Aero devices have been gaining prevalence in MotoGP ever since Ducati first introduced winglets on its bike in the mid-2010s, with other manufacturers also jumping on the bandwagon after seeing how it transformed the performance of the Desmosedici.
While the impact of excessive aerodynamics on the quality of racing has made its usage a controversial topic, 2024 saw bike makers only taking things up a notch by investing more in radical wings and fairings – with Aprilia and KTM leading the way in terms of new developments.
Miller feels that aero offers a cost-effective method of bringing performance updates to MotoGP bikes and says it is now the last key area that hasn’t been exploited fully by the five manufacturers competing in the premier class.
“It's the main thing,” said the KTM rider. “We have spent so many years developing electronics, engines, tyres and so on and so forth, now we are at the last piece of the puzzle that we can do.
“I saw a quote from somebody at Aprilia saying it's cheaper for them to develop the aero than it is the engine.
"Well, that is true. We don't wanna go and redevelop one of these MotoGP engines, it's crazy. So aero is an easy bolt-on feature that can help.
“But where does it end? Where does it keep going? I don't know."
