Chin bar is flimsy it feels that it’s not closing all the way and rattling. My riding partners was complaining in cracking noises out of my helmet though intercom system. For the test reason I have asked one of my friends to ride with my helmet and I can confirm that all this cracking noises are from MY RPHA91 helmet chin bar,Really annoying. Hope to receive recall massage from HJC Europe for knowing issue with chin bar.
