Up until the start of MotoGP qualifying, it looked like Dani Pedrosa had the race at Brno just about wrapped up. The media center joke was that they might as well start writing his name on the trophy, so much faster was the Repsol Honda man. And then he crashed in qualifying, and started going an awful lot slower, in a tale that has echoes of Casey Stoner’s time at Ducati.

The crash was relatively simple – “maybe I was on the limit too much,” Pedrosa said, and Brno with its long corners, some flat and some downhill, means the riders are pushing the front for a lot of the time at the circuit – but the consequences were serious. Pedrosa returned to the pits, got on his second bike, and immediately had much worse chatter than before. Despite the setup being identical on both bikes. This is the kind of thing that Casey Stoner used to suffer at Ducati, two identical bikes that felt different, an issue that he never suffered at Honda. But the problem with hand-built prototypes is that apparently, even tiny deviations can cause a difference in feel, especially when pushed to their very limits by riders as sensitive as Pedrosa.

The issue highlights just how close Honda are to a solution. One apparently tiny difference between machines, and the difference is massive, from a bike that is almost impossible to go fast on to a bike that has some chatter, but is still rideable. Casey Stoner told reporters at the test at Catalunya that progress had been made by switching out a “two-dollar part”. There aren’t that many two-dollar parts on the bike, which means that somewhere a bushing or a spacer or an insert could be part of the solution. It also means that small variations in two-dollar parts – not known for requiring massive precision in manufacturing – could also be part of the problem.

Announcing ahead of Saturday’s qualifying session at Brno, Monster Yamaha Tech 3 has confirmed that it will retain Cal Crutchlow for the 2013 season, giving the French team an all-British rider line-up for next season, as Bradley Smith is set to move from Moto2 in the premier-class.

The re-signing of Crutchlow is an interesting move for the Brit, as he had been in the running for a factory seat within the Yamaha squad for most of the season, was also heavily linked to a ride in Ducati Corse for 2013, and there were even rumors of his return to World Superbike. With today’s news though, the speculation about Cal’s next season can be put to rest.

Friday would prove to be an eventful first day of practice at Brno. Thrills, spills, and plenty of flag waving, mostly of the red variety, as crashes played havoc with the day’s schedule. It started in the morning, during FP1 for MotoGP, when Valentino Rossi ran wide in the final corner, and his rear wheel kicked up a couple of sizable rocks. The rocks hit Dani Pedrosa, on the top of his foot and the front of his fairing, destroying the screen. How fast was he going when he was hit by the rocks, one intrepid reporter asked? “I don’t know my speed,” Pedrosa quipped, “but the rocks were going like they were shot out of a gun.”

And they weren’t small rocks either. Asked what size they were, Pedrosa held up both hands, touching thumbs and forefingers together to make a circle. “Like this,” he said. About the size of a grapefruit, then. Pedrosa said he had been worried that the impact had broken a bone in his foot, and the Spaniard was limping visibly as he got off his Repsol Honda, but the pain subsided as the session continued, reassuring him that there was nothing broken, just banged-up and bruised.

After the announcement that Casey Stoner would be flying back to Australia for surgery on his injured ankle, effectively ruling him out of contention for the 2012 MotoGP title, the Repsol Honda team organized a press conference to give Stoner the opportunity to explain his decision. The decision had not been an easy one, as Stoner had initially been intending to race at Brno, but a phone call from his doctors in Australia convinced him it would be too dangerous, as a crash could see him suffer permanent damage. It would be better to return to Australia, have surgery, and try to be fit enough to race again later in the year, with the goal being to return before Phillip Island to be as competitive as possible there.

After the news that Valentino Rossi was to make a return to Yamaha after two disastrous seasons at Ducati, Yamaha’s press officers were inundated with requests for interviews with Yamaha Racing Managing Director Lin Jarvis at Brno. To accommodate as many people as possible, Yamaha held a press conference to answer the questions that all of the assembled media wanted to put to them.

The subjects covered during the press conference were the motivation for signing Rossi after his two-year absence, whether Jorge Lorenzo had been consulted on the deal, and the pecking order inside the team. Jarvis also discussed the possibility of Jeremy Burgess and his crew joining Rossi at Yamaha, as well as commenting positively on Ben Spies’ performance over the past season.

Casey Stoner is to return to Australia to have surgery on the ankle he damaged in the qualifying crash at Indianapolis. After studying the MRI scans made in Indianapolis, Stoner’s Australia doctors have advised him he needs surgery to correct the damaged ligaments he tore at Indy.

The move means that Stoner will definitely miss this weekend’s Czech Grand Prix at Brno. How quickly the reigning World Champion will return is uncertain, though the surgery will require several weeks to recover. Already 39 points behind Jorge Lorenzo in the title race, missing Brno will put Stoner at an almost insurmountable disadvantage in the defense of his championship.

Nicky Hayden is to miss the Brno round of MotoGP. The American fractured a couple of bones in his right hand and suffered a concussion in a big crash at Indianapolis, highsiding his Ducati Desmosedici during qualifying on Saturday. Hayden’s injuries meant that he was unable to race at Indianapolis, and after consulting with doctors and the team, Hayden has been forced to pull out of Brno as well.

Not withstanding the drama of Liberty Racing and Sylvain Guintoli’s slightly absurd dustup and parting of ways, along with the news the BMW Motorrad would fold its factory team into the BMW Italia effort, it’s been business as usual at Brno for World Superbike this week. The same could not be said for Saturday’s Superpole event though, which suffered from fluids being dumped on the track, and then a bout of rain caused the qualifying to go to a wet format. With teams having to adapt to the changing format, the grid for Sunday is certainly an interesting one.

World Superbike in Brno this race-weekend, the home round for the Czech-based Effenbert-Liberty Ducati team. Once again in the spotlight after its dust-up following the Monza round, Effenbert Liberty rider Sylvain Guintoli took to Twitter ahead of WSBK’s stop in Brno, announcing in a string of messages that that Czech team had breached its contract with him by not providing a bike for the Czech round, and as far as the French rider was concerned, the contract had been nullified.

Giving its side of the situation several days later, Liberty Racing first cited an issue with Guintoli’s technical team, but later amended that statement by blaming Guintoli’s lackluster results as the reason for why the French rider had been sacked. This is of course in spite of the fact that Guintoli has been on the podium three times this season so far, including a race win in Holland. Guintoli is currently eighth overall in the Championship, and is the first Liberty Racing rider to have won a race in WSBK.

Naw…we’re just having some fun today, but not as much fun as Nicky Hayden’s pit crew during the Brno test. Staging this photo of the team supposedly starting up the Desmosedici’s new two-wheel drive system, the photo plays right into the rumors that Ducati is literally trying anything under the sun to make the GP11 work for Valentino Rossi and Nicky Hayden. With Filippo Preziosi essentially saying there are no sacred cows at the Italian racing effort, we honestly wouldn’t put it past Ducati Corse to give the two-wheel drive system a go…too bad its banned by MotoGP rules.
