The carbon fiber covered chassis on the Honda RC213V test bike used by Stefan Bradl
David Emmett: This was the talk of the Jerez weekend. Stefan Bradl had two bikes at his disposal, this one, featuring a different chassis design (see the scalloped section in the center of the main beam), and the standard aluminum chassis. After Honda spent the winter working on the engine of the RC213V, they are now diverting their attention to the chassis. Riders have complained of a lack of front end feel from the 2019 frame, and this seems to be an experiment to create a bit more feel, especially on corner entry and mid corner. Marc Márquez tested this chassis at Jerez on Monday, and set his fastest time on the bike.

David Emmett: A view of the full frame. The welds appear to be in the same place as the standard frame, but the top beams are different.
