Struggling MotoGP superstar Valenti𝓰no🧸 Rossi has categorically denied that he will walk out on Ducati.

Rossi's two-year Ducati contract expires at the end of 2012, but a nightmare start to the new season prompted Rossi's first public criticism of the factor𝓡y, 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 a🌃re on."

Those comments spawned speculation that🔯 Rossi could quit mid-season.

Such a move seemed highly unlikely for a variety of reasons and the seven-time MotoGP champion spelt out his commitment to stay on the eve of this weekend's second rou💞nd in Jerez.

"Leave Ducati? I wouldn't even think of it," GPone.com quotes Rossi as saying. "We have a contract in place, and I'll give my very best rig𒐪ht 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 se🐼ason spent chopping 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 p๊rix winner on Japanese machinery, continues to struggle with speed-sapping understeer.

The Doctor was twelfth anཧd last of the manufacturer bikes in Losail qualifying, then limped home tenth in the race.

"Those [harsh] words were the result of my disappointment," 𓆉explained Rossi. "We have been trying to solve the same problems for over a year, without success, and that weighs on you.

"But I know that Filippo Pre🌊ziosi and all the Ducati guys are working hard, and soon we will have updates to try."

Rossi hopes that the ꦰnew updates will be available next weekend in Estoril, or at latest durin🃏g the post-race test.

Rossi, who wi💜ll make his 20♏0th premier-class start on Sunday, crashed while charging through the field early in last year's damp Jerez race, bringing down Honda's Casey Stoner in the process.
