🛡️ The SM7 helmet is engineered for off-road racing, combining impact protection and rider comfort for high-speed and technical terrain.
Its outer shell composite construction is lightweight and durable, and the aerodynamic profile is designed to reduce friction on impact, allowing deflection and efficient transfer of energy away from the head toward the neck and spinal column.
Thanks to 20 individual intake and exhaust ports (not including the eye port), with 13 intakes and 8 exhausts, the helmet delivers ultra-ventilation to keep the rider cool during extended efforts.
The patented visor detaching system is engineered to automatically detach the visor from the shell when subjected to an impact energy greater than 15 joules, optimizing impact protection regardless of direction.
Linings are removable and washable for easy maintenance, while cheek pads are fitted with 3D foam and an emergency extraction system (ERS); they include a channel for a hydration tube and are interchangeable among all sizes.
Alpinestars patented Plasma technology is strategically integrated into the side pads for high-performance shock absorption in critical areas, helping to reduce the risk of injury.
The crown pad and neck pad are elastically connected to improve oblique impact management, and the top pad is removable and height-adjustable via the A-head system.
The chin strap features a 25 mm width nylon strap with stainless steel double-D rings and removable covers for washing.
The shell sizing solution provides dedicated shell sizes for each fit size, and three different helmet shell sizes plus multiple consumer sizes ensure an anatomical fit; fit can be further customized with genuine replacement cheekpads. Both sides have integrated channels to accommodate a hydration system, and a cutaway section on the left-side of the EPS allows seamless integration of communication systems with earphone recesses on both sides.
