The rear air vent on the LS2 FF811 Vector also known as the rear exhaust port—is a crucial component of the helmet’s dynamic flow‑through ventilation system. It works in concert with the chin and top intake vents and internal channels to expel warm, humid air, helping maintain a steady, refreshing airflow and ensuring rider comfort across long or hot rides.
Features
Functions as part of the helmet’s Dynamic Flow‑Through Ventilation system, facilitating the exit of hot air and maintaining a consistent, cooling internal airflow.
Precisely aerodynamically designed to integrate seamlessly with the helmet’s shell and help reduce turbulence.
Replacement rear air vent (LS2 FF811/OF603) is available as an OEM accessory, featuring a snap-fit design made from durable, high-impact plastic. It ensures a secure, rattle-free fit and maintains airflow performance.
