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.

Crashing hard in the Malaysian GP, it initially seemed that Ben Spies had escaped serious injury, as the Clinica Mobile staff gave the American rider a clean bill of health at the circuit. Getting examined further in Kuala Lumpur however, it became apparent that Spies had suffered quite a number of injuries – an AC shoulder separation, a cracked rib in the upper-chest area, and bruising to his lung, to be precise.

Undergoing surgery today at the National Surgery Center near San Jose, California, Spies reported on Twitter that the operation had gone well, though the extent of his injuries will mean an increase in the duration of his recovery time, with 10 to 12 weeks being the number banded about. This news means that Spies will miss not only the Australian GP, but also the Valencian GP and the post-season MotoGP testing — a serious blow to the soon-to-be Ducati rider.

As if crashing out of the Malaysian GP wasn’t bizarro enough, Ben Spies has announced today that he will be missing the Australian GP, as it has become evident that he injured his shoulder in his wet-weather tumble at Sepang. Although found to have no injuries by the Clinica Mobile staff at the circuit, after undergoing tests in Kuala Lumpur post-race, Spies found that he had sustained an AC shoulder separation, a cracked rib in the upper-chest area, and bruising to his lung.

Returning to the US for treatment on Tuesday, Spies will accordingly miss the MotoGP’s next stop, which is at Phillip Island. His participation in the last round of the season, the Valencian GP, is now in question as well, though it could be possible for the American to be healed enough to race within that time frame.

Though this season has been a string of highly suspicious instances of bad luck for the factory Yamaha rider, Valencia will be important round for Spies, as the post-race test will be the first opportunity for him to ride the Ducati Desmosedici race bike.

As was forecasted, the rain made its appearance for the start of the Malaysian GP being held at Sepang. The wet weather of course meant all bets were off for what could happen on this third-to-last round in the MotoGP Championship, and the adverse conditions increased the possibility of some “off-road excursions” by the riders. No one had more to lost from such a proposition than current points leader Jorge Lorenzo.

Sitting 28 points ahead of Dani Pedrosa, the factory Yamaha rider needed only to stay upright on his machine to retain control of the 2012 MotoGP Championship title, but with the rain in Sepang, that simple task could prove to be more difficult than anyone imagined. Needing to grab back as many points as possible, no one probably welcomed the rain more than Dani Pedrosa…well, except maybe the Ducati riders, which made for some high-stakes in the otherwise low-action race

One of the three “flyaway” races before the season finale in Valencia, the Japanese GP is race that is not only important to the two remaining Japanese manufacturers in the premier class, but it begins the dénouement of the MotoGP Championship.

Finding renewed vigor in his Championship hunt, Dani Pedrosa has only a handful of races left to catch Jorge Lorenzo, and win his first premier-class title. Truthfully needing Lorenzo to make a critical mistake or suffer a mechanical failure, Pedrosa also has to keep the pressure on his rival, and try to minimize the gap to his fellow Spaniard.

With each place separating the two riders likely to play a pivotal role at the end of the season, the drama unfolding in Motegi was palpable, though the action itself was a slow grind of a multi-campaign war.

There is little that motorcycle racing fans more than a good conspiracy. No mishap, contract dispute, or rider swap is ever the result of chance, error, greed or incompetence; there are always darker and greater powers involved, be it Dorna, Honda, or a major sponsor. They do not let the fact that their theories bear little resemblance to reality in 99.999% of the cases spoil the fun, and rightly so, moving happily on to the next dark conspiracy.

It took less than 10 minutes of the first session of MotoGP free practice before they had plenty to get their teeth into. Casey Stoner barely made it out of the pits before his Honda RC213V packed up, and he was forced to park it up by the side of the track, the bike felled by a mystery electronics issue. Stoner lost a lot of time in that first session, working with just a single bike as his mechanics tried to find out what had caused his first bike to fail. In the afternoon, an issue with the brake caused Stoner similar problems, losing valuable track time he needs to get back up to speed again.

A plot to prevent Stoner from interfering with Dani Pedrosa’s shot at the title? An entertaining idea, but in the reality stakes, somewhere beyond the moon landings conspiracy. Stoner’s problems are the kind of issue that every team has from time to time, with minor technical issues conspiring to work against them.

