Making a full livery takes time and effort . Also , this are huge companies , they don ' t just fit the decals wherever they want , it ' s probably a whole process talk to the designers , who talk to marketing , who double check with the customer , then send the prints , get the technicians to plot them , then get the designers to approve the final result , etc , etc . . Since this are new bikes , that are changing constantly , going through all that each time doesn ' t really make sense , specially since they won ' t get much exposure . Even in the official test , there won ' t be but a handful of people . In any case , it ' s not even the 100 k people at the track the sponsors care about the most , it ' s the millions watching it on TV that they pay for . In some cases , they can ' t really even show any sponsors , because the riders are switching teams and they are not cleared to have those sponsors they are still under contract with the previous team and its sponsors until the end of the year .
