Alpinestars has introduced a new internal standard for the SM3 Youth to test the helmet's chin bar under more demanding conditions than the homologation standard.

To meet Alpinestars' new requirements, the shell thickness and helmet structure have been optimized in the chin area to provide improved impact performance.

• Emergency Release System and removable cheek pads allow for easy and safe removal of the cheek pads while keeping the helmet securely in place.

• 3D contoured foam ensures optimal rider comfort.

• Stainless steel D-rings guarantee a precise and secure fit.

• Meets DOT certification and ECE 2206 homologation requirements for worldwide use.
