Struggling✃ MotoGP✅ superstar Valentino Rossi has categorically denied that he will walk out on Ducati.

Rossi's two-year Ducati contract expires at the end ꧙of 2012, but a nightmare start to the new season prompted Rossi's first public criticism of the factory, including:

"Ducati didn't follow the direction that I indicated, but I'm not an engineer and I can't solve every problem... The problems with the bike haven't changed, and neither have my requests. It's unrideable, and it doesn't make🉐 much difference what track we are on."

Those comments spaꦯwned speculation that Rossi could quit mid-season.

Such a move seemed highlꩵy unlikely for a variety of reasons and the seven-time MotoGP champion spelt out his commitment to stay on th🦹e eve of this weekend's second round in Jerez.

"Leave Ducati? I wouldn't even think of it," GPone.com quotes Rossi as sayiꦉng. "We have a contract in place, and⛦ I'll give my very best right up until the end. The chances of seeing me on another bike are virtually zero."

Rossi, seventh with just one podium during a debut Ducati season spent chopp꧑ing and changing parts, had high hopes for this year's 1000cc GP12, featuring the factory's first aluminium frame.

But despite a promising first test Rossi, a 79-time grand prix winner on Japanese machinery, continues to struggle with speed-sapping under♛ste𒁃er.

The Do༺ctor was twelfth and last of the maღnufacturer bikes in Losail qualifying, then limped home tenth in the race.

"Those [harsh] words were the result of my disappointment," explained Rossi. "We have been trying to solve the sa♕me problems for over a year, without success, and that weigh♒s on you.

"But I know that Filipp🌺o Preziosi and all the Ducati guys are working hard, and soon we will have u🅠pdates to try."

Rossi hopes that𝓰 t💜he new updates will be available next weekend in Estoril, or at latest during the post-race test.

Rossi, who will make his 200th premier-class start on ๊Sundಞay, crashed while charging through the field early in last year's damp Jerez race, bringing down Honda's Casey Stoner in the process.