Ducati Corse director and Ducati’s engineering guru Filippo Preziosi was a busy man at Misano. Besides overseeing the race weekend at the circuit and preparing for the test on Monday, Preziosi spent a lot of time talking to a number of journalists. I was one of the lucky few who were offered ten minutes with Preziosi, and so I jumped at the chance.

In the interview, Preziosi covered a number of topics: the Ducati junior team strategy, Ducati’s four riders for 2013, the current and expected developments for next season were all among the subjects discussed. Preziosi also talked about the effect of the spec ECU, which will be introduced for 2014, and gave the impression he was not necessarily opposed to the idea. After the jump is what Preziosi had to say.

Even before the lights could go out to start the San Marino GP, the pre-race drama for MotoGP fans was intense. Stalling on the starting grid after the riders’ sighting lap, Karel Abraham raised his arm to signal the dangerous race conditions. Virtually a moment away from the start of the race, the yellow flags of the marshals flew, and the start was aborted — though, the confusion didn’t stop some riders from rocketing off the line. Thankfully however, the situation was without incident.

With a number of bikes needing to be restarted because of the failed start, teams and mechanics again filled the grid, and the start of MotoGP’s visit to Misano was delayed. No one was more affected by the restart than pole-sitter Dani Pedrosa, whose Honda RC213V had its front wheel locked-up when the team attempted to take off the tire warmers for the race’s restart. With the one-minute horn sounding, the Repsol Honda mechanics had exceeded their amount of time to work on the bike, though the situation was resolved in time for Pedrosa was able to join the field for the sighting lap.

Noticeably shaken by the incidents that occurred just a moment from the lap, and running on essentially cold tires, Pedrosa was lapped by the pace car, and ultimately had to start the San Marino not on pole, but instead at the back of the grid. Yes, even before the race started, the San Marino GP proved to be one of the most dramatic rounds of the 2012 MotoGP Championship.

Not too hot, not to cold…that’s Misano for Saturday’s qualifying event. After seeing Friday’s FP1 & FP2 sessions obliterated by a damp, but not wet, track, MotoGP riders found things for Saturday to be just right. The first chance for Jonathan Rea to get a proper go at the Honda RC213V, the Honda WSBK rider is merely “filling in” for the injured Casey Stoner, but many in the paddock believe that a good showing from Rea could land him on the Honda Gresini machine for next year — the last prototype seat in MotoGP still available.

While we will undoubtedly have to wait a bit longer to see that seat filled and sorted, the big attention for the day was the battle between the two Spaniards, as Dani Pedrosa is running out of rounds to catch up to rival Jorge Lorenzo in the Championship. Needing a win this weekend to keep those hopes alive, many GP fans are hoping for another battle between the two riders, like the one we recently saw in Brno. If the qualifying session is any proof of the matter, racing on Sunday should be quite good.

The return to Misano was always going to be an emotional affair, the first time MotoGP has returned to Marco Simoncelli’s home circuit – now renamed in his honor – since the Italian fan favorite was killed in a tragic accident at Sepang last October. Though Simoncelli is being remembered in many different ways during the weekend – nearly all of the riders in all three classes joined for a lap of the track by bicycle this evening – the remembrance has been cheerful rather than mawkish, a celebration of his life rather than mourning at his death.

Fans, riders, mechanics, photographers, journalists, many have made the pilgrimage to Coriano, Simoncelli’s home town just a few short miles from the track, paid their respects and headed to the circuit feeling better for the experience. Simoncelli’s ghost may haunt the paddock at Misano, but happily, he does so in the guise of Casper rather than Banquo.

There is more than enough to keep the minds of those present engaged. Uppermost in most people’s thoughts is Ben Spies’ decision to go to Ducati to race in the Ducati junior team that is to be run by Pramac. Both of the 2013 factory Ducati riders welcomed the signing of both Spies and Andrea Iannone, with Andrea Dovizioso and Nicky Hayden saying it was a good decision by Ducati.

Both Spies and Iannone had proven their speed, and Spies’ experience at the factory Yamaha team would be very valuable to Ducati in helping to develop the bike. There was surprise at Spies’ decision – “I thought he would go to World Superbikes” Dovizioso told reporters – and both men were interested to see how he would perform on the Ducati.
