Great post. I won’t be surprised if Gigi engineered some flex into it, because that’s not explicitly banned in the rule book.I don't know if anyone noticed this during FP1.
They showed Gigi in the garage touching the tail fins of the GP24, and there is some flex in those fins; they move when you touch them so they are not completely rigid parts which I assumed they were for the longest time.
I immediately thought of F1's consistently ongoing drama for the last...oh maybe 15 years regarding flexi-front wings that load and unload due to aerodynamics. So it has me wondering now about what exactly are those tail fins doing when the bike is tipped over. I don't believe in spite of all of the super slow motion footage that Dorna shoots, there has been any true focus on what those wings are doing on lean. If I had to guess --I am not an expert so take this with a grain of salt-- when the bike leans, the fins become smaller wings that load through the corner driving the rear tire into the tarmac. It would explain why the Ducati is so exceptional with the rear grip of the bike, and the need to use the rear tire to get through corners quickly.
Of course doing this doesn't mean every other manufacturer can suddenly copy it, because if that were the case, it wouldn't be a Ducati Cup. It's just part of a larger overall cohesive aerodynamic package that works from front to back.
I’ve also seen the Honda rear wings flex under load, but I highly doubt if it was the intended outcome.
