Helmet ALPINESTARS S-M7 Core

• Engineered for off-road racing, offering an ideal blend of superior ventilation and comfort in a lightweight helmet, while its highly aerodynamic composite shell delivers exceptional impact protection
• Featuring A-Head Fitment and Visor Detaching System, the S-M7 uses PLASMA technology along the lower shell edge for optimal energy dissipation in the event of contact with the collarbone area
• Key Features
• Aerodynamic profile design provides a smooth, streamlined shell without external channels or features that could act as load points during an impact or compromise the helmet’s structural integrity
• The shell curvature reduces friction on impact, allowing deflection and efficient energy transfer to protect the rider’s head from direct force and force transferred to the neck and spinal column
• Ultra-ventilated helmet with 20 individual intake and exhaust ports, excluding the eye port, including 13 intakes and 7 exhausts for optimum ventilation
• Fit can be further customized with Alpinestars replacement cheek pads, available in all thicknesses and interchangeable between all shell sizes
• Communication System Compatible — Cutaway section on the left side of the EPS accommodates intercom systems, with earphone recesses on both sides for speakers
• Construction
• Linings are removable and hand washable using warm water and neutral soap
• Fabrics feature antimicrobial treatments
• Crown Pad — Crown and neck pads are elastically connected for improved oblique-impact management
• Top Pad — Removable and height-adjustable using the A-Head system
• Cheek Pads — 3D foam cheek pads with an emergency extraction system (ERS) and a channel for hydration tube installation
• Cheek pads are interchangeable among all sizes
• Chin Strap — 25 mm wide nylon strap, stainless steel DD rings, and removable covers for washing
• Integrated channels on both sides accommodate a hydration system
• Protection
• Visor Detaching System features a release mechanism designed to avoid the inherent weaknesses of other anchoring systems
• The visor is engineered to automatically detach from the shell when subjected to impact energy greater than 15 Joules for optimum impact protection, regardless of direction
• PLASMA inside; Alpinestars PLASMA technology is strategically integrated into the S-M7 side pads for high-performance shock absorption in a critical area, significantly reducing the risk of injury
