In Spain right now, an assembly of Ducati Corse technicians, mechanics, and riders are tucking into bed after completing the first of three days of MotoGP testing at the Spanish track. After failing to debut its new Ducati Desmosedici GP12 at the 2012 Wrooom media event, Ducati Corse is holding some very private tests at Jerez to sort out the GP12 before Valentino Rossi and Nicky Hayden ride the 1,000cc format machine at the Sepang test at the end of the month. Details about the Desmosedici GP12 have been sparse, though Ducati Corse General Manager Filippo Preziosi did let it be known that the 2012 Desmo was 90% new in its design.

With the 2011 MotoGP season concluding in Valencia this weekend, the 2012 MotoGP season got underway with its first testing session, also held at the Spanish track. A glimpse into the re-established 1,000cc era, perhaps the most anticipated unveiling was Ducati Corse’s aluminum perimeter-style frame, dubbed the GP0. Just one step in the long process of addressing the Ducati Desmosedici’s front-end feeling problem, Ducati Corse’s latest incarnation of a MotoGP chassis has been rumored for some time now.

With all eyes in the GP paddock looking to see if a the conventional frame design would be the silver bullet to Ducati’s woes, the testing sessions in Valencia have been interesting to say the least. With everyone playing Monday Morning Pit Boss over Ducati Corse’s issues, the past two days of tests have been important for Ducati Corse to understand the issues inherent in their design, as well as establishing what the teams does, and does not, know.

According to both GPone and MCN, Valentino Rossi and Ducati Corse will test a new aluminum frame at Jerez this week. Though the two MotoGP authorities differ on what sot of frame exactly will be used during the test (MCN says twin-spar, while GPone maintains an “open cradle” frame that leaves the motor still as a stressed object). Regardless of the style, the new chassis is reportedly made by FTR, and is another attempt by the Italian racing team to figure out how to solve the vague front-end feeling coming from the Ducati Desmosedici GP11/GP11.1/GP12.

Possibly similar to the chassis style used by Honda and Yamaha, this new frame design marks the fourth major chassis change this year for Ducati. Unable to compete against the top pack on the grid, Rossi has lately even struggled to keep up with his fellow Ducati riders come race day. While technically considered a test for the 2012 season and on the GP12 motorcycle, the results from the Jerez test (Ducati’s seventh test of an allowed eight) could easily find its way onto this season’s Desmosedici.

While Ducati might not be getting a two-wheel drive system in MotoGP anytime soon, the Italians are apparently in the process of running a parallel program to its MotoGP racing effort that explores the concept of Ducati Corse switching to an aluminum twin-spar frame. Uncovered by French journalist Thomas Baujard of the French magazine Moto Journal (yes, we really wanted to make sure you knew the French were involved with this), Ducati Corse has apparently enlisted the help of a third-party chassis manufacturing and engineering firm to construct a prototype aluminum chassis.

This news plays into the fact that Ducati has absolutely no experience in making an aluminum twin-spar frame, having dropped the steel trellis design for an all carbon fiber version back in 2009. Not wanting to start from zero, like Corse did with the carbon chassis in 2009, and with the “frameless” chassis in 2010, Ducati hopes that with aid from a third party, the Italian company can come up to speed on the twin-spar design, and begin to make improvements for the GP11/GP12 for Valentino Rossi and Nicky Hayden.

Head of Ducati Corse, Filippo Preziosi is a busy man under regular circumstances, and with the shenanigans going on in Ducati Corse’s MotoGP team right now, the former motorcycle racer is a hard man to get a word with, let alone on a race weekend in Brno. Somehow catching up with Preziosi during MotoGP’s Brno test, our friend David Emmett at MotoMatters, along with several other journalists, sat down with Ducati’s Maestro of MotoGP to ask him about where the Italian team was headed, and the challenges it is currently facing.

There is of course a tremendous amount of chatter going on in the MotoGP paddock about Ducati’s “frameless” carbon fiber chassis, a switch to an aluminum twin-spar frame, the Bridgestone tires, and Valentino Rossi’s psyche, all of which Emmett has already summarized for us in his detailed analysis of Ducati Corse’s situation. Taking on all of these issues, Preziosi sheds some insight on what is going on behind the scenes at Ducati, and is candid about what issues they are and are not facing.

Dismissing out right that the “L” engine configuration is at least partially to blame for Desmosedici’s lack of front-end feel, one of the more interesting points Preziosi makes is his preference for the v-twin motor. Acknowledging that the package will perhaps make less power/torque than a four-cylinder, Preziosi opts for instead the two-cylinder’s rideability, and if the rules allowed it, the motor’s weight advantage over the inlines (this of course coming from a man who has figured out how to make a v-twin without the weight of a traditional frame).

His comments raise some interesting thoughts about the way rules are constructed in motorcycle racing classes, and perhaps speaks to the central issue occurring MotoGP: that the rules are pigeonholing the development of GP motorcycles into one particular slot, that just happens to be a four-cylinder motorcycle with a conventional frame that reacts to a prescribed tire construction methodology. Preziosi makes some other interesting comments that read well between the lines, check them out in transcribed interview after the jump.
