HJC i 71 full-face helmet - SIMO MC-6HSF The i71 sets the standard for a sports touring model with its slim shell design. The advanced polycarbonate helmet now has 3 outer shells and 6 available sizes to optimise weight and comfort for the rider. The rearranged upper ventilation opening and the enlarged chin ventilation opening enable improved air supply and ventilation. Also on the i71 are the visor and sun visor. The HJ-38 Pinlock visor is equipped with a push-and-slide closure system that ensures greater safety and is still easy to operate even when wearing gloves. The sun visor (HJ-V12) offers the rider the option of adjusting the sun visor forwards in 3 positions (up to 10 mm) to ensure ideal sun glare protection. The i71 is also compatible with the second generation Smart HJC Bluetooth systems.
