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?

The Selection Committe, comprised of the FIM, IRTA, and Dorna, has released its official list of entrants for the 2012 Moto2 & Moto3 World Championships. Subject still to the final confirmation of riders contracted to the teams, we can initially see that Moto2 will get a slight grid reduction for 2012, as the middle-child of Grand Prix racing will have 32 riders from 20 teams competing on any given Sunday.

That number will also hold for the new Moto3 class, which will replace 125GP in the upcoming season. Notable team entries come from Bankia Aspar, which is currently leading the 125GP class, and Gresini Racing, which will have a stake in each of the three GP classes. Also present is Marc Marquez’s Monlau Competicion team, which adds some fodder to the increasing debate as to whether the talented Spaniard will ride in MotoGP for next season, though we expect to hear more on that at Valencia, if not at Sepang.

Though an official list, a final selection meeting will be held by the Selection Committee at the Valencia GP, after which a final list of teams and riders accepted will be published. Check the official Moto2 & Moto3 entries after the jump.

Two-stroke racing has been living in a four-stroke world, and the death blow to the smokers in GP racing has already been dealt by the GP Racing Commission. With 2012 set to see Moto3 replace 125GP as MotoGP’s introductory class, the FIM has released the full technical specifications of the up-coming, 2500cc, single-cylinder, four-stroke racing class. Designed not only to bring GP racing into the 21st century, Moto3 also aims to end the Aprilia domination that’s currently taking place in the class’s two-stroke predecessor. With companies like Honda and KTM building complete Moto3 machines, and engineering firms like Kalex working on custom chassis for the prototype 250cc engines, there certainly looks to be a bit of diversity coming to the introductory GP series.

Another issue plaguing 125GP, and GP racing as a whole, is the rising costs of competing in the sport, as evidenced by the diminishing grid size in MotoGP. With Moto2 boasting a healthy 40 bike grid, Dorna and IRTA believe they have found the secret recipe to making prototype racing work, and have applied that methodology to the new Moto3 class. Unsurprisingly then, the vast majority of Moto3′s technical regulations concern keeping costs down, especially when it comes to the series’ claiming-rule style engine & parts restrictions. It’s actually interesting to read the level of detail the GP Commission has gone through in order to head-off attempts to circumnavigate the spirit of the cheaper four-stroke series, though we might point out that water always finds its level.

Despite the criticisms from GP riders, the Indianapolis GP has been renewed on the MotoGP calendar through the 2014 season. With Dorna keen on having a larger US presence, and the Indianapolis Motor Speedway wanting to continue to host the premier classes of motorcycle racing, the biggest issue for the contract’s renewal (besides tarmac conditions), was the scheduling involved with IMS, Laguna Seca, and MotoGP.

Wanting to have the two US GP rounds back-to-back, Dorna faced two circuits with very inflexible summer schedules. Able to now schedule the Indianapolis GP for August 17th-19th in 2012, the Indy GP has effectively been moved a week earlier in the year, and will likely follow the Laguna Seca GP in 2012, with Brno to follow afterwards.

Nicky Hayden was at the Indianapolis Motor Speedway this weekend, checking out the newly repaved infield section on the historic American track. Testing the track on a Ducati Superbike 1198SP, Hayden took a number of laps before giving the nod that he approved of the refurbishment (the FIM also gave their nod on Indy’s work on July 7th). The repaving of the infield portion of the circuit, Turn 5 through Turn 16, comes as a response from riders’ complaints from last year.

With several varieties of pavement, a bevy of bumps, and some poorly placed drainage components, the Indianapolis GP has been a low-point on the MotoGP calendar for most of the MotoGP paddock the past few years, despite being held at an otherwise top-rate and historic venue. With Dorna likely pressuring Indianapolis into making alterations, the track probably faced compulsion to make changes to its infield, especially with the Circuit of Americas track currently being built in Austin.

Talk in the MotoGP paddock is that the Austin GP is now being aimed as less of a replacement for the Indianapolis GP, and instead will be a third stop in America for MotoGP, as Dorna wants to expand the premier class’s presence in the USA. With the 2011 Indianapolis GP just two and a half weeks away, all the GP riders will soon get to see the improvements at Indy, until then they’ll just have to take Nicky Hayden’s word on it. A brief Q&A with the Kentucky Kid and video of his laps and thoughts are after the jump.

The FIM’s preliminary report on the safety concerning the Twin Rings Circuit at Motegi was announced after the conclusion of the US GP at Laguna Seca this week, and confirming what many had already expected, the study concludes that it is safe for the MotoGP riders to go race at the upcoming Japanese GP. Showing that there were no health concerns from radiation in and around the Motegi circuit, Dorna has said it will formally announce its intention to hold the Japanese GP as planned, with its rescheduled time in early October.
