The Alpinestars SM7 Solid Matte Black Helmet is engineered for off-road racing and demanding riding conditions. This 2XL helmet features a lightweight composite shell constructed from a carefully balanced blend of fiberglass, carbon, and aramid fiber to provide impact protection, force dissipation, energy absorption, stability, sliding performance, and durability. Its streamlined aerodynamic profile minimizes external load points and promotes smooth deflection during an impact, helping reduce the transfer of direct force toward the rider’s neck and spinal column. The manufacturer is Alpinestars, and the manufacturer and vendor part number is 8301426-110-2X.
The SM7 helmet is designed for comfortable long-term use with an ultra-ventilated shell featuring 20 individual intake and exhaust ports, including 13 intake ports and 7 exhaust ports. Removable, washable linings use antimicrobial-treated fabrics, while the adjustable A-Head system allows the top pad height to be customized for a more secure fit. Interchangeable 3D foam cheek pads are available across shell sizes and include an emergency extraction system, plus an integrated channel for a hydration tube. The crown and neck pads are elastically connected to assist with oblique impact management, and integrated side channels accommodate hydration system routing.
Protection-focused features include Alpinestars PLASMA technology integrated into the side pads for shock absorption near the collarbone area. The Visor Detaching System is designed to release the visor from the shell when exposed to impact energy greater than 15 joules, helping reduce potential weaknesses associated with fixed visor anchoring systems. A 25 mm nylon chin strap with stainless steel double-D rings provides secure retention, and removable strap covers simplify washing. The helmet is communication-system compatible, with an EPS cutaway and ear recesses for intercom speakers. The Alpinestars SM7 2XL is a suitable fitment for off-road racers and riders seeking a ventilated, aerodynamic helmet with customizable comfort and advanced impact-management features.
