The Alpinestars SM7 Cast helmet is engineered for off-road racing and combines advanced impact protection, ventilation, comfort, and lightweight performance. Its composite shell uses a carefully developed blend of fiberglass, carbon, and aramid fiber to help manage impact forces, improve energy absorption, and support durability. The aerodynamic shell profile is smooth and streamlined, with a curvature designed to reduce friction during an impact and promote efficient deflection away from the rider’s head, neck, and spinal column. This SM7 helmet is finished in Red/Yellow Fluo/Blue and is supplied in size XS for riders requiring a compact fit.
The SM7 features 20 individual intake and exhaust ports, including 13 intake ports and 7 exhaust ports, to promote consistent airflow during demanding rides. The A-Head system allows the top pad to be adjusted for a more personalized fit, while interchangeable Alpinestars cheek pads are available across all shell sizes for additional fit customization. Removable, washable liners use antimicrobial-treated fabrics, and the crown and neck pads are elastically connected to assist with oblique impact management. The cheek pads include 3D foam, an emergency extraction system, and a channel for routing a hydration tube. Integrated side channels also support hydration system installation.
Protection features include the Alpinestars Visor Detaching System, which is designed to release the visor from the shell when subjected to impact energy greater than 15 joules, helping reduce weaknesses associated with fixed anchoring systems. PLASMA technology is integrated into the lower side pads to support energy dissipation in the collar bone area and enhance shock absorption. The helmet includes a 25 mm nylon chin strap with stainless steel double-D rings and removable covers for cleaning. A cutaway section in the EPS and recessed areas for speakers make the SM7 compatible with select communication systems. The manufacturer part number and vendor part number are both 8302626-3226-XS.
