Andrea Dovizioso is expecting the unexpected during MotoGP's debut in Thailand this weekend.

While Dovizioso narrowly lost out to Marc Marquez last time in Aragon, it was by far the Italian's best performance at what has traditionally been one of his worst circuits.

It also gave the reigning title runner-up a 15-point lead over Valentino Rossi and 44-point advantage over team-mate Jorge Lorenzo in the fight for second in this year's world championship.

Dovizioso was seventh fastest but just 0.4s from the top during February's ultra-close official test at Buriram, when - in stark contrast to team-mate Jorge Lorenzo - he appeared content with his set-up for both a single lap and race pace.

However the use of revised Michelin rear tyres for the race weekend creates some added uncertainty.

“The Buriram track is very strange and we have never raced there so it will be a totally new situation for everyone," Dovizioso said.

"In the tests in February here in Thailand we didn’t do too badly at all, but now I think that we are much more competitive than what we were at the start of the season.

"We’ll have to see what the conditions are like because it might be hotter than in Malaysia and this will surely affect the race, but above all it looks like we’re already in the rainy season, so everything can happen.”
