The Alpinestars SM7 Helmet Core in Matte Orange/Blue, size 2XL, is specifically engineered for off-road racing enthusiasts seeking maximum protection and comfort. Its lightweight composite shell features an aerodynamic profile designed to minimize drag and optimize stability at high speeds, with a smooth, streamlined surface free of external channels that could compromise structural integrity. The shell's curvature reduces friction upon impact, promoting energy deflection and efficient transfer to safeguard the rider’s head, neck, and spinal column. Incorporating ALPINESTARS PLASMA technology at the lower side of the shell enhances energy dissipation in contact with the collarbone area, significantly reducing injury risk during collisions. The helmet's design includes 20 individual intake and exhaust ports—13 for air intake and 7 for exhaust—to ensure exceptional ventilation, keeping riders cool during intense off-road conditions. The adjustable fit is further customizable with exchangeable cheek pads available in various thicknesses, allowing for a tailored fit across all shell sizes. The helmet is communication system compatible, featuring a cutaway section on the left side of the EPS foam to seamlessly accommodate intercom systems, along with recesses for speakers on both sides. Constructed with removable, washable linings treated with antimicrobial fabrics, the SM7 maintains hygiene and comfort. The crown and neck pads are elastically connected to better manage oblique impacts, while the removable and height-adjustable top pad offers personalized comfort via the A-head system. Cheek pads utilize 3D foam with an emergency extraction system (ERS) and include channels for hydration tubes, with interchangeability across sizes. The chin strap employs a 25 mm nylon strap with stainless steel DD rings and removable covers for easy cleaning. Integrated channels on both sides facilitate hydration system installation. For impact protection, the visor features a detaching system designed to release when subjected to impact energies exceeding 15 Joules, preventing injury from secondary impacts. The helmet's construction emphasizes safety and durability, making the Alpinestars SM7 a top choice for off-road racers demanding high-performance gear that combines ventilation, impact absorption, and advanced safety features.
