Purpose-built MX and enduro helmet offering advanced impact mitigation, patented low-friction liner technology and exceptional ventilation.
The SM3 Helmet is engineered for MX, enduro and off-road use, featuring innovations and technologies optimized for ease of use, comfort and impact performance.
Shell construction uses a thermo-injected shell with a special polymer blend and variable wall thickness to balance impact protection with lightweight performance.
A patented low-friction coating is applied to the inner EPS liner to reduce rotational acceleration forces from oblique impacts, acting as a slip plane that mimics the brain's cerebrospinal fluid.
The visor release system is patented to ensure visor detachment at a predetermined force, helping reduce neck loads during an impact.
Maximized ventilation and efficient heat transfer are achieved through 10 inlets and 7 exhaust ports for sustained airflow.
Shell composition: 48% acrylonitrile-butadiene-styrene, 20% polyurethane, 16% expanded polystyrene (EPS), 6% polypropylene, 4% polyvinyl chloride, 2% ethylene-vinyl acetate, 2% steel, 1% expanded polypropylene, 1% polyamide.
