The Alpinestars SM7 Core helmet is engineered for off-road racing and demanding powersports use, combining a lightweight composite shell with advanced impact protection, ventilation, stability, and comfort. The white, blue, orange, and pink helmet is offered in Medium and features a multi-layer shell constructed from fiberglass, carbon, and aramid fiber. This optimized blend helps manage impact forces, support energy absorption, and promote sliding performance while maintaining a streamlined, aerodynamic profile. The manufacturer and vendor part number is 8301826-2088-M.
The SM7 uses an aerodynamic shell design without external channels or protruding features that could create load points during an impact. Its curved profile helps reduce friction and promote controlled deflection, supporting protection against direct and transferred forces. Alpinestars PLASMA technology is integrated into the lower side pads to provide high-performance shock absorption near the collar bone area. The Visor Detaching System is designed to release the visor when subjected to significant impact energy, helping reduce the risk associated with rigid visor anchoring systems.
Ventilation is provided through 20 individual intake and exhaust ports for effective airflow during demanding rides. The removable, washable interior uses antimicrobial-treated fabrics, while the adjustable top pad and interchangeable cheek pads allow riders to customize the fit. The cheek pads include an emergency extraction system, a hydration tube channel, and compatibility across all shell sizes. Integrated side channels accommodate hydration systems, and the EPS includes a cutaway for intercom installation with earphone recesses on both sides. A 25 mm nylon chin strap with stainless steel double-D rings provides secure retention, and removable strap covers simplify cleaning. The Alpinestars SM7 is a purpose-built off-road helmet for riders seeking advanced protection, customizable fit, communication-system compatibility, and dependable comfort on race courses and trails.
