HJC C91 Kaon Helmet

The HJC C91 modular helmet is a straight to the point helmet, the point being lightweight, super comfortable, affordable, safe, and easy to use. The modular design had gloved hands in mind with an easy to operate chin bar, drop-down sun visor, and faceshield for seamless functionality. The C91 also comes Smart HJC ready (Bluetooth sold separately) with speaker pockets for an easy install that won't rub your ears wrong. DOT approved, wrapped in an advanced polycarbonate composite shell, SuperCool Interior with a glasses groove, the C91 is a 1-2 punch that won't rub your wallet wrong, either.

Note: Customers have found this helmet to run small and recommend sizing up if in between sizes.

Features:

  • DOT Approved
  • Advanced polycarbonate composite shell
  • HJ-17 Pinlock-ready face shield (Pinlock insert sold separately) 
  • HJ-V5 drop-down inner sun visor
  • SuperCool interior
  • Glasses groove integrated into cheek pads
  • Speaker pockets for Bluetooth communication
  • Direct compatibility with SmartHJC 10b or 20b Bluetooth systems (sold separately)
