The Alpinestars SM7 Core helmet is an off-road racing helmet designed for riders who demand advanced impact protection, efficient ventilation, and customizable comfort. This 2XL helmet features a lightweight multi-layer composite shell made from fiberglass, carbon, and aramid fiber. The construction is engineered to balance impact protection, force dissipation, sliding performance, energy absorption, stability, and durability during demanding off-road use. Its aerodynamic profile has a smooth, streamlined shell without external channels that could create load points or compromise structural integrity during an impact.
Ventilation is provided through 20 individual intake and exhaust ports, including 13 intake ports and 7 exhaust ports, to promote consistent airflow during riding. The Alpinestars A-Head system allows the top pad to be removed and adjusted for a more personalized fit, while interchangeable cheek pads are available across all shell sizes for additional customization. The removable, hand-washable interior uses antimicrobial-treated fabrics, and the 3D foam cheek pads include an emergency extraction system, a hydration-tube channel, and integrated communication-system compatibility with speaker recesses on both sides.
Protection features include the Alpinestars Visor Detaching System, which is designed to release the visor when subjected to impact energy greater than 15 joules, helping reduce weaknesses associated with fixed visor anchoring systems. PLASMA technology is integrated into the lower side shell pads to help dissipate energy in the collarbone area. The crown and neck pads are elastically connected to assist with oblique impact management. A 25 mm nylon chin strap with stainless-steel double-D rings provides secure retention, while removable strap covers simplify cleaning. The SM7 is designed for off-road racing and fits riders requiring a 2XL helmet size. Manufacturer and vendor part number: 8301826-408-XXL.
