The next two seasons could be interesting regarding the balance of power between KTM, Aprilia and Ducati, particularly between the latter 2 manufacturers. The guestimates about 2027 hint that Aprilia's aero package and philosophy will still be legal because they are using diffuser concepts. The weird lower bodywork on the side fairings that supposedly creates downforce at full lean will still be legal. The ducting they use to draw air around the bike and push it up towards the tail will still be legal. Ducati and KTM, on the other hand, will lose front wing real estate. If the wing end plate is too close to the outer edge of the bodywork, the closed wing design may not efficiently flow air. The leading edge of the front fairing will also get shorter.
Ducati and KTM will probably figure something out, but if they need to change aero strategy that development could factor into the championship during the next 2 seasons. I guess it will depend on how testing goes.
Wish I could remember where I read these thoughts. Social media is making it difficult to catalog sources. It's there for a blink of an eye. If you don't take a screen shot or like it or something, it vanishes into the black hole algorithmic non-recall. Anyway, thoughts are not my own.
