The Alpinestars SM7 Helmet is designed specifically for off-road racing enthusiasts seeking superior protection, ventilation, and comfort. Its lightweight composite shell features an aerodynamic profile that ensures a smooth, streamlined shape, reducing air resistance and enhancing stability at high speeds. The shell's curvature promotes energy deflection upon impact, minimizing transfer forces to the rider's head and neck, while PLASMA technology integrated into the side pads offers high-performance shock absorption to further reduce injury risks. The helmet's design incorporates a cutaway section on the left side for seamless communication system installation, with earphone recesses on both sides for enhanced rider connectivity.
Ventilation is a key feature of the SM7, equipped with 13 intake and 7 exhaust ports, ensuring optimal airflow to keep the rider cool and comfortable during intense off-road sessions. The helmet's removable, washable liners are treated with antimicrobial fabrics, maintaining hygiene and freshness over time. The crown and neck pads are elastically connected to manage oblique impacts effectively, and the top pad is adjustable in height via the A-Head system to customize fit. Cheek pads, made from 3D foam, are interchangeable among all shell sizes and include an emergency extraction system for quick removal in emergencies, as well as a channel for hydration tube installation.
Safety features include a visor with a detaching system that releases upon impact energies exceeding 15 Joules, preventing additional injuries. The helmet's chin strap employs a 25mm nylon strap with stainless steel DD rings and removable covers for easy cleaning. Its composite shell is free of external channels or protrusions, maintaining structural integrity and impact resistance. Designed for durability and performance, the SM7 helmet combines advanced materials like PLASMA technology and innovative construction details to offer comprehensive protection and comfort for off-road racers.
