With rain the night before, MotoGP’s first day of testing in Sepang got off to a late start, with riders not taking to the Malaysian track until well into the day. Noticeably absent from the day’s test was reigning-World Champion Casey Stoner, as the Australian’s back seized during stretching before the first session. Casey is expected to ride Wednesday (Tuesday evening US time), though former-teammate Andrea Dovizioso is a question mark, as the Monster Yamaha Tech3 rider was too sick for a media debrief last night.

For the Ducati camp, initial results are looking positive, as the factory Ducati Desmosedici GP12 had its first shakedown from riders Valentino Rossi and Nicky Hayden. Still recovering from his broken shoulder, Hayden only put in 25 laps on the new GP12 “Phoenix” before calling it a day and letting test rider Franco Bataini finish the day’s testing for him. Rossi on the other hand had a full-day with the Ducati Corse’s GP12, and was already impressed with the bike and the progress Ducati had made with it.

“I’m happy because first impressions are important, and already in the first few laps, I could tell that I like the bike,” said the nine-time World Champion. “Ducati did a good job in a just a short time. The bike is beautiful, but more importantly, it’s nice to ride. The riding position has improved a lot, and it’s better on braking and corner entry. I can brake like I want to and take the lines that I like, and I feel comfortable in general.”

While Ducati Corse is busy playing hide-the-Desmosedici at Sepang, HRC is all business in Malaysia this week, and has debuted its 2012 Honda RC213V MotoGP-contender. Honda isn’t saying too much about the RC213V, simply stating that the race bike is all new, but is also a continuation of the company’s design with the 800cc Honda RC212V. Testing the Honda RC213V over the course of last season, reigning-World Champion Casey rode the new 1,000cc machine three times in 2011, while teammate Dani Pedrosa swung a leg over the RC213V twice (missing one test because of injury).

With testing at Sepang to start Tuesday local time (later tonight for us Americans), we won’t have to wait long to see how the Honda stacks up against the factory Ducati Desmosedici GP12 and the yet-to-be-seen 2012 Yamaha YZR-M1. With Dani Pedrosa besting Stoner at the Valencia test, there should be a good battle within the Repsol Honda team for the World Champsionship title defense. If Pedrosa can stay healthy, he could be a real threat to stoner. Though, the Australian won 13 of last season’s 17 races, making him the favorite going into the 2012 season. Photos after the jump.

With rain coming down during the 125GP session, MotoGP narrowly avoided its own water-soaked qualifying. With wet sessions on Friday, the order of things was disrupted as the Ducatis clearly could overcome their problems in the damp conditions. As the track dried though, the Honda dominance returned, making the Spanish skies a huge factor for Sunday’s Valencian GP. Depending on who you talk to in the paddock, it’s either a guarantee for rain tomorrow, or it will be assuredly sunny, meaning no one has a clue what the weather will really be like.

While Stoner and Pedrosa have had their accustomed positions on the time sheets, Valencia has seen moments of brilliance from Hayden, Rossi, de Puniet, and Bautista, as all four riders have had an extra pep in their step during the inclement weather. The Spanish venue seems especially to favor the Spaniard Bautista, as the Suzuki rider has been a cut faster than previously in the season, no doubt encouraged by a home crowd and the desire to help Rizla Suzuki secure a future in MotoGP.

The other notable standout this weekend has been American Josh Hayes, who has been aided by the rain and adapted readily to the Monster Tech3 Yamaha YZR-M1 typically ridden by Colin Edwards. Not having to learn the carbon brake discs of MotoGP, and with the Bridgestone tires blunted by the water, Hayes has come up to speed rather quickly on the M1, finishing FP1 with a respectable P10. How that learning curve would change in the dry though remains a pressing question mark on the AMA Superbike Champion’s mind, though that seems to be the case for many riders this weekend.

With just two rounds left in the season, MotoGP comes to Sepang this weekend for the Malaysian GP. Dominating the Free Practice sessions, Honda clearly has the Asian track’s number, while the rest of the field shows signs of a long season. Hector Barbera leads the walking-wounded, as the Spanish rider has fought through the race weekend, nursing his stapled shoulder through each session. Barely able to complete a few laps at a time, there are serious doubts about the Mapfire Ducati rider’s ability to ride the full-race distance, though no one is questioning his determination.

While Barbera will likely give the race his best effort, Rizla Suzuki wild card John Hopkins has already thrown in the towel, as the extreme physical demands have aggrivated Hopper’s hand injury beyond his tolerance. In the Yamaha tent, Jorge Lorenzo is of course absent, after his traumatic finger injury in Phillip Island. Replaced by Yamaha test rider Katsuyuki Nakasuga, Lorenzo’s absence and an ailing Ben Spies have made Sepang another forgettable race weekend for Yamaha Racing. Still sore from his high-speed crash in Australia, the American Spies has noticeably not been himself, with his chest and ribs still bothering him considerably. The one glimmer of hope for Yamaha in Malaysia has been Colin Edwards, who has been one of the few riders able to mix things up with the four factory Hondas.

Though grip issues from the intense heat have plagued the field throughout the weekend, Sepang has otherwise provided MotoGP with perfect weather for the Malaysian GP. The heat has been a mixed bag for Ducati Corse, as Valentino Rossi and his crew have noticeably been off the pace, and not able to capitalize on the team’s off-season testing at Sepang. Meanwhile, Nicky Hayden has been shining on the Ducati Desmosedici GP11.1, as the American and former-World Champion has been the Italian bike to beat, and have been showing strong second row potential. How would everyone sort out in qualifying though? You can find out after the jump.

A less well-known MotoGP factoid is that Honda owns the Twin Ring Motegi circuit, though to the casual observer HRC clearly had a dominate presence at Motegi this weekend, with eight bikes on the grid throughout the race weekend. As the Yamahas struggled throughout the week, and with Ducati still hunting for a setup that will allow them to compete near the front, Honda continued to make a point of national unity at the Japanese GP going into Sunday’s race, a fact that has been further underlined by the company’s continued dominance in the 2011 season.

After a dominant finish in Aragon, Casey Stoner had all but won the 2011 MotoGP Championship, though few expected the Australian to take things easy in Japan this weekend. No longer nipping on Stoner’s Championship heals, Lorenzo came to Japan with a tall order to defend his #1 plate, though mathematically the reigning-World Champion hasn’t been ruled out of the Championship. Expected to push hard for the rest of the season, Lorenzo’s fate this season rested on the hopes for a mistake from the seemingly unstoppable Stoner.
