For the next few days, Asphalt & Rubber will be coming to you from Austin, Texas, so needless to say we’ve got the Circuit of the Americas on our brain.

Host to MotoGP’s second round this season, COTA is the first of three American rounds, which makes the United States of America the second most popular country for the premier racing series.

A new venue for all the riders, the factory HRC and Yamaha Racing GP racers got a chance to lap COTA for the first time last week, and gave generally positive feedback about the purpose-built course.

With the Repsol Honda media machine in full-swing now though, Honda rider and rookie sensation Marc Marquez gives a more detailed opinion about the Circuit of the Americas, and the pre-season testing thus far.

Check out the video after the jump and feel the media grooming that is going on here.

So the three days of testing at Austin are over, and what did we learn? That Marc Marquez is something special? We knew that, though we didn’t perhaps realize just how special. That Yamaha really needs to find more acceleration? This, too, was known, but becoming clearer every time the M1 goes up against the Honda RC213V on track. That Valentino Rossi’s return does not equate to an automatic 8th MotoGP title? We suspected as much.

The first thing that became obvious is that the Austin circuit itself is pretty decent. Valentino Rossi described it as “a typical Tilke track, with corners that remind you of Shanghai and Turkey.” Unsurprising, given that Herman Tilke, who also designed Shanghai, Istanbul, and many other race tracks around the world, was responsible for designing the track.

The input from Kevin Schwantz was helpful, though, making the track more like Istanbul than Shanghai. The circuit has a couple of highly technical sections, where you go in blind and need to have memorized which way the track goes. It is wide, giving opportunities for overtaking and braking, and has a couple of the fast, fast sweepers which motorcycle racers love.

It also has a couple of tight corners, leaving the bike in a low gear with a lot of acceleration to do. This, it became apparent, favors the Hondas, the RC213V strongest off the bottom, and capable of pulling a gap. Acceleration issues will be a problem for Yamaha this year, unless Masahiko Nakajima and his fellow engineers can find some extra grunt out of the corners.

The situation was similar in 2012, but Yamaha was helped by the problems the Hondas had with chatter. So far, the Repsol Honda men have remained silent on the issue, meaning the worst of it is over. Yamaha have their work cut out, and Jorge Lorenzo’s second title defense could be a little too reminiscent of his previous one in 2011.

With the second test at Sepang International Circuit completed, Repsol has released a short video of Dani Pedrosa and Marc Marquez that is packed with on-board footage. Jarring at times, it is clear to see which sections of the Malaysian circuit are rough and bumpy, though we think the most interesting aspect is the blacked-out dash on the video.

Not wanting to give away any secrets, like the Honda RC213V’s 90° V4 engine configuration for example, HRC has made sure that no one can guess the revolution figures of its engines. With Dani Pedrosa looking extremely potent for the 2013 MotoGP Championship, we can understand why. Check the video out after the jump.

Dani Pedrosa was once again fastest on the final day of testing at Sepang, topping the timesheets for the fifth time in six total days of testing at Sepang. Though the Repsol Honda man looks to be the pre-season favorite so far, he does not leave the test as fastest overall, however. That honor goes to Jorge Lorenzo, who put in a scorching lap on Wednesday to set the fastest time over all three days of the test.

The riders got off to a late start on Thursday, rain meaning that the bulk of the riders kept to their garages until the track started to dry out at the end of the morning. A few men put in laps in the wet, but once the track dried out, enough riders started putting in laps to clean the worst of the dirt left by the rain from the track, though track conditions were never as good as on the first couple of days.

Pedrosa soon took charge of proceedings, later knocking another half a second off his time late in the afternoon. Rookie Repsol teammate Marc Marquez impressed yet again, taking 2nd on the timesheets with his very last lap, after the final 30 minutes of the session turned into a qualifying session.

Marquez continued to concentrate on learning the ropes on a MotoGP machine, and the longer runs he put in were a little further off the pace of Pedrosa, and still not as consistent as they will need to be, but he proved with his flying lap that he will be starting from the front of the grid by the time the season starts.

Jorge Lorenzo ended the final day of the test with the 3rd fastest time, but leaves Sepang as fastest overall. Lorenzo’s best time was over four tenths slower than Pedrosa’s on Thursday, but the Spaniard spent the latter part of the day working on race set up, ending the test with a mightily impressive race simulation of 20 laps, 16 of which where in the 2:01s, most of them fast 2:01s.

Lorenzo’s race simulation follows the pattern from his championship-winning season in 2012, making a very long race simulation to test the bike and himself in punishing conditions. Less characteristic was a mistake the Spaniard made, putting in one lap of 2:05 towards the end, an anomaly among the scorching laps that surround it.

After announcing a “dream team” line-up for its 2013 season, Honda TT Legends has had to revise its rider-entry list, after coming to a mutual decision with Australian racer Cameron Donald, who will not not race with the Honda TT Legends World Endurance Championship squad this year.

Citing personal reasons, namely the desire to spend more time with his family, Donald’s absence from the Honda TT Legends team means that the HRC-backed squad will field a three-rider effort in this year’s four endurance rounds, leaving John McGuinness, Michael Rutter, and Simon Andrews to campaign on the Honda CBR1000RR endurance race bike.

