The unprecedented delay to the MotoGP World Championship also means the sport's biggest ever star, Valentino Rossi, faces a more complicated decision on his racing future.

The nine-time world champion aimed to spend most of the opening half of this season analysing his competitiveness at a range of circuits before either opting to retire or switching to a satellite Yamaha in 2021.

Instead, the coronavirus means Rossi and his MotoGP rivals haven't completed a single race this year and are still months away, at best, from being back on the grid.

"I hope that we start racing as soon as possible, so that he has time to decide," Rossi's Monster Yamaha team director Massimo Meregalli told engine and aerodynamic development until the end of 2021 revealed by yesterday:

"In my opinion it is a fair decision if it will be carried out, given the situation it seems to me an excellent solution."
