The Alpinestars SM3 Helmet in the Falcon colorway is designed for motocross, enduro, and off-road riders who demand dependable impact protection, ventilation, comfort, and lightweight performance. This Medium helmet features a thermo-injected shell made from an impact-resistant thermoplastic polymer blend with strategically varied thicknesses. The design balances protection and weight while providing a durable platform for demanding trail and track use. Manufacturer and vendor part number 8300927-3206-M identifies this specific Alpinestars SM3 configuration in Red Fluo, White, Blue, and Yellow Fluo.
The SM3 uses a composite fiber layer positioned between the outer shell and EPS liner to enhance impact protection. Its multi-density inner liner uses six EPS sections and five densities to place the appropriate energy-absorbing material in key areas while helping reduce overall helmet weight. A low-friction coating on the main EPS liner is engineered to help manage rotational acceleration during certain oblique impacts. The inner and outer surfaces work together to reduce the effects of angled impacts, while the visor release system is designed to release at a predetermined force to help reduce stress transmitted to the rider’s neck during an impact.
Ventilation is optimized through ten intake ports and seven exhaust ports, with the visor directing airflow into the helmet for improved heat exchange during active riding. The recycled-material comfort liner supports a lower-impact manufacturing approach and can be adjusted with the included crown and cheek pads for a personalized fit. Integrated hydration tube channels help keep hydration equipment accessible, while removable cheek pads and the Emergency Release System support safer helmet removal after an incident. A contoured chin area, soft textile chin strap, stainless steel D-rings, and a secure adjustable fit complete the protection and comfort package. The Alpinestars SM3 is suited for riders seeking a performance-focused off-road helmet for motocross, enduro, and recreational trail applications.
