The Alpinestars SM3 Helmet in Falcon Blue/White/Black/Pink Fluo is engineered for motocross, enduro, and off-road riding. This Medium helmet combines impact protection, ventilation, comfort, and lightweight performance in a thermo-injected shell designed with varying thicknesses. The impact-resistant thermoplastic outer shell works with a composite fiber layer and multi-density EPS liner to help manage impact energy while maintaining a comfortable fit for demanding rides. This helmet is identified by manufacturer and vendor part number 8300927-7347-M.
The SM3 helmet features a six-piece EPS liner using five densities to place the appropriate level of impact absorption where it is needed. A polished EPS surface with a low-friction coating helps reduce friction between the liner and comfort padding, supporting rotational impact management during certain oblique impacts. The inner and outer surfaces are engineered to help minimize the effects of angled impacts. Ten intake ports and seven exhaust ports promote airflow and heat transfer, while the visor design helps direct air into the ventilation system. The visor release system is designed to release at a predetermined force to help reduce forces transferred to the rider’s neck during an impact.
Fit and rider convenience are supported by adjustable crown and cheek pads, 3D-contoured comfort foam, and a recycled-material comfort liner. Integrated hydration tube channels in the cheek pads help keep hydration systems organized during off-road use. The 25 mm soft textile chin strap and stainless steel D-rings provide a secure, comfortable fit. For added protection and serviceability, the helmet includes an Emergency Release System with removable cheek pads, allowing the pads to be removed while the helmet remains in place. The optimized chin area supports impact performance, making the Alpinestars SM3 a versatile choice for riders seeking dependable protection and comfort across motocross, enduro, and off-road applications.
