The Alpinestars SM7 Cast off-road racing helmet combines advanced impact protection, aerodynamic performance, ventilation, and customizable comfort for serious riders. This 2XL helmet features a multi-layer composite shell made from fiberglass, carbon, and aramid fiber to help balance impact protection, force dissipation, sliding performance, energy absorption, stability, and durability. Its streamlined shell profile is designed without external channels that could create load points, while the smooth curvature helps reduce friction during an impact and promotes efficient energy deflection away from the rider’s head, neck, and spinal column. The helmet is finished in Red, Yellow Fluo, and Blue for a distinctive racing look.
The SM7 includes 20 individual ventilation ports, with 13 intake ports and 7 exhaust ports, to promote airflow during demanding off-road use. Its removable, washable liner features antimicrobial-treated fabrics, while the adjustable top pad works with the A-Head Fitment System to help personalize the fit. Interchangeable cheek pads are available across all shell sizes and include 3D foam construction, an emergency extraction system, and a channel for routing a hydration tube. Integrated side channels also accommodate hydration systems, and a communication-system-compatible EPS cutaway provides space for intercom speakers. The 25 mm nylon chin strap uses stainless steel double-D rings and removable covers for convenient cleaning.
For additional protection, the Alpinestars Visor Detaching System is designed to release the visor from the shell when subjected to impact energy greater than 15 joules, helping avoid weaknesses associated with fixed anchoring systems. PLASMA technology is integrated into the lower side pads and shell edge to support energy dissipation in the collarbone area and help reduce injury risk. The crown and neck pads are elastically connected to assist with oblique impact management. This Alpinestars SM7 helmet is designed for off-road racing applications and is supplied in size 2XL. Manufacturer part number and vendor part number: 8302626-3226-2X.
