The Alpinestars SM7 Core off-road helmet is engineered for off-road racing and demanding riding conditions. This XL helmet features a lightweight, multi-layer composite shell made from fiberglass, carbon, and aramid fiber to balance impact protection, force dissipation, sliding performance, energy absorption, stability, and durability. Its aerodynamic profile has a smooth, streamlined surface without external channels that could create load points during an impact. The shell curvature promotes reduced friction and improved deflection, helping transfer energy away from the rider’s head, neck, and spinal column.
Ventilation is provided by 20 individual intake and exhaust ports, including 13 intake ports and 7 exhaust ports, to promote airflow during intense riding. The removable, hand-washable interior uses antimicrobial-treated fabrics, while the adjustable top pad and interchangeable cheek pads allow the fit to be customized. The Alpinestars A-Head system enables height adjustment of the top pad, and replacement cheek pads are available in multiple thicknesses and can be exchanged across shell sizes. The 3D cheek pads include an emergency extraction system and a channel for routing a hydration tube.
The SM7 includes Alpinestars’ Visor Detaching System, designed to release the visor when impact energy exceeds 15 joules, helping reduce 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. Additional features include communication-system compatibility with speaker recesses, integrated hydration channels, a 25 mm nylon chin strap with stainless-steel double-D rings, and removable strap covers for washing. The Alpinestars SM7 Core helmet is finished in matte orange and blue, sized XL, and identified by manufacturer and vendor part number 8301826-408-XL.
