The Sepang round of MotoGP could see all three championships clinched this weekend, with Jorge Lorenzo, Marc Marquez and Sandro Cortese all closing in on their respective world championships. The job is easiest for Cortese, all the German has to do to become the inaugural Moto3 champion is finish one place behind Maverick Vinales and the title is his. After getting a little too excited at Motegi, Cortese will doubtless be heading to Sepang in a much calmer frame of mind.

Marquez also faces a relatively manageable task, but unlike Cortese, he does not have his fate entirely in his own hands. If Pol Espargaro wins at Sepang, then the earliest Marquez could be crowned champion would be at Phillip Island. If Espargaro does not win, the Marquez is in with a very good chance: should Espargaro finish the race in third or worse, then Marquez only has to finish directly behind him; if Espargaro finishes second, then Marquez has to win.

On current form, it would be hard to bet against Marquez, but Sepang was the circuit where the Spaniard was badly injured last year, suffering damage to his eyes which limited his vision and threatened to end his career. It will be interesting to see whether the memory has spooked Marquez, but judging by his performance this year, that seems faintly ridiculous.

Jorge Lorenzo faces the biggest challenge, with only a 28-point lead over Dani Pedrosa. Lorenzo will not only have to win at Sepang, but he will also need Pedrosa to finish no better than thirteenth. Given that the only time that either man has finished outside the top four has been due to mishap, the chances are the title chase will go down to Phillip Island, at the very earliest.

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.

Indianapolis is not given to great racing – a lack of use on the infield road course means that the track is usually fairly dirty once you get off line – and Sunday was no real exception. The MotoGP and Moto2 races were tactically brilliant and masterful displays of crushing the opposition, but neither was particularly entertaining to watch. Fortunately, nobody had told the Moto3 riders about the lack of great racing, and the youngsters got the day off to a fantastic start, with the race decided in the last sector of the track.

Great tracks produce great racing, even in the MotoGP class, where the combination of fuel limits, extremely advanced electronics, and stiff Bridgestone tires mean that the way to win races is by being absolutely inch-perfect on every lap.

And Mugello is a great track, there is no doubt of that, despite the fact that the usual Mugello atmosphere had been muted by a combination of a dismal Italian economy and sky-high ticket prices at the circuit, the only way for the circuit to recoup some of the sanctioning fee it must pay Dorna to run the race.

The hillsides were very sparsely populated, perhaps in part a result of the total Spanish domination of qualifying, putting three Spaniards on the front row in MotoGP, and another two on the Moto3 and Moto2 poles as well.

At the Sachsenring, after the introduction of KTM’s Moto3 GPR production racer, we spent five minutes with KTM’s Head of Motorsports Pit Beirer. We spoke to him about a number of subjects, including the evolution of the factory’s Moto3 chassis, the company’s cooperation with Kalex, and whether two-strokes would be better than four-strokes for racing.

Taking advantage of a quasi-home round for the MotoGP Championship at the German GP, Austrian company KTM debuted it latest “ready to race” machine, the 2013 KTM Moto3 250 GPR production race bike. A for-sale-version of its Moto3 Championship contender, the KTM Moto3 250 GPR borrows heavily from its GP-class predecessor, though comes in a slightly lower state of tune.

Featuring forged aluminum OZ wheels instead of magnesium ones, the production racer also comes sans Brembo brakes and WP suspension (items race teams would likely get from suppliers separately anyways). There is however one big technical difference, as KTM has reduced the bike’s maximum engine speed to 13,500 rpm, down from the 14,000 found on the factory bikes. This leaves the 2013 KTM Moto3 250 GPR production racer with just under 50hp on tap.

Bold and fearless or brash and ill-advised? There was a lot of that sort of thing at the Sachsenring on Sunday, in all three classes. (Spoiler Alert — Ed.) The most obvious example begging that question was what would have been Casey Stoner’s last-corner lunge past Dani Pedrosa, had it not gone horribly wrong as he lined the pass up the corner before. We’ll come to that later, but with a Moto3 race run in drying conditions and a Moto2 race where one of the favorites had to start from well down on the grid, there were plenty more to choose from.

It poured at the Sachsenring on Saturday afternoon. It absolutely hosed down, rivulets of water running across the track to make the conditions treacherous. Ideal conditions for Ducati, you would say, given their form so far this year in the wet, with Valentino Rossi on the podium in the downpour at Le Mans, and a 1-2 during the first session of free practice at a drenched Silverstone. But Nicky Hayden is 7th and Valentino Rossi 9th, a second or more off the pace of pole-sitter Casey Stoner. What went wrong?

There is a danger to thinking any championship is a foregone conclusion, especially this early in the season. Just as there is a danger to thinking that a race will pan out the way you thought it would after practice and qualifying. At Assen, everyone was afraid of three things: the weather, Jorge Lorenzo, and Pol Espargaro. All three turned out differently than expected.

Best of all was the weather. After treacherous conditions on Friday, with rain falling, stopping, wetting the track just enough for Casey Stoner to bang himself up badly in the morning, though that did not stop him from blasting to pole, Saturday dawned bright and only got better: the big skies of flat-as-a-board Drenthe were mainly blue, with the occasional sighting of fluffy white clouds to provide a little cover and prevent egregious sunburn. But best of all, it stayed dry: no complications, just sunny, dry and calm weather.

Neither Lorenzo nor Esparagaro would prove too pose much of a threat either, Lorenzo through no fault of his own, but Espargaro would need no outside help in taking himself out of the equation. The crashes of Lorenzo and Espargaro – Lorenzo taken out by a boneheaded move from Alvaro Bautista, for which the Gresini Honda man will have to start from the back of the grid at the Sachsenring, Espargaro crashing on a bump at the Ruskenhoek – put an end to the domination of the two men in the MotoGP and Moto2 classes.

Espargaro had blasted every sessions of free practice, and only a blistering lap from Marc Marquez had denied the HP Pons rider pole. Lorenzo’s domination had been more subtle, his race pace clearly several tenths better than anyone else, though others on soft tires occasionally bettered the Spaniard during practice and qualifying.
