Ducati has confirmed that a substantially revised version of its Desmosedici Mo🌺toGP machine will debut at this weekend's Aragon round.

The changes - believed to include the chassis and engine - will be the biggest since the start of the season and a stepping stone towards new Ducati Corse general manager Gig Dall'Igna's fu🐽ll 2015 re-design, to be seen in testing at Sepang next February.

According to a Ducati statement, Andrea Dovizioso and 2015 factory team-mate Andrea Iannone (currently at Pramac) "were able to shakedown the 'evolution' version of their Desmosedici, called GP14.2, for the first ti💮me" during a private test at Mugello on Tuesday.

"The two Italian riders will continue to test the b𝄹ike during the Arag?n race weekend," the statement added.

The changes will therefore not be made available to Dovizioso's present team-mate Cal Crutch💛low, who is leaving for LCR Hond𝓀a at the end of the season.

Dovizioso is fifth in the world championship,ꦡ with two podiums, and needs just two more points to match his entire 2013 tally.
