Typically the type of rider who rides without a helmet has some sort of other protection from the wind in the form of a windscreen or fairings on the motorcycle to deflect wind away from their face. It’s mostly a comfort thing though because it’s not impossible to ride without a helmet even without wind protection especially if you’re just cruising around town at lower speeds.
Even people who do wear helmets appreciate these features on their motorcycles because having the wind blasting against your helmet can be very loud and tire out your neck muscles.
Same thing (wind in face) applies to people skydiving though. Some skydivers use full helmets, but a lot don’t, and they’re typically falling at 100+ km/h. I think the “lose your breath from strong wind”-response is just an initial response that disappears once your body adjusts after a couple seconds. I went skydiving once (tandem), and can’t remember getting the same feeling as I do if I stick my head out of a moving car.
