The atmosphere in the paddock at Valencia is an odd mixture of fatigue, excitement and anticipation. Fatigue, because it is the end of a long season, and the teams and riders are barely recovered from the three back-to-back flyaway rounds; excitement, because this is the last race of the year, and the last chance to shine, and for some, the last chance to impress a team sufficiently to secure a ride next year; and anticipation, because with so many riders switching brands and classes, they are already thinking about the test to come on Tuesday.

Or in Casey Stoner’s case, thinking about a future outside of MotoGP. As his departure from the championship grows near, it is clear that he has had more than enough of the series. Asked if he was worried about the politics in V8 Supercars, where he is headed in the near future, he said he wasn’t, because he understood that V8 Supercars is a different kind of championship.

MotoGP, though, was supposed to be a professional championship, and in his opinion, it was ‘a joke’. Four races in Spain, another just over the border in Portugal, this was not a truly world championship, Stoner said. Instead, MotoGP is too much of a European championship, and it needed to rediscover its roots.

In an ideal world, championships are settled in a straight fight between the main contenders in the final race of the season. Unfortunately, the world we live in is far from ideal – as the ever-dwindling stock of prototype machines on the grid testifies – and so the last race of the year can be a bit of a formality. In 2012, with the champions in all three classes securing their titles during the flyaways, there is not much more at stake at Valencia. Except pride.

Given that pride is what motivates a motorcycle racer above all else, that means that there is every reason to hope for a real treat at Valencia on Sunday. This is the last race of the season, the last chance to prove your worth, to silence your doubters, to settle those scores before the long winter begins.

No need to be conservative here, no need to calculate the odds. You can take that chance, take a risk and crash out trying. At the last race of the season, you go all in, as Nicky Hayden’s leathers proclaimed at Valencia in 2006, when it looked like he might miss out on his first ever MotoGP title. And there is a lot of pride at stake.

With all three world titles settled as we head to Valencia, some find their attention more focussed on the test that follows the season’s final round, rather than on who will win any of the weekend’s three races.

Certainly Rossi’s future reunited with Yamaha and Jorge Lorenzo as teammate is a subject of great interest, as is Marc Marquez on a factory Honda. But also there’s the future of Ducati to ponder, as a returning Nicky Hayden is joined by Andrea Dovizioso, while Ben Spies and Andrea Iannone join up to ride for the factory’s junior team.

Here are four gifted riders with several world championships between them. But as good as they are, none of them is Casey Stoner. And none of them has the financial backing of Valentino Rossi, who was able to ask for major changes to the GP11 and GP12 designs, none of which resulted in a package that would allow Rossi to return to the front of the pack.

With the news that the injured Ben Spies would miss not only the Australian GP, but the Valencian GP as well, the American MotoGP rider’s miserable MotoGP season was abruptly ended after his fall at Sepang.

Set to ride on the Ducati Junior Team next season, Spies’ run with Yamaha now seems to have concluded, and the attention has shifted as to whom would ride in his place at Valencia, if anyone.

Despite a twitter campagin to get American Josh Hayes back on a Yamaha YZR-M1, Yamaha Racing have instead chosen test rider Katsuyuki Nakasuga to replace Ben Spies on the factory Yamaha.

Ever since Jorge Lorenzo’s #3 engine went up in smoke at Assen, after the Factory Yamaha man was scuttled by Alvaro Bautista in the first corner, MotoGP followers have been asking themselves whether Jorge Lorenzo will make it to the end of the season with the remainder of his allocation, or whether he will have to take a 7th engine and start from pit lane at some point.

As each race goes by, the questions have become more urgent: will this be the race where Lorenzo finally runs out of engines, and hands Dani Pedrosa the advantage in the championship fight?

So how is Jorge Lorenzo doing with his engines? Is he, as many suspect, in imminent danger of losing an engine, and with it potentially his second World Championship? What strategies have his pit crew been using to manage with one engine prematurely withdrawn? And will those strategies be enough to see him through to the race at Valencia?

Jerez is to remain on the MotoGP calendar for at least one more year. Dorna CEO Carmelo Ezpeleta announced the extension during the official presentation in Madrid of this year’s Spanish GP at the iconic Jerez circuit, stating that Jerez will stay on the calendar for 2013. He also confirmed that from next year, there will be just 3 races on the Iberian peninsula (Spain and Portugal), with Jerez and Aragon certain to stay, while Barcelona and Valencia could alternate, as is currently being proposed for Formula 1. Meanwhile, the Portuguese Grand Prix at Estoril appears destined to disappear from the calendar.

Rumors surrounding the fate of the Jerez Grand Prix had been circulating for a while, with the circuit still in financial problems over non-payment of debts to the consortium that carried out remodelling work at the circuit back in 2001. It was widely expected that Jerez would be dropped from the calendar, but sources close to the circuit owners were confident of being able to continue. Though the official confirmation is only for 2013, the chances of the race remaining at the track for the next five years look very good.

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.

With every bike from the three GP classes out on the Circuit de Comunitat Valenciana, the sight was one that had to be seen in person to be truly appreciated. Lead by former-World Champion Kevin Schwantz, who rode Marco Simoncelli’s San Carlos Honda Gresini RC212V race bike, MotoGP, Moto2, & 125GP riders made their way around the 14 turns of the Spanish track, stopping short of the finish line. Watching two minutes of Valencian fireworks, MotoGP riders stood with the Simoncelli family, honoring the loved Italian one more time.

The entire event was somber, and as the fireworks subsided, the clamorous noise was contrasted with an eerie silence on the track and in pit lane. Riders walked back to the paddock with solemn & grim faces, barely saying a word to each other, if saying any words at all. Similarly, team members carried rear stands and walked race bikes back to pit lane in complete silence, perhaps reflecting on Marco one more time. Thirty minutes later, noise returned to Valencia, as the final 125GP race ever commenced.
