The BBC Sport MotoGP team: Parrish, Perry & Cox
This year BBC Sport will be bringing you our most comprehensive coverage of MotoGP yet.
Suzi Perry will be at every race this season, and she answered your questions on Wednesday 1 June.
Valentino Rossi has once again led from the front, winning three of the first four races of the season.
And his position at the top looks secure with Sete Gibernau failing to make an impact, and Max Biaggi looking a shadow of his former self.
Thanks for all your questions - here are a selection of the best.
Qu: With Sete not putting up a proper challenge so far this year, it looks like Rossi will win again (which incidentally is completely fair, because he is the best).
What is the feeling about Sete in the pits? Will his time in MotoGP soon be up? There's only so long you can go on without winning titles, and Melandri would seem to be the only racer who has the ability to take Rossi's crown...at least until Pedrosa arrives in GP
Justin Cleator, Luxembourg
SP: I think the feeling in the pits is that Sete has made massive improvements to his riding style over the last year. Admittedly he hasn't started well this year but I think that he is still Valentino's biggest threat out there - I think we are yet to see the best of Sete.
As for Melandri, he has amazing potential but he won't win a World Championship while Valentino is still in MotoGP.
Qu: Do you think that James Toseland's disappointing start to the season in World Superbikes, apart from his win at Silverstone, has harmed his chances of picking up a decent ride in Moto GP next year?
Britain doesn't have a top GP rider on a top bike. Is James good enough for GP's do you think?
Jon Day, England
SP: I'm not sure there was any deal on the table for James to join MotoGP this or next year, so his performance over the past few weeks hasn't scuppered any deal as such.
It's very difficult for riders to get into MotoGP - the chances are few and far between - and who's to say James is even top of the list of the guys waiting for their chance?
I think Chris Vermeulen is probably in pole position as far as that particular race is concerned.
Two World Championships in a row would look good on the CV, but I think he'll struggle to beat the Suzuki - I'm not saying he can't do it, it's just unlikely.
Qu: Do you feel Valentino Rossi would be successful in F1 if he went ahead with the rumoured switch of disciplines?
Jon Bellwood, UK
SP: I think it's unlikely that Valentino will jump straight to F1, and as far as I'm aware there are no deals on the table from anyone - I suppose there could be an opening at Red Bull but it's all hypothetical.
Another factor you have to take into account is that Valentino is actually quite tall, and not the right height for a F1 driver.
I know he's a big fan of rallying and if he were to move anywhere I think it would be to that. All I would say is that he's one of these characters who are successful whatever they do.
Qu: Hi Suzi, following Neil Hodgson's disappointing season last year can you see a Brit challenging Valentino on a competitive bike in the near future and if so who?
Jason Stredwick, UK
SP: No! There isn't going to be a Brit on a competitive bike in time to challenge Valentino. We've only got two more years of the Italian and it's not going to happen.
It would be good if Shane Byrne was offered a good ride but there are no signs of that happening at the moment.
Qu: If you could have a pillion ride around a circuit with one of the GP guys, which rider and bike would you choose?
Andy , England
SP: Ducati are the only manufacturers I know of who have a two-seat MotoGP bike - I flew round Donnington on one last year!
But hypothetically it would have to be with Valentino Rossi on the Yamaha M1 around Mugello.
Qu: I think this is Nicky Hayden's third year in MotoGP on the works Honda - why isn't he making more of an impact ?
Nick McCarthy, UK
SP: Good question - I don't know. He is a very talented rider but everyone has been disappointed with his performances - not least himself.
Nicky is a young guy but he knows he has to start getting results, otherwise the Repsol team will find someone else.
Qu: Hi Suzi, how would you explain Max Biaggi's relatively poor performances? Is it purely down to him, or are there circumstances that I'm not aware of?
Christian Tiburtius, Reading
SP: I think the problems with Max are 99% psychological. That is the sort of person he is. Max is a very clinical rider and everything has to be perfect if he is to perform.
The trouble is that he is now on the dream bike in a dream team, so the excuses are running out. This weekend's race at Mugello will be key - it's a circuit he likes and has done well on.
If he can't pull it together at home then his days will be numbered.
Qu: How much of a blow you think it would be to Moto GP as a sport if Rossi were to leave at the end of next season? After all, he is the ultimate competitor at the moment, surely the sport would lose some of its popularity?
SP: I have a huge amount of respect for Valentino - he is an amazing talent and we have all enjoyed watching him grow over the past 10 years.
I think it is inevitable that he will leave at the end of next season - he will have achieved everything there is to achieve in MotoGP.
When he goes there will be a huge gap to fill - a vacuum - and that first season will be slightly odd, as he is such a big character. It will be up to his fellow riders to step up and do their best.
Thanks for all your questions - and remember that we're live this Sunday at 1235 on BBC Two with coverage from Mugello, and that you can catch qualifying in Italy on Saturday, BBCi at 1255.
