The Alpinestars SM7 Blaster helmet is engineered for off-road racing and high-performance riding, combining advanced impact protection, ventilation, comfort, and aerodynamic efficiency. This Large-size helmet features a lightweight composite shell constructed from a blend of fiberglass, carbon, and aramid fibers to balance force dissipation, energy absorption, sliding performance, stability, and durability. Its streamlined shell profile is free of external channels that could create load points during an impact, while the shell curvature helps promote deflection and reduce friction to manage energy more efficiently.
The SM7 uses an ultra-ventilated design with 20 individual intake and exhaust ports, including 13 intake vents and 7 exhaust vents, to support consistent airflow during demanding rides. Removable, hand-washable liners feature antimicrobial fabric treatments, and the adjustable crown pad works with the A-Head Fitment System for a customized fit. Interchangeable 3D foam cheek pads are available across all shell sizes and include an emergency extraction system, a hydration tube channel, and compatibility with Alpinestars replacement cheek pads. The helmet also includes integrated channels for hydration systems and a cutaway EPS section with earphone recesses to accommodate compatible communication systems.
Protection features include the Alpinestars Visor Detaching System, which is designed to release the visor when impact energy exceeds 15 joules, helping reduce stress on the helmet and rider regardless of impact direction. PLASMA technology is integrated into the lower side pads to provide targeted shock absorption near the collarbone area. A 25 mm nylon chin strap with stainless steel double-D rings provides secure retention, while removable strap covers simplify cleaning. This Alpinestars SM7 helmet is finished in the Blaster Black/Gray/White/Yellow Fluo colorway and is supplied in Large size. Manufacturer part number and vendor part number: 8301627-1697-L.
