The HJC i90 Chin Curtain is a replacement accessory designed for i90 helmet models. It fits into the chin area to help limit wind and cold air entering from the bottom of the helmet during cooler rides.
By reducing airflow around the chin, this chin curtain can help cut down on buffeting at speed and improve overall comfort in cool to cold conditions. It’s a straightforward way to refresh a worn or missing curtain, or to add extra wind control when temperatures drop.
Ventilation
Built to help block cold air and wind from entering through the helmet’s chin area. By limiting that bottom-up airflow, it can make riding in cool weather feel less drafty and more comfortable without changing the helmet itself.
Aerodynamics
This i90 chin curtain is intended to help reduce buffeting caused by air coming up into the helmet at speed. It’s a practical replacement part for riders who notice extra turbulence around the lower edge of the helmet.
Installation
Designed as a chin curtain accessory for i90 helmet models. It’s meant to replace the existing curtain, making it useful when the original is worn out, damaged, or missing and the rider wants to restore the helmet’s intended wind management.
Ventilation
Installed at the bottom of the helmet, the i90 chin curtain is positioned to limit wind intrusion through the chin opening. That helps keep cold air from flowing up into the chin area, which can improve warmth and comfort in cool to cold conditions. It can also help calm airflow that contributes to buffeting while riding at speed, making the helmet feel steadier in moving air.
Installation
This is a replacement chin curtain intended for HJC i90 helmet models. It’s offered as a dedicated accessory piece for the i90, so riders can replace a worn or missing curtain and maintain the helmet’s fit and airflow control as originally set up for chilly-weather riding.
