The Alpinestars SM3 Helmet in Falcon Blue/White/Black/Pink Fluo is engineered for motocross, enduro, and off-road riding. Designed to balance impact protection, comfort, and reduced weight, this 2XL helmet features a thermo-injected outer shell made from impact-resistant thermoplastic with varied thickness construction. The Alpinestars SM3 helmet uses a composite fiber layer between the outer shell and EPS liner to enhance protection during impacts while maintaining a lightweight riding profile. Manufacturer part number and vendor part number: 8300927-7347-2X.
The SM3 helmet incorporates a six-piece, multi-density EPS liner using five different densities to manage impact performance in specific areas while helping reduce overall weight. A polished inner EPS surface with a low-friction coating helps minimize rotational acceleration forces associated with certain oblique impacts. The helmet's inner and outer surfaces are engineered to help reduce the effects of angled impacts, while the crown and cheek pads allow riders to tailor the fit. Ten intake vents and seven exhaust ports support airflow and heat transfer, with the visor directing air into the ventilation system for enhanced cooling.
Safety and convenience features include a visor release system designed to release at a predetermined force, helping reduce forces transferred to the rider's neck during an impact. The Alpinestars SM3 also includes an Emergency Release System with removable cheek pads for safer helmet removal by trained personnel. Recycled materials are used in the comfort liner to help reduce environmental impact, and integrated hydration tube channels in the cheek pads support practical off-road use. A soft textile chin strap and stainless steel D-rings provide a secure, comfortable fit, while the 3D-contoured foam and optimized chin area support rider comfort and impact performance. This Alpinestars 2XL helmet is suited for riders seeking dependable protection and ventilation for MX, enduro, and off-road applications.
