Alpinestars Motorcycle helmet S-M7 Deed

Designed for off-road competition, optimised to provide a perfect balance between superior ventilation and comfort in a lightweight helmet. With an aerodynamic composite shell ensuring exceptional impact protection.
A-Head adjustment system and visor detachment system. The S-M7 features PLASMA technology on the lower part of the shell edge for optimal energy dissipation during contact with the clavicle area.
Key features
The aerodynamic profile offers a smooth and sleek shell, with no external channels or components that could act as points of load during an impact or compromise the overall integrity of the helmet.
The curvature of the shell reduces friction upon impact, allowing for optimal energy deviation and transfer to protect the head while limiting transmission to the neck and spine.
Ultra-ventilated helmet with 20 individual air intake and exhaust vents, excluding the eye opening, including 13 intakes and 7 exhausts, for optimal ventilation.
Adjustment can be customised thanks to replaceable cheek pads Alpinestars, available in all thicknesses and compatible with all shell sizes.
Compatible communication system - Cut-out on the left side of the EPS to integrate an intercom, with housing for headphones on both sides.
Construction
Removable and washable liners with lukewarm water and mild soap.
Antimicrobial treated fabrics.
Removable and height-adjustable top crown with the A-head system.
The crown and neck foam are elastically connected for better management of oblique impacts.
Cheek pads - 3D foam, emergency removal system (ERS) and channel for hydration tube.
Cheek pads are interchangeable across all sizes.
Chin strap - 25mm nylon strap, stainless steel DD buckles, removable covers for washing.
Integrated channels on both sides for hydration system.
Protection
Visor detachment system with a release mechanism designed to avoid weaknesses of other anchoring systems.
The visor is designed to automatically detach from the shell when impact energy exceeds 15 joules, ensuring optimal protection regardless of direction.
PLASMA inside: PLASMA technology from Alpinestars is strategically integrated into the side foams of the S-M7 for effective shock absorption in a critical area, significantly reducing the risk of injury.
