The chance to substitute in the Repsol Honda team for the injured Casey Stoner was a great opportunity for Jonathan Rea to get a feel for a MotoGP bike and demonstrate his talent and potential, objectives in which he succeeded admirably. But it was also a chance for MotoGP journalists to grill the Ulsterman on the differences between various aspects of MotoGP and World Superbikes, Rea having shown he was both fast enough to feel the difference, smart enough to understand the difference, and articulate enough to explain it to reporters.

At Aragon, the subject turned to electronics, and the difference between the systems used in the two series. The topic was broached as Rea was explaining what had happened to him during the race. He had got caught up cycling through the various electronics strategies the Honda RC213V is equipped with, looking for one that would help him as the tire wore throughout the race. A lack of dry track time getting to understand how the electronics affected the bike as the tires begin to wear left him confused and struggling to find a setting that would work, Rea told reporters.

After two days of miserable weather at Aragon, race day dawned dry, sunny, though still a little cool. Paddock regulars who had spent the last two days scurrying from pits to hospitality, seeking shelter from the rain, poured out into the paddock to catch the warmth of the sun, which they had just about given up on previously.

The blue skies brought out some great racing, at least in Moto3 and Moto2, as well as some fantastic displays of riding in MotoGP, though the excitement in the premier class was to be found in the battle for the final spot on the podium rather than in the fight for victory. But there were also a few signs of improvement in the near future.

With the MotoGP paddock assembled at the Motorland Aragon circuit, the press got their first chance to gauge rider reaction to the proposal of a spec ECU which Dorna is looking to introduce into MotoGP, most probably from 2014. The reaction was guardedly positive among the MotoGP regulars, though all five riders questioned in the pre-event press conference raised concerns over safety. Only Jonathan Rea, standing in for Casey Stoner in the Repsol Honda team for probably the last time, dissented, believing that MotoGP should be a pure prototype series.

“If everyone has the same electronics, this will be positive for everyone, more positive for the ones who do not have the best electronics,” Jorge Lorenzo told the press conference. He was the first to voice safety concerns. “I think we have to try it and to see if we still have the same security on the bike. Because now we avoid a lot of crashes, especially highsides, and maybe with the standard electronics the bike is a bit more dangerous. Because now, the bikes are more powerful, we have more than 250 horsepower, so we have to be careful of these things.”

Yamaha Racing has debuted its “Race-Blu” livery at Misano today. The work of Aldo Drudi (of Valentino Rossi helmet fame), the blue and matte grey paint scheme is the same special color schemes that will be available on the Yamaha YZF-R1, YZF-R6, and YZF-R125 bikes for 2013, seemingly everywhere except the United States.

Yamaha says the livery is a throw-back to its historic racing blue colors of the 1980′s. Factory riders Jorge Lorenzo and Ben Spies will also wear special Race-Blu leathers for the races at Misano and Aragon. Will the special livery prove to be as lucky as the Red/White 50th Anniversary livery? Only time will tell.

If you’ve already watched the Aragon GP, you may already have noticed the fact that the Repsol Honda team was using special livery for MotoGP’s penultimate European round. Decked out in special starred race livery created by Spanish designer Davidelfin, Repsol’s riders sure were the stars of the weekend, helping the Spanish company celebrate its 100th Grand Prix victory.

Achieving their first premier-class win at the 1995 Australian GP with Mick Doohan, Honda and Repsol’s partnership in GP racing has been a fruitful one to say the least. Looking for at least one Championship win during the 800cc era of MotoGP, Repsol Honda seems well on its path after this weekend at Motorland Aragon. Check out Davidelfin’s special Repsol Honda livery after the jump.

Though threatening with strong winds and the possibility of rain, the weather held out for MotoGP riders at the Aragon GP. As the Spanish track played host to the premier class of motorcycle racing, the Aragon GP proved to be a Honda affair during qualifying, as Casey Stoner took yet another pole position, while teammate Dani Pedrosa followed closely behind as second on the grid. With Jorge Lorenzo struggling at Motorland Aragon, Ben Spies carried the Yamaha banner to the front row, qualifying third on Saturday.

The first to break the six engine rule allotment (we should add, without a special dispensation) Valentino Rossi took his seventh motor of the season, and thus was relegated to starting from the pit lane, 10 seconds after the start of the Aragon GP. Perhaps the friendliest track to take such a manuvear, Ducati Corse is clearly not only thinking for the long-term of this season, but also for the 2012 season as well. How would starting from the rear affect the nine-time World Champion, and would Jorge Lorenzo continue his pursuit of Casey Stoner at Aragon? Find out after the jump.

With power issues plaguing Friday’s Free Practice sessions, MotoGP took to the track Saturday in full-effort as riders and teams scrambled to make up for lost time. One of five races remaining in the season, the Aragon GP continues Jorge Lorenzo’s do or die point of the season, as the reigning-World Champion is on a campaign to claw back Casey Stoner’s 35 point lead in the MotoGP Championship standings. With the Yamaha’s struggling at Motorland Aragon, the Spaniard certainly has a tough a weekend ahead of him, especially since both Casey Stoner and Dani Pedrosa looked to be well on top of their game in the two practice sessions.

News has been percolating for Ducati as well, as Valentino Rossi will finally ride on the much rumored aluminum chassis this weekend. While Rossi and the Corse crew struggle to adjust to yet another major modification to the Ducati Desmosedici, Randy de Puniet proved to be the fastest Italian bike man at Aragon leading up to qualifying. Also showing strong improvement in this homestretch of the season, Alvaro Bautista has been on a tear lately, and will be man to watch come Sunday’s race.

Valentino Rossi finally put an end to the speculation today at the MotoGP pre-race press conference, and announced that Ducati Corse will use an aluminum chassis during the Aragon GP this weekend. First tested last week on the Ducati Desmosedici GP12, the FTR-built aluminum frame has improved the front end feeling for the Desmosedici, an issue that has plagued the Ducati all this season. Rossi will first use the new aluminum parts during Free Practice tomorrow, though the team hasn’t confirmed their use in the race just yet.

“We tested last week after the race, and it was not so bad,” said Rossi when talking about Ducati Corse’s post-Mugello test. “We tried something different on the bike to improve the front feeling and turning, and the lap times were not so bad. I was a bit faster than the last time, and basically the feeling was quite good, so we’re moving forward.”

When pressed about what changes Ducati made, and whether or not Rossi test the rumored aluminum frame, the nine-time World Champion was quick to correct. ”It is not a frame,” explained Rossi. “The philosophy of the Ducati is the same, but the front part of the bike is a bit different, and is in aluminum, and not in carbon like before. But about the material, it is a question of time. We have to work to try and understand how the bike and with aluminum you need a lot less time compared to the carbon. The bike improved a bit, but this is just the first step. We need to keep working to come back and fight for the front.”

Dorna keeps pretty tight controls on what information gets out about its business; but when dealing with public entities, some of those figures are bound to come forth. Such is the case with Motorland Aragon, the Spanish track that recently locked in MotoGP through the 2016 season. The cost of hosting MotoGP for the next six years? €41 million. That figure breaks down into €6 million for the 2011 round, €7 million for the 2012 season and subsequent years as well.

Be careful the next time you heckle a MotoGP rider on Twitter, because they might just respond. Such was the case when a fan chastised Lorenzo, who was upset about his performance during the Aragon GP. Catching the attention of Lorenzo, the fan promptly found himself on the wrong end of a retweet from the Spanish rider. Zinger! Thanks for the tip David!
