Engineered for motocross, enduro and off‑road use, this helmet balances ease of use, comfort and impact performance.

The thermo‑injected shell features a special polymer blend with variable thickness to deliver an optimal combination of impact protection and light weight.

A patented low‑friction coating is applied to the inner EPS liner to reduce rotational acceleration that can result from certain oblique impacts.

This slip‑plane layer mimics the brain's low‑friction cerebrospinal fluid, the body's natural defence against oblique impacts.

A patented visor release system ensures the visor releases at a predetermined force, effectively reducing forces on the neck during an impact.

Maximized ventilation and high heat transfer are achieved through 10 inlets and 7 exhaust ports for effective airflow.
