DESCRIPTION
The Alpinestars SM3 Youth MX Helmet is designed specifically for younger riders who need the same level of safety, comfort, and performance as the pros. Anatomically engineered for kids and youth, this lightweight helmet takes technology straight from Alpinestars’ adult helmet range and reshapes it for smaller heads, giving the next generation of riders the ultimate protection out on the track, trail, or paddock.
At Motozone, we know how important it is to keep the young ones safe while they ride. The SM3 Youth blends advanced impact protection, tailored sizing, and rider comfort to make sure every lap, jump, and trail ride is backed by Alpinestars’ leading helmet technology.
Key Features:
~ Youth-Specific Fit – Anatomically engineered shell profile for young riders.
