Which rider is it for?

Indicative MotoComparo positioning, based on the uses described by the manufacturer and the press.

The Thunder 4 SV has the lines of a sports helmet and the equipment of an everyday helmet. Its HIRP polymer blend shell is complemented by a clear visor and a sun visor. MT-AFCS ventilation and the micrometric fastening make it easy to live with in town and over medium distances.

Shell material

Thermoplastique. Un plastique moulé (polycarbonate, ABS) : la coque la plus abordable, mais un peu plus lourde.

All approved helmets pass the same tests: the material mostly tells you the weight and the price, not the safety level.
