Engineered for motocross, enduro and off‑road use with a thermo‑injected multi‑density shell, low‑friction EPS liner, patented visor release and high ventilation.
This helmet is engineered for motocross, enduro and off‑road riding, balancing comfort, ease of use and impact performance. 🚵
The thermo‑injected shell incorporates a special polymer blend with variable wall thickness to optimize protection while keeping weight low.
An innovative low‑friction layer on the inner EPS liner reduces rotational acceleration from oblique impacts by mimicking the brain's cerebrospinal fluid slip plane.
A patented visor release system reduces neck forces by allowing the visor to release at a predetermined force, and ventilation is maximized with multiple inlets and exhaust ports for efficient heat transfer. 🌬️
Composite construction combines several engineered materials to manage impact energy and durability across varied off‑road conditions.
