fatigue during extended rides.
