The Alpinestars Youth SM3 Helmet is designed for young riders who need dependable impact protection, a comfortable fit, and efficient ventilation. This Falcon colorway combines blue, white, black, and pink fluo graphics with a Large fit for a secure, performance-focused riding experience. The helmet features a thermo-injected outer shell made from an advanced impact-resistant thermoplastic, using strategically varied thicknesses to balance protection and reduced weight. The Alpinestars SM3 helmet is identified by manufacturer part number 8301327-7347-YL and vendor part number 8301327-7347-YL.
The multiple-density inner liner places the appropriate EPS density in key areas to improve impact absorption while helping maintain a lightweight design. Both the inner and outer surfaces are engineered to help reduce the effects of oblique impacts. A low-friction coating on the main EPS liner creates a slip-plane effect intended to reduce rotational acceleration forces associated with certain angled impacts. The visor release system is calibrated to release at a predetermined force, helping reduce forces transferred to the rider’s neck during an impact.
Ten intake vents and seven exhaust ports promote airflow and heat exchange throughout the helmet, while the visor is designed to direct air toward the ventilation openings. The comfort liner uses recycled materials to help reduce environmental impact, and integrated hydration tube channels in the cheek pads provide added convenience during extended rides. Crown and cheek pads are available separately in different thicknesses, allowing the fit to be tailored to the rider’s head.
For secure retention and practical safety, the Youth SM3 includes a soft textile chin strap, stainless steel D-rings, and removable cheek pads with an Emergency Release System. The emergency-release design allows the cheek pads to be removed while the helmet remains on the rider, supporting safer helmet removal after an incident. Three-dimensional contoured foam helps improve comfort, making the Alpinestars Youth SM3 Helmet a well-rounded choice for off-road riding and youth motorsports.
