HJC i 71 Full Face Helmet - ENTA MC-7SF The i71 sets new standards for a sport-touring model with its new, sleek shell design. The helmet, made from advanced polycarbonate, now features 3 outer shells and 6 available sizes to optimize weight and comfort for the rider. The newly arranged top ventilation opening and the enlarged chin ventilation opening allow for improved airflow and ventilation. Also new to the i71 are the visor and the sun visor. The HJ-38 Pinlock visor is equipped with a new push-slide locking system that enhances safety while still being easy to operate with gloves. The new sun visor (HJ-V12) gives the rider the option to adjust the sun visor forward 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.
