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.

Aside from one or two suspiciously similar motorcycles a year, we don’t often hear from the Italian brand of Bimota. Known for building exotic motorcycles that feature custom frames around production motors (now, what does that sound like?), Bimota used to sample the best engines from all the manufacturers, but lately the motorcycle company seems to favor almost exclusively another certain Italian company in Bologna.

There was also a point in time where Bimota raced its designs, helping the small firm earn a reputation not only for its aesthetic graces, but also for its technical prowess. Hoping to return to its roots with that latter element, Bimota was caught on the track in Spain recently. Testing at the Almeria track, Ruben Xaus (yes, that Ruben Xaus) has settled into his new job as Bimota’s Sporting Director quite nicely.

Xaus is helping the small Italian company improve upon its Bimota HB4 Moto2 bike and Bimota DB8 Superbike. With this testing, Bimota is teasing the possibility of the Ducati 1198-powered Bimota DB8 making a World Superbike wild card appearance for the 2012 season.

Likely to be marked as the start of significant chapter in MotoGP history, the claiming rule teams (CRTs) were out in Jerez the past three days testing their MotoGP machinery, which is comprised of production-motorcycle motors with custom-built chassis. While not the first time we’ve seen a CRT bike on the track, the outing was the first time that  a”top-tier” rider was on-board the new racing format motorcycles, as Colin Edwards lead the charge with his BMW/Suter machine with NGM Forward Racing.

Many in the MotoGP paddock have been waiting to cast their verdict on the CRT endeavor, withholding their judgments until a top GP rider took to the helm of a CRT machine and properly put the bike through its paces. With tests earlier in the year showing Mika Kallio on-board the BMW/Suter to be over six seconds off the pace of the 800cc-era machines, the CRT future of MotoGP looked to be in jeopardy. Those lap times improved over the year to be “only” four seconds off that 1,000-era bike pace, showing improvement, yet a gap  to the front-runners.

Now with Edwards finally swinging a leg over the BMW S1000RR-powered Suter prototype, surely more comparisons between the factory prototypes and CRT offerings are to ensue. Posting a best lap time of 1’40.188 at the Spanish GP earlier this year, Edwards was roughly 2.5 seconds off his own pace, finishing the three-day test with a best lap to f 1’42.6. That news seems discouraging on its face, though it should be noted that the team dropped 1.3 seconds between Wednesday and Thursday’s tests.

Edwards also rated the bike at about 65% of its potential, while the Texan’s own fitness was questionable, as Edwards was till recovering from the injuries he sustained at the Malaysian GP. WIth all those caveat, does this week’s test equate to excuses for a lackluster performance, or justify that more leaps and gains will be made before the start of the 2012 MotoGP Championship?

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.

UPDATE: Álvaro Bautista has signed with the San Carlo Honda Gresini team for the 2012 MotoGP season. The Spaniard is not expect to have a factory support within the team.

Rizla Suzuki has announced today that rider Álvaro Bautista has left the factory Suzuki team for the 2012 season. It has not been announced where Bautista will race next next year, though best guesses would peg the Spaniard as headed to the LCR Honda squad. Certainly linked to this news, Randy de Puniet was given the opportunity to test the 2011 Rizla Suzuki GSV-R yesterday, and the Frenchman has already made some impressions.

Fourth fastest on yesterday’s time sheets, de Puniet has been keen to get out of the Pramac Ducati garage, and onto a more competitive package. With Bautista, de Puniet, and John Hopkins all playing musical chairs around LCR Honda and Rizla Suzuki, Bautista’s departure at least progresses the game forward. The big question still remains though, with Bautista leaving the Rizla Suzuki squad, does that signal another rider’s entry into the factory team, or does it mean the Japanese company’s departure from MotoGP racing?

After a somber tribute to Marco Simoncelli, racing at Valencia commenced Sunday under ominous skies. While the weather has been variable throughout the Valencian GP, Sunday’s forecast was especially treacherous, as the off-and-on drizzle was neither damp enough for a full-wet setup, nor dry enough for race slicks. Nothing better highlighted this fact than a blitzkrieg lap by American Josh Hayes, which saw the AMA Superbike Champion on slicks dust the rest of the rain-shod MotoGP field by three seconds on the closing Warm-up Session lap.

With the wetter weather favoring the struggling Ducatis of Nicky Hayden and Valentino Rossi, the chance of rain equated to a chance for a Ducati Corse podium. The RC212V of Casey Stoner of course stands in their way as always, as does the Repsol Honda of Dani Pedrosa. Also fast this race weekend has been Alvaro Bautista, the Spaniard surely encouraged by a local crowd, as well as the prospect that his results in Valencia could help sway a very reluctant Japanese management into racing in MotoGP next year.

Randy de Puniet is also worth mentioning, as the Frenchman has been one of the fastest Ducatis all weekend, and missed a front-row start by only .06 seconds. With four manufacturers starting in the top five grid spots, the 2011 MotoGP Championship and the era of 800cc GP bikes, concluded with some of the most diversity it has ever seen on starting line.