Jorge Lorenzo has topped the second day of testing at Sepang during the MotoGP class’ second visit to the circuit, the factory Yamaha man finding the three tenths of a second he was seeking on day 1 of the test. Lorenzo was quick right out of the gate, setting a blistering mid-2:00 lap on his first exit, a time nobody would better except himself before the afternoon break.

Even more impressive than his time is his consistency, however: Lorenzo is seemingly able to crank out mid-2:00 laps at will. The Spaniard’s performance so far has been eerily similar to the test last year, where he laid the foundation for his 2012 title by grinding out lap after lap at race pace.

With Lorenzo on top of the timesheets, Dani Pedrosa was forced to settle for second, over a third of a second behind his main rival for the title. Pedrosa had spent most of the day working on suspension settings for Honda RC213V, but had been hampered by a problem with one of his bikes. Tomorrow, he told reporters, his team would try to put the best of what they’d found at the test together.

An impressive Cal Crutchlow set the 3rd fastest time of the day, the Monster Tech 3 Yamaha man six tenths off the pace of Lorenzo on the factory bike. The lap by Crutchlow is close to his best time around the Malaysian circuit, and given the disparity between his satellite-spec M1 and the factory bike of Lorenzo, all the more admirable.

Dani Pedrosa has taken up at the second Sepang MotoGP test where he left off after the first. The Repsol Honda man led for most of the day, having set a fast time fairly early in the morning. His rival at the Factory Yamaha squad did much the same, Jorge Lorenzo taking 2nd a couple of tenths behind Pedrosa.

Marc Marquez continues to impress, the Spanish prodigy ending the day with the 3rd fastest time, just over a third of a second off his Repsol Honda teammate, and a little over a tenth behind reigning world champion Jorge Lorenzo.

Also impressive was Stefan Bradl, the LCR Honda man achieving his stated aim for the test of matching the pace of Valentino Rossi. The strong times by Marquez and Bradl demoted the Factory Yamaha returnee to 5th, though the difference was minimal, just a few hundredths separating the threesome.

After an absence of some three weeks or so, the MotoGP teams once again return to action at Sepang for the second official test of the pre-season. The intervening period has seen a flurry of activity in the factories in Japan and Italy, and at CRT team headquarters around Europe.

The data accrued on the first visit to the Malaysian circuit has been analyzed, assessed, and more modifications made and ideas worked out for the second Sepang test. So what can we expect to see in Malaysia for the next three days? And what are the key details to keep an eye on?

Just over 18 months ago, I wrote a long analysis of what I believed at the time was the main problem with Ducati’s Desmosedici MotoGP machine. In that analysis, I attributed most of the problems with the Desmosedici to the chosen angle of the V, the angle between the front and rear cylinder banks.

By sticking with the 90° V, I argued, Ducati were creating problems with packaging and mass centralization, which made it almost impossible to get the balance of the Desmosedici right. The engine was taking up too much space, and limiting their ability to adjust the weight balance by moving the engine around.

Though there was a certain logic to my analysis, it appears that the engine angle was not the problem. Yesterday, in their biweekly print edition, the Spanish magazine Solo Moto published an article by Neil Spalding, who had finally obtained photographic evidence that the Honda RC213V uses a 90° V, the same engine angle employed by the Ducati Desmosedici. Given the clear success of the Honda RC213V, there can no longer be any doubt that using a 90° V is no impediment to building a competitive MotoGP machine.

The photographic proof comes as confirmation of rumors which had been doing the rounds in the MotoGP paddock throughout the second half of the 2012 season. Several people suggested that the Honda may use a 90° angle, including Ducati team manager Vitto Guareschi, speaking to GPOne.com back in November.

I had personally been lucky enough to catch a glimpse of a naked RC213V engine at one rain-soaked race track in September, but while the glimpse through the window may have been good enough to form the impression of an engine that looked like it may have been a 90°V, it was a very long way from being anything resembling conclusive, and nowhere near enough to base a news story on.

Spalding’s persistence has paid off, however. The British photographer and journalist is a common sight wandering among the garages, either first thing in the morning, as the bikes are being warmed up, or late at night, while the mechanics prepare the machines for the following day.

At some point, the Honda mechanics and engineers – protective to the point of prudishness of displaying any part of their machine to the outside world – would let their guard slip. When they did, Spalding pounced.

So why did Honda elect to use an engine layout which is blamed for causing Ducati so much trouble? And how does Honda make the layout work where Ducati have continued to fail? The first question is relatively simple to answer; the second is a good deal more tricky.

The internets are a buzz today with photos from the MotoGP test a Sepang, which seem to suggest that the 2013 Honda RC213V prototype race bike has a 90° V4 engine configuration. The news should certainly come as a surprise for many Ducatisti MotoGP fans, as Ducati Corse’s front-end woes have often been attributed by couch racers to the Italian company’s 90° V4 engine configuration. Seeing how dominant Honda has been at the pre-season testing in Malaysia though, one cannot help but admit that the cylinder configuration is not necessarily to blame for Ducati’s troubles.

Talking to Spanish magazine SoloMoto, HRC boss Shuhei Nakamoto explains that the 90° V4 engine has benefits over the company’s previous 75° engine configuration, namely that the 90° engine doesn’t require a balancing countershaft. Nakamoto-san further explains that because of the balancing shaft’s absence, Honda’s 90° V4 runs with more power, and less vibration that its 75° predecessor, making the engine a formidable enhancement to the RC213V platform.
