HJC i 71 full-face helmet - SIMO MC-1 The i71 sets a new standard for a sport-touring model with its new slim shell design. Made from advanced polycarbonate, the helmet now has 3 outer shells and 6 available sizes to optimise weight and comfort for the rider. The repositioned upper vent and enlarged chin vent allow for improved airflow and ventilation. Also new to the i71 are the visor and sun visor. The HJ-38 Pinlock visor is equipped with a new push-slide closure system that provides more security, yet is easy to operate even when wearing gloves. The new sun visor (HJ-V12) offers the rider the ability to adjust the sun visor forward in 3 positions (up to 10 mm) to ensure ideal sun visor protection. The i71 is also compatible with the second generation Smart HJC Bluetooth systems.
