The Alpinestars SM7 Blaster helmet is engineered for off-road racing and demanding powersports use, combining advanced impact protection, ventilation, comfort, and aerodynamic performance. This White/Blue/Red 2XL helmet features a multi-layer composite shell constructed from fiberglass, carbon, and aramid fiber. The material blend is designed to support impact protection, force dissipation, energy absorption, stability, sliding performance, and long-term durability while maintaining a lightweight feel for extended riding sessions. The aerodynamic shell profile is smooth and streamlined, with no external channels or features that could create load points during an impact. Its curved shape promotes reduced friction and controlled deflection to help manage energy transferred to the rider’s head, neck, and spinal column.
The SM7 uses 20 individual intake and exhaust ports, including 13 air intakes and 7 exhausts, to provide consistent airflow during racing and trail riding. Its A-Head Fitment System allows the top pad to be adjusted for a personalized fit, while interchangeable Alpinestars cheek pads provide additional customization across all shell sizes. The removable, hand-washable crown, neck, cheek, and chin strap coverings feature antimicrobial-treated fabrics for improved comfort and cleanliness. The cheek pads use 3D foam, include an emergency extraction system, and provide a channel for hydration tube installation. Integrated channels on both sides of the helmet further support hydration system routing.
For enhanced protection, the Alpinestars Visor Detaching System is designed to release the visor from the shell when subjected to impact energy greater than 15 joules, regardless of impact direction. PLASMA technology is integrated into the lower side pads to provide targeted shock absorption near the collarbone area and help manage energy during contact. The helmet is communication-system compatible, with an EPS cutaway on the left side and earphone recesses on both sides for speakers. A 25-millimeter nylon chin strap with stainless steel double-D rings provides secure retention, and its removable covers simplify cleaning. This Alpinestars SM7 helmet fits off-road riders seeking a race-focused protective helmet with advanced ventilation and customizable comfort. Manufacturer and vendor part number: 8301627-2217-2X.
