Reigning MotoGP World Champion Valentino Rossi has said that choosing to move the Motegi round from the end of the season forward to April wasn't a good idea and that it will be one of the most uncertain races ever.

The Fiat Yamaha rider is hoping that the weather is either wet or dry, and not in between, as the whole grid has only had 45 minutes of practice in either conditions and noneon a drying track.

"I don't think it was such a good idea to come to Motegi in April! So now we're going into a race after just 45 minutes in the dry and 45 minutes in the wet, and I think maybe it will be one of the most uncertain races ever," said The Doctor.

"We're lucky because we had a good session in the dry yesterday and so we're on pole, which is very important for the race here but it's still impossible to be at 100% after such a short time and with so little data. In the dry this morning our setting worked well also so I think we can fight whether it's dry or wet, and after all it's the same for everybody.

"Of course I would prefer it to be dry but above all I hope it's not half and half, I hope it's either fully wet or fully dry otherwise it will be even more difficult."
