The Alpinestars SM7 helmet is a lightweight, full-coverage off-road racing helmet designed for riders who require advanced impact protection, ventilation, comfort, and stability. This solid gloss black model is available in size XL and features a multi-layer composite shell made from fiberglass, carbon, and aramid fiber. The shell construction is engineered to balance impact protection, force dissipation, sliding performance, energy absorption, and durability for demanding off-road use.
Its aerodynamic profile creates a smooth, streamlined exterior without unnecessary channels or protrusions that could become load points during an impact. The curved shell promotes reduced friction and efficient deflection, helping transfer energy away from the rider’s head and reduce forces referred to the neck and spinal column. The Alpinestars SM7 also incorporates PLASMA technology along the lower side shell area to improve energy absorption in the collarbone region.
Ventilation is provided through 20 individual intake and exhaust ports, including 13 intake ports and 7 exhaust ports, to help manage airflow during intense riding. The removable, hand-washable liner features antimicrobial-treated fabrics, while the adjustable A-Head system allows the top pad height to be customized. Interchangeable 3D cheek pads are available across all shell sizes and include an emergency extraction system, hydration tube channel, and compatibility with Alpinestars replacement pads. Integrated ear recesses and an EPS cutaway accommodate compatible communication systems.
Additional equipment includes a 25 mm nylon chin strap with stainless steel double-D rings, removable strap covers, hydration channels, and a Visor Detaching System. The visor is designed to detach from the shell when subjected to impact energy greater than 15 joules, helping reduce potential weaknesses associated with fixed anchoring systems. Manufactured by Alpinestars, this helmet is intended for off-road racing and performance riding applications. Manufacturer and vendor part number: 8301426-1180-XL.
