Three races into the 2013 MotoGP season, and the Yamaha Factory Racing team have been forced to tear up the script they had written for themselves after pre-season testing. Their original goals were for Jorge Lorenzo to win as often as possible in the early part of the season, building a lead at the tracks at which Yamaha is supposed to be strong, then defend that lead in the second half of the year. Valentino Rossi, meanwhile, was to finish adapting to the Yamaha once again, and get on the podium ahead of the Hondas as much as possible, to help build out Lorenzo’s lead in the championship.

The plan worked perfectly at Qatar. Lorenzo was untouchable in the race, and won easily. Rossi showed he still had it by getting on the podium and taking second, while the first Honda was Marc Marquez in third. This worked out even better than expected, as although Marquez is clearly an exceptional talent, the real title threat, Yamaha believed, would come from Dani Pedrosa.

The MotoGP paddock is assembled in all its splendor at Jerez, and it is positively bulging at the seams. Shiny new hospitality units (very shiny, in the case of the Go&Fun Gresini unit) now pack the paddock, the existing units larger and new units added, causing the paddock to loosen its belt and expand into the adjacent car park, sequestering part of the area previously reserved for team and media cars. Under a bright blue Andalusian sky, it really is looking at its most appealing.

The expanded paddock makes you understand why IRTA decided to ban Moto2 and Moto3 riders from having their motorhomes in the paddock, all of them now expelled. The riders themselves are less impressed. “It was nice to have somewhere you could zone out during the day, and relax,” Scott Redding said of the change. Sitting in the hospitality and watching the world go by was very pleasant, but still left him on his guard, he explained. Private quiet time was gone.

And it also removes part of the socialization process which young riders used to undergo, with the Moto2 and Moto3 men wandering around the paddock chatting to team members and other riders, everyone getting to know each other, and catching up on the latest news and gossip.

It was part of what made the paddock feel like a village; a small Italian village, high in the mountains, with an inexplicably male-dominated population.

The Moto2 and Moto3 riders added much to the fun of the place, spending most of their evenings challenging each other to wheelie competitions on mountain bikes and scooters. The paddock loses much with the change, feeling more like a workplace than a community.

Despite the loss of teenage hooligans trying to outdo each other at various two (and one) wheeled contests, there is a real buzz in the paddock. The race is shaping up to be one of the most interesting in a very long time, possibly one of the best races of the season. The reason is simple: this is a track which, though it favors the Yamaha, the Honda can compete as well.

“I thought Laguna Seca was a tough track to learn, and then I came here.” Bradley Smith’s verdict on the Circuit of the Americas at Austin, Texas, after six laps on the scooter around the track.

Smith’s words sum up the general feeling about the newest addition to the MotoGP calendar, mind-boggling sequence of decreasing and increasing radius turns, with blind entrances, complex combinations and a few hard-braking hairpins with tough entrance points.

Even the long back straight undulates, the huge, slightly bowed, 1200 meter length of tarmac rising and falling, leaving you wondering where you are along it.

The setting is beautiful, in the rolling low hills to the east of Austin, just beyond the airport, and the facilities are quite simply overwhelming: modern, well-equipped, brightly lit, attractively designed. Indeed, both the factory and Tech 3 Yamaha teams are delighted with the facility: after a battery fire at 1am, it was only the circuit’s outstanding sprinkler system and alert response by the fire service which prevented the fire spreading out of control, destroying maybe eight or twelve MotoGP machines, and causing upwards of $50 million of damage.

It’s back. The world is a better place now that young men are wasting fuel going round in circles at irresponsibly breakneck speeds on multi-million dollar motorcycles. (On a side note, someone pointed out today that a satellite 160kg Honda RC213V costs about half its weight in gold, at current prices, which suggests that a factory bike must be close to costing its own weight in gold).

The lights in the desert are once again spectacularly lit, and the sandy void which surrounds the Losail circuit again rings with the bellow of MotoGP bikes.

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.

This weekend’s Australian Grand Prix at Phillip Island is going to be a very Australian affair, more so than most other years. For one obvious reason: this is the last chance to see Casey Stoner race a Grand Prix motorcycle at the iconic venue before he hangs up his helmet and retires from MotoGP. Record crowds are expected, and local media coverage has expanded as everyone gathers to say goodbye to the latest in a long and honorable line of Australian Grand Prix champions who have left an indelible mark on motorcycle racing.

The weekend started off with Stoner’s name being added to those of Wayne Gardner and Mick Doohan, in a ceremony to rename Turn 3 Stoner Corner. Gardner’s name has been given to the front straight, Doohan’s to Turn 1, and Stoner’s name follows after the Southern Loop. It is a fitting tribute to the man who has started from pole four times in a row, won here five times in a row, and achieved some remarkable feats in MotoGP.

The Sepang round of MotoGP could see all three championships clinched this weekend, with Jorge Lorenzo, Marc Marquez and Sandro Cortese all closing in on their respective world championships. The job is easiest for Cortese, all the German has to do to become the inaugural Moto3 champion is finish one place behind Maverick Vinales and the title is his. After getting a little too excited at Motegi, Cortese will doubtless be heading to Sepang in a much calmer frame of mind.

Marquez also faces a relatively manageable task, but unlike Cortese, he does not have his fate entirely in his own hands. If Pol Espargaro wins at Sepang, then the earliest Marquez could be crowned champion would be at Phillip Island. If Espargaro does not win, the Marquez is in with a very good chance: should Espargaro finish the race in third or worse, then Marquez only has to finish directly behind him; if Espargaro finishes second, then Marquez has to win.

On current form, it would be hard to bet against Marquez, but Sepang was the circuit where the Spaniard was badly injured last year, suffering damage to his eyes which limited his vision and threatened to end his career. It will be interesting to see whether the memory has spooked Marquez, but judging by his performance this year, that seems faintly ridiculous.

Jorge Lorenzo faces the biggest challenge, with only a 28-point lead over Dani Pedrosa. Lorenzo will not only have to win at Sepang, but he will also need Pedrosa to finish no better than thirteenth. Given that the only time that either man has finished outside the top four has been due to mishap, the chances are the title chase will go down to Phillip Island, at the very earliest.

The press conference room at the Motegi circuit was a busy place on Thursday. The assembled press filed in twice during the afternoon, once to hear the head of Dorna talk about the long-term future of both motorcycle racing world championship series, and then again to hear five world champions talk about this weekend’s racing. There was much to digest.

What Carmelo Ezpeleta had to say about Dorna’s takeover of the World Superbike series has been covered elsewhere, though the irony of Ezpeleta hosting a press conference to talk about what was essentially an end run around HRC’s threats of a withdrawal at a facility owned and operated by Honda was not lost on everyone. The significance of the occasion was clear to all, and the groundwork has been laid for the future of both WSBK and MotoGP, though many fear the outcome.

An hour later, a much lighter mood prevailed when the riders filed in for the usual pre-event press conference. The long term was forgotten for a while, as everyone concentrated on two items: the return of Casey Stoner, and the impact of the Australian’s return on the championship. Will Stoner help Dani Pedrosa in his battle with Jorge Lorenzo for the 2012 MotoGP title? And is he fit enough and fast enough to be able to help if he wanted to?

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.
