Cheating in motorsports is as old as the sport itself. Whenever powered vehicles gather together to race each other, then someone, somewhere, will try to gain an advantage, either within the rules or, if that is not successful, outside of the rules. In all classes, and at all times, teams, engineers and riders have all tried to cheat in one way or another. Even the imposition of a spec engine in the Moto2 class hasn’t prevented teams trying to cheat, and the paddock is awash with rumors regarding which teams are cheating and which teams are not.

The finger of blame is inevitably pointed at the most successful riders, and in recent months, it has been pointed mainly at Catalunya CX rider Marc Marquez. Marquez has a number of strikes against him, making him a popular target for rumors of cheating; firstly, Marquez is Spanish, and as Moto2 is a Spanish-run series, the non-Spanish teams are all fervently convinced that Spanish teams are not monitored as closely as they are.

Secondly, Marquez has the backing of Repsol, one of the more powerful sponsors in the paddock, exerting influence not just over Marquez’ Monlau Competicion team, but also over the much more important factory Repsol Honda team; the power of Repsol, the gossips suggest, exerts undue influence on the policing process. Thirdly, and most obviously, Marquez is fast, almost suspiciously so. The Spaniard’s bike is always one of the fastest through the speed traps, and accelerates hardest off the corners. His team put it down to hard work at finding exactly the right set up for Marquez to excel. One of the lighter Moto2 riders on a well-prepared bike, ridden by a fast and talented rider? That, Marquez’ supporters argue, is reason enough for him to be fastest.

To find out more about the situation, and what Dorna and the scrutineers are doing to address these concerns, I spoke to Race Director – and formerly Technical Director – Mike Webb at Estoril. I passed on the concerns that others had expressed to me about cheating in Moto2, and he explained to me exactly what Dorna are doing to monitor the bikes and ensure that cheating is kept to an absolute minimum, and that if it is happening, it does not pay. Here is what Webb had to say:

One of the most fascinating areas of MotoGP is the relationship between rider and crew chief. The way that those two individuals communcate and interact can be the difference between winning championships and riding around mid-pack. Riders need a massive amount of talent to go fast, but they also need to understand what the bike is doing underneath them and be able to communicate that to their chief engineer. Likewise, crew chiefs have to have a solid grounding in race bike physics and an understanding of how to make a machine that is capable of lapping very fast, but they also need to be able to listen to what their rider is really saying, and understand what he needs to allow him to go faster.

It is a subject that has fascinated me for a long time. At Estoril, I had the chance to interview Jorge Lorenzo together with his crew chief Ramon Forcada. 2010 World Champion Lorenzo came into MotoGP off the back of two 250cc World Championships in 2006 and 2007, and was joined by Forcada, a 20-year veteran of the Grand Prix paddock, in the factory Yamaha team. Both men were known for their ability, but they had to find a way to work together to get the best out of the relationship, and out of the Yamaha M1. Here is what they had to say about how that relationship works:

As I listened to Casey Stoner explain how he rode around the flu, a chattering bike, and his latest bout with arm pump to stay just far enough ahead of Jorge Lorenzo to win the final GP at Estoril, I couldn’t help but wonderi how Lorenzo sees his future. It can’t seem as bright as it did at the end of his nearly perfect 2010 season.

Lorenzo had succeeded in mounting so much pressure on his Fiat-Yamaha teammate that Rossi started crashing, and ultimately left Yamaha for Ducati, rather than remain on the same team as the Spaniard. But for Lorenzo, that only exchanged one demon for another, this one in the form on Stoner on a Honda — a combination that now appears pretty much unbeatable over the course of a season.

If there’s one lesson we can take from Sunday’s race at Estoril, it’s this: “I’ve always said we know Casey’s the guy that’s the fastest guy in the world. Maybe over the seasons he hasn’t put the championships together, but by far he’s the best guy in the world.” Cal Crutchlow is not known for mincing his words, and his description of Casey Stoner pulls no punches. But given the fact that Stoner only managed to win the Portuguese round of MotoGP by a second and a bit, is that not a little exaggerated?

Here’s what Stoner had to say about it, when I asked him if winning with the chatter he suffered – even on the TV screens the massive vibration front and rear was clearly visible – made him more confident about the level of his performance. “It gives me a lot more confidence. That’s the thing, you know, with arm pump, with the chatter problem, I’ve been feeling like crap all week, and my body’s not as good as I normally am, and we still managed to hang on, we still managed to be clearly faster than the others at the end of the race.”

With fair weather conditions over Estoril, MotoGP dodged the rain bullet and had a dry race for Sunday’s Portuguese GP. Noting that the Ducati rain dance had failed, our attention shifted to the inter-Yamaha rivalry that is brewing between Ben Spies, Cal Crutchlow, and Andrea Dovizioso. With the American ailing in the factory Yamaha Racing team, both Crutchlow and Dovi are keen to take his spot for next season, as virtually all of the rider contracts are up this season. Cal has so far shined brighter than the Italian, starting today again on the front row.

With that battle set to go throughout the 2012 MotoGP Championship, more pressing issues included the absence of Colin Edwards, who broke his collarbone after getting struck by Randy de Puniet’s crashing Aprilia ART. Having won at every track except Estoril, the last bit of business for the Portuguese had to do with Casey Stoner, who was looking to complete his mantle of circuit wins with Estoril.

With MotoGP reducing its races on the Iberian Peninsula for the foreseeable future, this weekend marked the last time the premier class would race in Portugal. Click past the jump for race spoilers and results.

The rain, which has been chasing motorcycle races around this season, finally got bored and moved off on Saturday, giving the track at Estoril a chance to dry. The final corner, which proved so treacherous on Friday, was greatly improved – and made even better by the addition of a cone on the inside of Turn 13, marking where the wet patches were so the riders could take a line inside them. But the wet patches were still there, with water apparently seeping up from the ground to be sucked to the surface. The repairs to the track had been half the problem; the new asphalt was still so fresh that the bitumen was sucking up water from below. Not a lot the track can do about such a problem, and rather cruel to be punished for trying to fix the track in the first place.

While their resurfacing attempts may not have paid off as intended, the circuit management’s bargain basement approach to ticket pricing made a huge difference. The track was busier on a Saturday than any time I have ever been here, with many fans deciding that for the price of a tank of gas and a cheap hotel, they would head for Estoril. With tickets selling for between 2 euros for the cheapest single-day entrance to 20 euros for a three-day grandstand pass, the entertainment is also a little limited. Jumbotrons around the track are few and far between, the only one I have seen has been opposite the main grandstand. But for 2 euros, and with some great seating around Estoril, who is going to complain?

Colin Edwards has broken his left collarbone in a crash during qualifying for the Portuguese MotoGP round at Estoril on Saturday. The NGM Forward rider was knocked off his bike in the latter part of qualifying practice, as he cruised around off the racing line. Randy de Puniet lost the front of his Power Electronics Aprilia machine, which slid along the track and hit Edwards’ Suter BMW. Edwards fell heavily, suffering a mild concussion and injuring his collarbone in the fall. De Puniet was taken to the medical center, where he was diagnosed with bruising to his finger, and general soreness.

With mixed weather at the Portuguese track, MotoGP riders headed out for their last qualifying session at Estoril for the foreseeable future. With the rain making a brief appearance, riders had to contend with changing conditions, though the biggest disruption to the qualifying session was the red flag stoppage for an injured rider.

With a congested track at Estoril, lapped bikes played a crucial element for riders trying to get in a flying lap. As such, the order for Sunday’s racing grid has some surprises from GP fans. Spoilers and qualifying results for the 2012 Portuguese GP are after the jump.
