Motorsports helmets are designed with ventilation in mind for people who aren't breathing vigorously and have air being force fed at high velocity through the ports to dissipate moisture (before it freezes) and CO2.
I own (and use for their intended purpose) two full face moto helmets and wouldn't think of using them on a bicycle.
