MotoGP, Ducati 'protects' the air scope mouth of Michele Pirro's GP23

On Michele Pirro's bike, inside the dynamic air intake, these appeared to be what appear to be 'guards' against the ingestion of foreign parts into the intake, It actually happened in the past to Jack Miller to swallow the tear off of Quartararo's helmet in 2020. A rare event, but not impossible.

Perhaps that's why Gigii Dall'Igna thought of this protection. It could also serve to 'clean' the airflow, but we are in the realm of inferences.
