The Alpinestars SM7 Deed off-road helmet combines a lightweight composite shell with advanced impact protection, ventilation, and rider-focused comfort. Designed for off-road racing, this XL helmet uses a multi-layer blend of fiberglass, carbon, and aramid fiber to balance impact protection, force dissipation, sliding performance, energy absorption, stability, and durability. Its aerodynamic profile has a smooth, streamlined shell without external channels that could create impact load points, while the curved surface promotes deflection and reduced friction during an impact.
Engineered for demanding off-road use, the SM7 features 20 ventilation ports, including 13 intake ports and 7 exhaust ports, to help maintain airflow during extended rides. The A-Head Fitment System allows the top pad to be adjusted for a more personalized fit, while interchangeable Alpinestars cheek pads allow further customization across all shell sizes. Removable, washable liners feature antimicrobial-treated fabrics, and the 3D cheek pads include an emergency extraction system and an integrated channel for a hydration tube.
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 during impacts from various directions. Alpinestars PLASMA technology is integrated into the lower side pads to improve shock absorption in the collar-bone area. The crown and neck pads are elastically connected to support oblique impact management. A 25 mm nylon chin strap with stainless steel double-D rings provides secure retention, and removable strap covers simplify cleaning.
The Alpinestars SM7 is communication-system compatible, with a left-side EPS cutaway and earphone recesses for speakers. Integrated channels on both sides accommodate a hydration system. This helmet is finished in Gloss Blue/Yellow Fluo and is identified by manufacturer and vendor part number 8302426-7253-XL. It is intended for riders seeking a ventilated, customizable off-road helmet with advanced protection and fit features.
