Valentino Rossi’s amazing run of nine world titles was aided, in some part, by the level of those whom he had to fight for wins. With all credit given to Max Biaggi and Sete Gibernau, his two main rivals until the modern class of “aliens” arrived in MotoGP, neither of these two riders was on the same level as Casey Stoner, Dani Pedrosa, and Jorge Lorenzo.

My colleague David Emmett has commented several times that these three riders came up through their development years knowing that to win they would have to beat Rossi. They alone managed to elevate their skills to a level that could challenge him over the course of a season, where as Biaggi and Gibernau, as good as they were, could not manage the same growth as mature riders.

I’ve often considered how, to win as many titles as Rossi and Agostini have done, you need some help in the opponent department. Agostini benefitted from Mike Hailwood’s career choices and own bad luck when it came to finding a good fit on a competitive bike.

Rossi benefitted from arriving in MotoGP long before riders as good as Stoner, Lorenzo, and Pedrosa were around to fight him. If those three had been present in 2001 and riding at their full potential, it’s a safe bet Rossi would not have seven premier class titles in his pocket.

Tuesday afternoon at Valencia saw groups of people huddled together up and down the paddock discussing what to do. With the weather having made the first day of testing difficult, and much, much worse forecast for Wednesday – half an inch or more of rain was forecast to fall during the seven hours of the test on Wednesday – several teams contemplated the prospect of packing up and heading elsewhere in search of a dry track.

In the end only Yamaha decided to go, heading off to Aragon, one of their nominated test tracks. In their wake, a string of journalists followed, hoping to get more of an idea of just how fast Valentino Rossi still is after his misadventure with Ducati, by being able to compare his times with those of Jorge Lorenzo’s. It turned out to be a waste of time. The rain fell in Aragon, Valentino Rossi did a single lap – out, and then straight back into the pits – and Jorge Lorenzo posted nine laps in the wet before crashing, and walking away unhurt.

HRC has announced that it has signed Stefan Bradl as a “factory-supported” rider through the 2014 season. The move is surely a reward for Bradl, who easily claimed MotoGP’s “Rookie of the Year” distinction, and perhaps more importantly, showed extreme talent aboard the Honda RC213V.

Said to already have been using a factory-spec frame (Dani Pedrosa’s rejects) for the latter part of the season, it is not clear how much this announcement will change Bradl’s true support from HRC, but it certainly can’t hurt the young German’s chances. Bradl will stay within the LCR Honda team in 2013 & 2014.

If there is one subject that is getting mind-numbingly tedious to have to write about in motorcycle racing right now, it’s the weather. Almost every race this year has lost at least one session to difficult conditions, and we had hoped that the 2013 season might start off a little better. No such luck.

After a dry, clear night, the first rain showers arrived shortly before 10am, when the track was due to open for the test. By the time the track opened, enough rain had fallen to make it slick, greasy and extremely difficult to ride. That put an end to almost everyone’s carefully laid plans, leaving large groups of people wandering around and alternating between looking to the skies and carefully examining the track.

A few brave souls ventured out on to the track – including Valentino Rossi, at a few minutes after ten, the earliest he has ever taken to the track during testing since I’ve been following MotoGP, Rossi notoriously ill-disposed to mornings (as, I must admit, am I) – but for the most part, silence prevailed.

This was perhaps toughest on the TV commentators. Because of Rossi’s return to Yamaha, the first couple of hours of the test were streamed live on the MotoGP.com website, as well as broadcasted on both Italian and Spanish TV.

There was virtually nothing to show, though, except images of crowds milling in pit lane, riders wandering around chatting, some in leathers, some not, and endless repeats of slow-motion shots from the few bikes that had turned a lap in the morning, leaving commentators racking their brains for subjects to discuss, leading at one point to a surprisingly long discussion about fruit, and the riders who eat it.

Here’s one for the Rossi fans, the first photo of Valentino Rossi on-board the 1,000cc Yamaha YZR-M1 at the Valencia test (snagged by Monster Yamaha Tech 3 mechanic Steve Blackburn).

Apparently, the weather is being less than co-operative in Spain, with sprinkles of rain being reported, but that didn’t stop The Doctor from getting on-board “his” bike.

After the jump, there are 17 photos of Rossi’s maiden voyage back on the Yamaha YZR-M1 — all courtesy of photographer extraordinaire, Scott Jones.

The sense of expectation in the air at Valencia is wound so tight it hums. Tomorrow morning, some time after 10am, some of that expectation will start to dissipate as we get the first glimpses of answers that have preoccupied MotoGP fans for the past few months.

Two things we hope to see: a glimpse of the past and a glimpse of the future. After two long, hard years, the army of Valentino Rossi fans will be hoping to see something they haven’t since 2010, or maybe even 2009: a flowing, comfortable, aggressive Valentino Rossi at one with the machine underneath.

That was something he never showed while riding the Ducati, the figure in the Rossi replica helmet sitting on the Ducati always looking more like a club racer had sneaked into the back of the Ducati garage to take the bike out for a spin, terrifying himself in the process. Rossi looked stiff, awkward, uncomfortable, his back arched like a cat negotiating a dog-infested yard.

Tomorrow is like Christmas for motorcycle lovers, as Tuesday is the first official day of the EICMA show in Milan, and it is also the first day of the post-season MotoGP testing at Valencia. With more than a few riders swapping seats for next year, one of the most anticipated transitions is Andrea Dovizioso to the Ducati Corse factory team.

The third wheel at the Repsol Honda team in 2011, Dovi made the jump to the Monster Yamaha Tech 3 garage for 2012, with the hopes of auditioning for a seat on the factory Yamaha YZR-M1 next season. A certainly Valentino Rossi ruined that plan, so Dovi did the next best thing…he took Rossi’s seat at Ducati.

With the Ducati Desmosedici labelled as a career-ending machine, the GP11/GP12 nearly did The Doctor in, making the move by Dovizioso a brave one. Apparently trusting the words of Ducati’s new owner Audi, we will get our first glimpse of Dovi on the Ducati tomorrow, but for now we get our first photos of the pair’s preliminary introduction.

AMA Pro Racing Champion Josh Hayes will get a chance to swing a leg over some MotoGP machinery later this year, as the American rider will get to ride with the Monster Tech 3 Yamaha squad at the post-season test in Valencia. Taking place immediately after the final 2011 MotoGP round in Valencia, Hayes will ride Colin Edwards’ 800cc Yamaha YZR-M1, as the Texan Tornado will presumably be released from his Tech 3 duties so that he can begin testing his CRT bike at the first 2012 season test. The ride is joint-promotion by both Monster and Yamaha USA, and it also sees Josh Hayes’ better half, Melissa Paris, riding Bradley Smith’s Tech 3 Tech 3 Mistral 610 Moto2 race bike at the Spanish test.
