Will Cheats Prosper? How Inertial Platforms Can Manipulate The Spec ECU, And Is It Worth It

The move to a standard electronics package, both hardware and software, had raised the hopes of fans, teams and organizers that a more level playing field could be established, and costs cut. The ideal sketched by Dorna and IRTA when the plan first came out has proven to be impossible to achieve. The manufacturers have resisted calls for a completely spec hardware and software package, and so a compromise has been reached. The ECU hardware and software will be built, updated and managed by official electronics supplier to MotoGP, Magneti Marelli. Factories will be free to choose their own sensors, but those sensors will have to be homologated, and made available to any other manufacturer which wishes to use it at a reasonable price.

Not quite all of the sensors, however. In response to a request by the factories, the inertial platform will remain what is called a free device, i.e. any manufacturer can choose to use whichever inertial platform they like, without first submitting it for a approval to Dorna, or making it available to their rivals at a price. The inertial platform is a crucial part of the electronics package, consisting of a collection of gyroscopes and accelerometers, which describe the attitude and motion of the bike. In other words, the inertial platform tells the ECU what lean angle the bike is at, whether it is braking or accelerating, how hard it is corner, etc.

Giving manufacturers the freedom to use their own inertial platforms has created a lot of suspicion. Because the inertial platform plays such a pivotal role, there have been accusations that some manufacturers, especially Honda and Yamaha, wish to use their proprietary units to circumvent the rules. There are good reasons to build some intelligence into inertial platforms, as such intelligence can increase accuracy, and therefore help the ECU software perform better. This is the reason the factories give for wanting their own inertial platform; experience with the spec unit used by the Open class machines has shown it to be insufficiently accurate.

But the intelligence built in to the inertial platform could go well beyond just improving accuracy. By including a powerful processor in the inertial platform, one which could be programmed by a manufacturer with their own software, and their own algorithms and strategies, the inertial platform could hypothetically be used to modify the strategies being used by the unified software in the spec ECU.

Jorge Lorenzo Sprains Shoulder While Training, Will Race In Japan

Jorge Lorenzo has sprained his left shoulder in a training accident. The four-time world champion was training on a minibike with some other riders, when he fell heavily on his left shoulder. The pain was severe enough for him to travel to a medical center in Barcelona, where he was diagnosed with grade 1 sprain of his left shoulder. Grade 1 sprains are the lowest level injury, a mild sprain. Sources speaking to both Motocuatro and classified the injury as "not serious, nothing to worry about."

Lorenzo is already underway to Japan, and intends to race at Motegi, the first of three back-to-back flyaway races. How much the injury will hamper him remains to be seen, but given the mild nature of the injury, it should not trouble him too much. Motegi does have a lot of heavy braking, but it is mostly for right-hand corners. From there, the circus heads to Phillip Island, which is a left-hand circuit, but which does not feature much heavy braking. Then to Sepang, which is a mixture of braking for both left and right handers.

Marc VDS Confirms Tito Rabat To Race In MotoGP For 2016

The first piece of the Marc VDS / Estrella Galicia puzzle has officially been put in place. Today, the team announced that Tito Rabat will be moving up to race for the team in MotoGP for 2016. Rabat will take the place of the departing Scott Redding, riding a factory-backed Honda RC213V. Rabat got his first spin out on the bike on Monday after Aragon, ostensibly as a reward for winning a title, but the suspicion was always that the team had done this to allow Rabat to get at least a feel for the bike ahead of next year.

That this was the only announcement from the team is something of a surprise. The original plan, understands, was to announce the entire line up all in one go. This was intended to make life easier for the team and its many sponsors, allowing them to coordinate their announcements. However, when asked about progress on this, team sources made it clear that the intention was still there, but that getting all of the deals done, contracts signed and sponsors ready was a little like herding cats. 

More news is likely to emerge from the Marc VDS team in the next week or so, including announcements of Jack Miller to race alongside Rabat, on similar material, the arrival of Franco Morbidelli in Moto2, and Enea Bastianini partnering Jorge Navarro in Moto3.

Below is the press release from Marc VDS on Rabat's deal:

Silly Season Loose Ends: Aspar, Marc VDS, Moto2 and Moto3

Aragon was a busy time for the riders and managers in all three Grand Prix classes. Wrapping up contract negotiations before the circus heads east for the Pacific Ocean flyaways was high on the list of priorities, though not everything ended up getting sorted before the teams packed up at Aragon. Plenty of agreements were reached, however, as we shall see below.

Though most of the loose ends have been tied up in MotoGP, a few question marks remain. The Aspar team was one of those question marks, which came much closer to a conclusion at Aragon. The original plan was to have Jack Miller join the team, bringing his crew with him, and covering most of the cost of riding, but various obstacles prevented that from happening. Money was a major factor, in part the amount Aspar were willing to pay to have Miller in their team, but perhaps a bigger factor was being left with Hondas.

The Open class Hondas have both been a huge disappointment for all of the teams which have run them. The 2014 RCV1000R was massively underpowered, and was getting blown away by the factory bikes along the straight. To remedy that situation, Honda offered the RC213V-RS, a cheaper version of the factory RC213V, but without the seamless transmission and using the spec electronics. That bike has also not been competitive, perhaps in part because it is a stripped down version of the original. "This bike was designed to use a seamless gearbox," Nicky Hayden explained last weekend. "You can't get the best out of it without one."

Rossi needs 'stuff' to happen

Cue the Jaws theme tune, because Jorge Lorenzo is coming to get Valentino Rossi. The Spaniard took a nine-point chunk out of Rossi’s championship lead at Aragon, at which rate he will lead the championship at Phillip Island, with all to play for in the final two races at Sepang and Valencia.

