HJC I71 SIMO full face helmet: The i71 sets new standards 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 optimize weight and comfort for the rider. The repositioned top vent and enlarged chin vent allow for improved airflow and ventilation. Also new on the i71 are the visor and sun visor. The HJ-38 Pinlock visor is equipped with a new push-slide locking system that ensures more security, but is still easy to use even with gloves. The new sun visor offers the driver the option of adjusting the sun visor forward in 3 positions to ensure ideal sun visor protection. The i71 is also compatible with the second generation Smart HJC Bluetooth systems.
