The SM3 Force helmet is engineered for MX, Enduro and off-road use, combining ease of use, comfort and impact performance. 🏁
The thermo-injected shell uses a special polymer blend with variable thickness to balance impact protection and low weight.
An innovative low-friction coating is applied to the inner EPS liner to reduce rotational acceleration from oblique impacts, acting as a slip plane similar to cerebrospinal fluid. 🧠
The patented visor release system ensures the visor detaches at a pre-determined force to reduce neck loads during impact.
Ten inlets and seven exhaust ports maximize ventilation and heat exchange for sustained riding comfort.
Composite construction includes ABS, polyurethane, polystyrene (EPS) and other engineered materials for structural integrity and energy management. ⚙️
