Description
The S-M7 is engineered for off-road racing, and optimised to offer a perfect blend of superior ventilation and confirm in a lightweight helmet.
Its supremely aerodynamic composite shell delivered exceptional impact protection.
As well as Alpinestars patented A-Head Fitment and Visor Detaching Systems, the SM-7 is equipped with innovative PLASMA technology at the lower shell edge for optimum energy dissipation in case of contact with the collar bone area.
Features:
- A smooth, streamlined shell free of any external channels and features that might act as a load point in impact or compromise the overall integrity of the helmet’s construction.
- The shell’s curvature promotes reduced friction on impact, allowing deflection and the mod efficient transfer of energy to protect the rider’s head from the direction for and referred to the neck and spinal column.
- Alpinestars’ patented PLASMA technology is strategically-integrated into the SM-7’s side pads for high performance shock absorption in a critical area, significantly reducing the risk of injuries.
- The Visor Detaching System allows the visor to automatically detach from the shell when subjected to an impact energy greater than 15 Joules for optimum impact protection.
- 20 invidious intake and exhaust ports for optimum ventilation.
- Full removable and washable inner lining
- Integrated channels on both sides to accommodate a hydration system
- Cutaway section on left side of EPS liner to accommodate Intercom Systems, with earphone recesses on both sides for speakers.
