The Alpinestars SM7 Core Helmet is a lightweight, competition-focused off-road helmet designed for riders who demand advanced impact protection, ventilation, comfort, and dependable fitment. Finished in Gloss Red and offered in Medium, this helmet features a multi-layer composite shell constructed from fiberglass, carbon, and aramid fiber. The blend is engineered to balance impact protection, force dissipation, sliding performance, energy absorption, stability, and durability for off-roading and racing applications. The aerodynamic shell profile minimizes external channels and potential load points while promoting smooth deflection during an impact.
Ventilation is provided by 20 dedicated intake and exhaust ports, including 13 intake ports and 7 exhaust ports, to help manage airflow during demanding rides. The A-Head Fitment system allows the top pad to be adjusted for a more personalized fit, while interchangeable cheek pads are available across all shell sizes to further refine comfort. Removable, washable interior liners feature antimicrobial fabric treatment, and the cheek pads include 3D foam, an emergency extraction system (ERS), and a channel for hydration tube routing. The 25 mm nylon chin strap uses stainless steel double-D rings and includes removable covers for washing.
The SM7 incorporates Alpinestars PLASMA technology into the lower side pads to help absorb energy near the collarbone area. Its Visor Detaching System is designed to release the visor when subjected to impact energy greater than 15 joules, helping reduce potential load transfer regardless of impact direction. Integrated communication-system recesses accommodate speakers on both sides, and a left-side EPS cutaway supports intercom installation. The Alpinestars SM7 Core Helmet, manufacturer and vendor part number 8301826-3127-M, is designed for off-road racing and powersports riders seeking a secure, ventilated, and customizable helmet fit.
