Defending titles is not easy. In the last twenty years, only Mick Doohan and Valentino Rossi have managed to win successive championships, despite both Jorge Lorenzo and Casey Stoner winning twice. Why is it so hard? A lot of reasons. Nothing motivates a rider, a team or a factory like losing.

Winning a championship requires a lot of hard work and talent, but also a smattering of luck, and at some point, luck runs out. Winning a title means always looking forward, eyes on the prize, while defending a title means looking back, at everyone out to get you. All these things combine to make winning the second title in a row much, much harder than winning the first one.

The second day of the special CRT test at Sepang, laid on to allow the teams using the brand new Magneti Marelli spec-ECU, was as beset by problems as the first day. If technical problems and a lack of parts had been the bane of day 1, it was the weather which dogged the teams, though technical problems persisted.

Heavy rain in the morning meant that only Danilo Petrucci went to put in a few laps before running into an electrical issue with a coil left the engine running on two cylinders. The rain stopped in the afternoon, but the track remained wet, leaving the riders present to do only a few laps.

Petrucci ended the day fastest – though his best time of 2’23.546 is fairly meaningless at a track where the race lap record is 2’02, and the pole record 2’00 – but frustrated at having not been able to get much work done. The electrical problems left him stranded in the pits in the morning, while teammate Lukas Pesek took the only Magneti Marelli ECU the team currently has at their disposal in the afternoon.

Another GP race weekend, and another weekend where the weather looms over the MotoGP paddock. Wasting Friday, and getting a reprieve on Saturday, the rain of Valencia was back for Sunday’s race, leaving a drying, but wet, course for the MotoGP riders to contend with on 200+ hp machines.

Casey Stoner’s last race, Dani Pedrosa’s last chance to have the most race wins, and Jorge Lorenzo’s final chapter to a flawless season, the script for the front-row starters was intriguing to say the least.

It all went out the window though, as we can confidently say that the following information contains no spoilers for those who have yet to see the race, since no human could possibly guess the outcome of the Valencian GP: a CRT bike lead the race for multiple laps, a Yamaha is on the podium, a world champion was lapped, and a satellite team finished both its bikes in the Top 5. Words can barely describe the race, but we will try after the jump.

With a mixture of wet and dry conditions occurring during the race-week for MotoGP at Sachsenring, qualifying for the German GP was a strictly rainy affair. The great equalizer, the rain proved to throw a wrench in the usual procession of riders, as MotoGP gets ready for its second round of three back-to-back race-weekends.

Adding drama to the event was the deadlock in the 2012 MotoGP Championship between Jorge Lorenzo and Casey Stoner, as Alvaro Bautista took out the Spaniard in the first corner of the Dutch TT. For his crimes against Spanish supremacy, Bautista will start from the back of the grid, regardless of his qualifying effort today.

The 2012 PokerStars Senior TT is making history books, despite the fact the race was postponed from Friday to Saturday, and ultimately cancelled late in the afternoon on its rescheduled race day. The first time the Senior TT has been called for track conditions, the only other time the blue ribbon race has failed to run has been during the TT’s racing suspension for WWI and WWII.

Leaving fans to wait along the Mountain Course for several hours, the race was finally scrapped after a contingency of TT riders viewed the full course via automobile. Finding damp patches along sections like the Mountain Mile, John McGuinness et al deemed the race too risky for the 200+ bhp superbikes, though they thought that the tamer inaugural Lightweight class (650cc twins) would be alright to make the run.

All last season, and for the first three races of 2012, when I’ve walked past the Ducati garage and looked in at Rossi’s side, watching for an interesting moment to photograph, I’ve seen pretty much the same thing: Immensely talented people looking immensely frustrated. I stand there for a moment and think, I’ve already taken this photo, many times. When are things going to change in there?

Things changed this weekend at Le Mans. But after three races in a row, I’d elected to be home for some family events instead of away at the French GP. From the perspective of getting different images of the Ducati box, this was bad timing. But in other ways, and not just family-related, it was good timing indeed, because I watched the race with friends at the San Francisco Dainese Store, which was, as one might expect, full of Rossi fans. And being there was a bit like going back in time.

For some, the KTM 125 Duke is just not quite enough machine to get their two-wheeled juices flowing, and thus the KTM 200 Duke & soon-to-be-expected KTM 350 Duke were born. With the Austrian motorcycle maker KTM partnering with India’s second-largest motorcycle brand Bajaj to make the baby Duke, it should come as no surprise then that many of these models are ending up outside of Europe, and in Asian markets…namely India itself.

While us Westerners might think of the KTM 200 Duke as a fairly practical machine, buyers in India are a bit more skeptical, since their day-to-day travel can be a bit more varied than ours. You see, India right now is preparing for its summer monsoon season, and flooding in certain regions is more of a certainty than a special phenomenon. So while an underslung exhaust might look stylish to us Americans, to an Indian motorcyclist it could look to be more of a liability.

Hoping to purge that thought from Indian riders’ minds, KTM has put together this video outlining its wet-weather survivability testing. If you ever wanted to know whether you can park the KTM 200 Duke in wheel-high water for 30 minutes or more sans snorkel, check out the video after the jump.

With World Superbike’s stop at Monza being massively disrupted by the combination of the track’s demanding layout and Pirelli’s melting rain tires, the Italian tire company has taken the brunt of criticism from fans, teams, and riders for its handling of the two races at the historic circuit. With the long straights and high speeds of Monza proving to be a challenge in even normal conditions, the issue of tires became increasingly important as it was discovered that the compound used in Pirelli’s rain tires could not handle the center-line heat caused by the Italian track, even in full-wet conditions.

WSBK fans watched as riders blew through rain tires in just a matter of two or three laps during the wet Superpole qualifying session on Saturday, and when the rain showed up again on Sunday, the riders had said they had enough of the nonsense. Though not encountering fully-wet conditions, Pirelli’s intermediate tire was ruled out of the equation, as it uses the same compound as the rain tire, albeit with fewer groves. So, Pirelli’s solution to the problem was to take racing slicks of different compound, presumably one that could handle the heat of the track, and cut them to into makeshift intermediate tires. Expecting riders to go two races on a pair, the WSBK paddock was less-than-enthusiastic with this remedy.

With the riders essentially causing a mutiny on the starting grid, Race 1 at Monza was cancelled, while Race 2 was delayed for dryer conditions. Once the rain returned halfway through the race though, riders again raised their arms to signal the stoppage of the competition. Since they completed half of the race, only half points were awarded, but that left for some interesting comments in the paddock. Responding to the criticism of how it handled the Monza weekend, Pirelli has released a press statement that shifts the blame back to the World Superbike teams. Read the company’s statement in its entirety after the jump.

After seeing Race 1 cancelled for safety concerns, i.e. not having a rain tire that could run in the wet conditions at Monza, World Superbike tried again to put on a show for the Italian fans. Giving riders two warm-up laps to sight the fabled Italian circuit, the race distance was also reduced by a lap to 17 laps total.

With the riders coming in from their two sighting laps, the hands from a majority of the racers went up on the grid, signaling that they did not want to start the race. Race Direction obliged, and delayed the start because of the conditions. Regrouping and going out on another warm-up lap, Monza continued to be problematic and claimed two victims, as BMW Italia rider Michel Fabrizio and pole-setter Sylvain Guintoli both suffered from malfunctions on the lap, and had to scratch their starts.