Rossi always knew this moment was coming; indeed he’s been there before. Way back in June 2009 he likened Lorenzo and Casey Stoner to sharks, circling around him in the water, ready for the kill.

“They look at me with some blood flowing and they think, ‘Okay, now is the time’,” he said. “If I am not strong, they will eat me in one bite.”

Six and a bit seasons later he is in exactly the same position. So what will it take to repulse Lorenzo’s latest attack?

Marc Marquez Fractures Left Hand While Training - Fit For Flyaways

Marc Marquez has broken his left hand for the second time this season. While out training on a mountain bike, the reigning MotoGP champion fell, and fractured the fifth metacarpal of his left hand. He underwent surgery on Wednesday morning at the Dexeus Institut in Barcelona to fix the bone. Dr Mir inserted a titanium plate to stabilize the bone.

Marquez will start physical rehabilitation immediately, and intends to fly to Japan and contest the three flyaway rounds of MotoGP, at Motegi, Phillip Island and Sepang.

This is the second time he has injured his left hand this year. Before the Jerez race, Marquez crashed while riding dirt track, and fractured a phalange bone in his left pinky finger. This injury is to the same finger structure, the fifth metacarpal being the bone in the hand which the pinky finger is connected to.

Below is the press release from HRC on Marquez' injury:

Aragon Michelin Test - Crashes Show French Tire Maker Still Has Work To Do

The day after an intense race at the Motorland Aragon circuit, MotoGP held its first full Michelin tire test since Sepang this year. The track was open to any teams wishing to give the Michelin tires a spin, or work on the setting of their bikes. Fourteen riders elected to make use of the opportunity, including both Repsol Honda riders, the Tech 3 Yamaha duo, both LCR Honda riders and the Aprilia men, along with Scott Redding, Aleix Espargaro, Danilo Petrucci and Valentino Rossi.

Michelin had brought three rear tires and four front tires to Aragon, keen to get some data from the circuit, as they have not had much testing at the track, and very little in the dry. That they needed the data became clear in the morning, as cold temperatures caught a number of riders out, including Bradley Smith, with several crashes happening. Those problems disappeared in the afternoon when the temperatures rose.

2015 Aragon Sunday Round Up, Part 1 - Of Deceptive Speed, Unforced Errors And A Championship Reopened

Just when it looked like the three Grand Prix championships were getting closed to being wrapped up, along came Aragon. The three races at the last European round before the Pacific flyaways left the title chase still open in all three classes. The outcome in both Moto2 and Moto3 still looks pretty much inevitable, but a win by Jorge Lorenzo in MotoGP meant that the battle for supremacy between the Spaniard and Valentino Rossi is anything but over. The Moto2 and Moto3 crowns may end up being handed out at Motegi, Phillip Island or Sepang, but the championship fight for MotoGP will most likely go all the way to the last race in Valencia. That may be hard on the fans of the two riders involved, but for MotoGP as a series, it is great. The pressure and the tension go up with every race, and makes watching an ever greater joy.

Jorge Lorenzo's victory at Aragon was taken exactly as he has taken his previous five wins: the Movistar Yamaha rider got the jump off the line, led in to the first corner, and tried to make a break. The timesheets bear witness to just how hard he was pushing. Breaking it down into the four timed sectors which go to make each lap, Lorenzo set his fastest split times in the third and fourth sectors on his first lap, and followed that up with his fastest splits in the first and second sectors at the beginning of lap two.

If his intention was to intimidate the opposition – and clearly it was – then it worked. Marc Márquez, who had got caught up off the line behind Andrea Iannone, stuffed his Honda RC213V past the Italian's Ducati into Turn 7 on the first lap, then pushed to close the gap to Lorenzo on the second lap. He caught the Yamaha as they powered through the long left hander which comprises Turns 10 and 11. Trying to make up ground he pushed a little too hard, losing the front on the way into Turn 12. The only man who had looked like he had the pace to match, and perhaps even beat Lorenzo at Aragon, had taken himself out of contention. Now Lorenzo was left to ride, and to reign, unopposed.

2015 Aragon MotoGP Warm Up Result: Marquez Leads Lorenzo

Marquez was fastest throughout, pulling an extra gap on his final lap. There was a minor incident in pit lane, when Valentino Rossi pulled across Jorge Lorenzo's exit and accidentally blocked his path while they practice wet bike swaps. Lorenzo came in and practiced that swap a second time in the session.


2015 Aragon Saturday Round Up: Can The Weather Save The Championship Lead?

The last two races have followed a familiar pattern. On Friday and Saturday, Jorge Lorenzo has laid down a scorching pace, which his rivals – and more importantly, his teammate and rival for the 2015 MotoGP title, Valentino Rossi – have been unable to follow. Lorenzo's name was penciled onto the winner's trophy, and his grip on the MotoGP class looked secure.

Then on Sunday, everything changed. The weather gods intervened, rain lashed down at Silverstone, then started and stopped at Misano, throwing the race into disarray. Both times, Valentino Rossi handled the conditions better than Lorenzo, gaining big points in both races. At Silverstone, Rossi won comfortably, while Jorge Lorenzo struggled home in fourth. At Misano, Rossi rode a tactically poor race, but still managed to come home in fifth. Lorenzo got caught out by the pace of Scott Redding, failing to understand that the Marc VDS rider had already been out for several laps and had his tires up to temperature and his brain up to speed. The Movistar Yamaha rider tried to stay with Redding, and paid the price when he turned left after a long series of rights, crashing out and scoring zero points.
