The SM3 Youth helmet is anatomically engineered and profiled specifically for younger riders, optimized for motocross, enduro and off‑road use.
A thermo‑injected outer shell uses a special polymer blend with varying thicknesses to balance impact protection and low weight; the lightweight shell is produced in three youth shell sizes and the helmet weighs approximately 1060 g.
Fit can be tailored via crown and cheek pads available as spare parts in different thicknesses; Youth Medium and Youth Large share the same EPS size so a YM can be converted to YL as the rider grows, while Youth Small has a dedicated EPS and is adjustable via cheek pads only.
A multi‑density inner liner places appropriate densities where needed for enhanced impact absorption while reducing overall weight, and the inner and outer surfaces are engineered to minimize the effects of oblique impacts.
A patented low‑friction coating is applied to the inner EPS liner to reduce rotational acceleration from oblique impacts by providing a slip plane similar to the brain's cerebrospinal fluid.
The visor includes a patented release system that disengages with a predetermined force to help reduce neck loads in an impact, and an emergency release system allows safe, simple removal of cheek pads while the helmet remains on.
Comfort and safety details include a 25 mm soft textile chin strap, stainless steel D‑rings for secure fastening, integrated hydration tube channels in the cheek pads, and maximized ventilation with 10 inlets and seven exhaust ports; the visor is shaped to direct air into the vents for improved airflow. 🚵♂️🌬️
