MotoGP fans have been rubbing their hands in anticipation of this weekend’s final round of the championship. The race has everything: a mental Moto3 race to be decided outright by the rider who wins, with just five points separating Luis Salom, Maverick Viñales, and Alex Rins.

There is the triumphant homecoming for a newly crowned Moto2 champion, Pol Espargaro wearing a positively regal helmet to celebrate, while his title rival Scott Redding wears special leathers and helmet thanking the Marc VDS Racing team who have stood behind him for the past four seasons

And then there is the shootout for the MotoGP championship, between Jorge Lorenzo, a man with nothing to lose, and Marc Marquez, who has to balance between riding hard enough to keep the bike working properly and not taking any unnecessary risks, while ensuring he comes home in fourth, something which sounds easier than it is.

There were even a couple of sideshows: the presentation of the Honda RCV1000R production racer, and Yamaha’s annual technical presentation, in which they brief the media on how they have developed the bike to be so competitive.

All that is forgotten. Valentino Rossi’s shock announcement on Thursday that he had told long-term crew chief Jeremy Burgess that he wanted to replace him with someone else has dominated the headlines, as well as the hearts and minds of almost everyone in the paddock. In the search for the elusive last couple of tenths of a second which separate Rossi from the three Spanish superstars who have dominated the 2013 season, the Italian is leaving no stone unturned.
