Ducati GP19 swingarm attachment
Peter Bom: The now (in)famous aerodynamic modification on the Ducati, which they claim channels extra air onto the rear tire, which keeps it cooler and improves performance. Since its introduction, we have also seen a similar device on the Honda RC213V, and we expect to see more at Jerez.
Ducati “triple winglet” fairing on the Desmosedici GP19
Peter Bom: A tri-plane winglet arrangement must have quite a lot of horizontal surface area. By spreading that surface area over three wings, Ducati also reduces the risk of damage in case of contact with other bikes. Bikes with as much aero as the Ducati can barely be ridden at all without it any longer.

New Honda fairing (Crutchlow’s RC213V)
Peter Bom: With all the extra horsepower which Honda has this year, together with a different chassis (to take some of the load from the front tire), it would make sense that there could be another aero update as well. As a side note, Ducati Corse boss Gigi Dall'Igna has hinted at protesting this particular fairing design.
