That was a chaotic weekend. Two-and-a-half days lost to rain, then a bizarre series of hold-ups and incidents on the start of the MotoGP grid that ended up eventually going a long way to deciding the championship. Fortunately for the series, the MotoGP race was preceded by two scintillating support races, and then the MotoGP race itself saw two very popular podiums.

To start with the biggest issue, the start and then the restart of the MotoGP race. There was a lot of confusion and head-scratching over what was going on – the riders had never seen the flashing amber lights on the starting panels, for one – but when the dust settled, it looked like everything had been run almost by the numbers, despite the protests from Dani Pedrosa’s camp.

The sequence of events seems to have been this: After the first warm up lap, the riders lined up on the grid ready to go, but after the starting lights had been shown, Karel Abraham had a clutch problem and put his hand up to indicate that his bike was not working. Once that had happened, Race Direction had no option but to call off the start. They ran this by the book: flashing yellow lights were displayed next to the red lights, and yellow flags were waved. There was as short of an interval as possible, before the bikes set off for the second warm-up lap, and race distance was reduced by a single lap.

Even before the lights could go out to start the San Marino GP, the pre-race drama for MotoGP fans was intense. Stalling on the starting grid after the riders’ sighting lap, Karel Abraham raised his arm to signal the dangerous race conditions. Virtually a moment away from the start of the race, the yellow flags of the marshals flew, and the start was aborted — though, the confusion didn’t stop some riders from rocketing off the line. Thankfully however, the situation was without incident.

With a number of bikes needing to be restarted because of the failed start, teams and mechanics again filled the grid, and the start of MotoGP’s visit to Misano was delayed. No one was more affected by the restart than pole-sitter Dani Pedrosa, whose Honda RC213V had its front wheel locked-up when the team attempted to take off the tire warmers for the race’s restart. With the one-minute horn sounding, the Repsol Honda mechanics had exceeded their amount of time to work on the bike, though the situation was resolved in time for Pedrosa was able to join the field for the sighting lap.

Noticeably shaken by the incidents that occurred just a moment from the lap, and running on essentially cold tires, Pedrosa was lapped by the pace car, and ultimately had to start the San Marino not on pole, but instead at the back of the grid. Yes, even before the race started, the San Marino GP proved to be one of the most dramatic rounds of the 2012 MotoGP Championship.

With the signing of Cal Crutchlow for another year with the Monster Yamaha Tech 3 squad, before the Czech GP even got started it was turning the page on another chapter of the MotoGP silly season. The racing too would prove to be pivotal to the Championship. A mix of good and bad weather during the week, Brno would prove to be a dry race, despite hosting a wet warm-up session.

With Dani Pedrosa on form all through Free Practice, the Spaniard’s off in qualifying took him off a step, as he had to ride his “B” bike, which suffered from more chatter. Despite Cal Crutchlow placing second on the grid for the race, the Brit noted what everyone already knew: Sunday’s race would be between Pedrosa and Lorenzo — and he was right.

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.

One of the first race weekends of the season to have consistent weather, race fans seemed all set for some fine MotoGP racing at Indianapolis Motor Speedway this Sunday. The positive vibe would be stricken though, as three riders hit the tarmac hard during Saturday’s qualifying. Out for his home Grand Prix, Nicky Hayden would have to watch the race from the Ducati garage, while Ben Spies and Casey Stoner overcame injuries to brave the breach once more.

With Rossi continuing to struggle on the Ducati, Dovizioso (the man tipped to replace Rossi at Ducati Corse) sitting on the front row with a satellite bike, and Dani Pedrosa topping the time sheets at the pole-position, eager to claw some points back in the Championship from Jorge Lorenzo, the Indianapolis GP at least sounded interesting on paper, though was quite the opposite once it came to actuality.

With the road to the summit of Pikes Peak fully-paved now, riders not only had to contend with learning the 156 corners that comprise the race to the clouds, but they also had to learn the new asphalt sections that were paved after last year’s race. Getting three days of practice and sunshine on the Pikes Peak International Hill Climb course, on Saturday the weather hit the reset button, bringing rain down on the mountain, which made the road very green for racing the next day.

The sun returned for Sunday’s set of races though, with the motorcycles leading the charge up Pikes Peak. As with the previous years, the talk of class records falling was again high on the discussion list, which is unsurprising since Pikes Peak has added new pavement sections each year to the course. Though, with the asphalt now going all the way to the summit, the big question this year was by what margin the records would fall, and in the motorcycle category, whether a new class of motorcycle would dominate the mountain.

With most of the field still comprised of supermoto bikes and a handful of flat trackers, the 1205cc class showed the most diversity in entries, with BMW, Ducati, Harley-Davidson, and KTM all represented. The PPIHC crew isn’t keen on full-fledged sport bikes racing on the mountain, relegating those entries that did show up into the exhibition class. Though many thought the sport bikers would dominate this year, it was the adventure-touring bikes in 1205cc class that would lay siege to Pikes Peak, in more than impressive style.

Laguna Seca has a habit of throwing the Championship a curveball. The epic race between Casey Stoner and Valentino Rossi in 2008 was a prime example, a turning point in the Championship when Rossi halted what looked like the inexorable rise of Casey Stoner. Last year, too, Laguna proved to be key moment in the Championship, when Stoner stopped Jorge Lorenzo’s resurgence with one of the bravest passes in racing for a long time, through the ultra-fast Turn 1. With Laguna Seca the last race going into the summer break, winning or losing at the US GP can have a dramatic effect on the momentum of the Championship.

Whether the same will be said of Laguna Seca in 2012 will only be clear at the end of the season. But it has all the signs of being a significant moment, for more than just the five points Casey Stoner clawed back from Jorge Lorenzo. The race, if not thrilling, was at least tense: there was little between the two men for most of the race, Stoner shadowing Lorenzo closely, snapping at his heels but not quite able to attempt a pass. The turning point came on lap 18. As the leading pair plunged down the Corkscrew, Lorenzo’s sliding rear tire almost threw him out of the saddle. “I closed my eyes during the highside,” the Yamaha man said afterwards, “and I was happy to still be in the seat when I opened them again.”
