The Alpinestars SM7 helmet is specifically engineered for off-road racing enthusiasts seeking a combination of lightweight comfort and maximum protection. Its aerodynamic composite shell features a smooth, streamlined design that minimizes external load points and enhances overall impact resistance. The shell's curvature promotes reduced friction upon impact, allowing energy to be efficiently deflected away from the rider's head and neck, thereby reducing injury risk. Integrated PLASMA technology at the lower shell edge further enhances energy dissipation in critical collision zones, particularly around the collarbone area. This advanced technology helps to absorb shocks effectively, providing an extra layer of safety in high-impact situations.
Designed for optimal ventilation, the SM7 boasts 20 individual intake and exhaust ports, including 13 intake vents and 7 exhaust outlets, excluding the eye port. These ports work together to facilitate continuous airflow, keeping the rider cool and comfortable during intense off-road sessions. The helmet's fit can be customized with interchangeable cheek pads available in various thicknesses, ensuring a snug and secure fit for different head shapes and sizes. The cutaway section on the left side accommodates communication systems seamlessly, with earphone recesses on both sides for speakers, making communication during races more accessible.
The interior linings are removable and washable, made from antimicrobial fabrics that maintain hygiene and freshness. The crown and neck pads are elastically connected to better manage oblique impacts, while the top pad can be adjusted in height with the A-head system for personalized comfort. Cheek pads feature 3D foam with an emergency extraction system (ERS) and a hydration tube channel, providing added safety and convenience. The chin strap is equipped with a 25 mm nylon strap, stainless steel DD rings, and removable covers for easy cleaning. Integrated channels on both sides allow for hydration system installation, ensuring hydration is readily accessible during competition.
Additional safety features include a visor detaching system designed to release upon impact exceeding 15 Joules, preventing helmet compromise. The visor itself is engineered to detach automatically in high-energy impacts, offering enhanced protection regardless of impact direction. The helmet’s construction incorporates Alpinestars' proprietary PLASMA technology, strategically embedded in the side pads for shock absorption, significantly reducing injury risk. Overall, the SM7 helmet combines advanced safety features, superior ventilation, and customizable comfort to meet the demanding needs of off-road racers, making it an essential choice for serious riders seeking top-tier protection and performance.
