MotoGP: Yamaha Debuts Seamless Gearbox at Brno Test – Shift Times 58% Quicker than Conventional Gearbox

By 7 COMMENTS

It had been widely rumored that Yamaha would have some important updates to test at its private test being held yesterday and today at Brno.

The biggest expected update to be tested was a seamless gearbox, but though Yamaha Racing Managing Director Lin Jarvis had hinted they might be testing the new gearbox, it was far from certain.

As the test at Brno was a private one, no media were invited who would be able to verify whether the seamless gearbox was being tested or not.

Fortunately, however, the Brno circuit was allowing visitors in to watch the test. And among those was Pavel, who runs the Czech Valentino Rossi fansite http://www.rossi-yamaha.cz/.

Pavel shot some video footage of the private test – thankfully not covered by the blanket ban Dorna has on all coverage of the official tests – and was kind enough to send us the audio from the recordings.

Armed with that audio, we were able to analyze the sound, as we have done previously (on both the Honda and the Yamaha), to try to judge whether Yamaha was indeed testing a seamless gearbox, and if it was, what advantage it was giving the riders.

MotoGP Engine Usage at the Halfway Mark: Yamaha Struggling, Honda Dominating, & Ducati Managing

By 9 COMMENTS

With the 2013 MotoGP season at its halfway mark, now is a good time to take a look back and examine the engine usage for the teams and riders.

In 2012, with the engine durability regulations in their third full season, the factories appeared to have the situation pretty much under control. The only excitement arose when something unexpected happened, such as Jorge Lorenzo have an engine lunch itself after he was taken out by Alvaro Bautista at Assen last year.

For 2013, the engine allocation was reduced from six to five engines per season. Each rider now has five engines to last the entire season, for use in all timed practice sessions during each race weekend. With three seasons already under their belt, no real drama was expected, yet that is not quite how it has turned out.

Analysis: Ducati’s Non-MSMA Entry Machines for MotoGP – A Great Gamble with the New Regulations

By 16 COMMENTS

At Assen, Ducati MotoGP Project Director Paolo Ciabatti revealed that they too will be offering bikes for non-MSMA teams in 2014. While Honda is selling a simplified production racer version of the RC213V, and Yamaha is to lease M1 engines, the package Ducati is offering could turn out to be very interesting indeed.

Instead of producing a separate machine, Ducati will be offering the 2013 version of the Desmosedici to private teams, to be entered as non-MSMA entries, and using the spec-electronics hardware and software package provided by Magneti Marelli.

Although the current 2013 machine is still far from competitive – at Assen, the two factory Ducatis finished 33 seconds behind the winner Valentino Rossi, and behind the Aprilia ART machine – the special conditions allowed for non-MSMA entries make the Desmosedici a much more interesting proposition.

Honda vs. Yamaha: Cal Crutchlow Helps Explain Why the First Corner Decides a MotoGP Race

By 14 COMMENTS

Jorge Lorenzo has won the last two MotoGP rounds in utterly dominating style. Though his win at Mugello was by a greater margin, the victory at Barcelona was one of the most impressive of his career. Afterwards, both Lorenzo’s team manager Wilco Zeelenberg and Monster Tech 3 rider Cal Crutchlow said of the Barcelona win that it was probably one of the best races he had ever ridden. Lorenzo had made only one mistake, the Spaniard said afterwards, and it was so small it did not even show up on the data.

As he had done at Mugello, Lorenzo ensured that he won the drag race to the first corner, aggressively outbraking Dani Pedrosa to take the lead. From that point, he held the Honda’s at bay until Dani Pedrosa finally broke, the Yamaha man going on to win by nearly two seconds. It was the second race in a row which Lorenzo had led from the start and gone on to win the race.

In fact, all three of Lorenzo’s wins, at Qatar, Mugello and Barcelona, have come in the same manner: Get into the first corner in the lead, push hard in the early laps, and ride as perfectly, and as fast, as possible throughout the entire race. There is simply no one else in the world capable of riding a motorcycle for 25 laps at full speed as well as Jorge Lorenzo at the moment.

As impressive as Lorenzo’s wins have been, the one thing they have lacked is spectacle. There has been no drama, no battles, no need to defend, and the only place Lorenzo has needed to attack has been off the line, an area perhaps aided by the new clutch Yamaha have been using for this year.

Does Lorenzo not enjoy the battle, is he incapable of holding his own in a battle, or is it down to the bike? It is a question which is debated by fans around the world, with an answer apparently hard to give.

Analyzing MotoGP’s Game of Thrones at the Catalan Test

By 8 COMMENTS

Pity poor Jorge Lorenzo. Once again he comes to a test and tops the timesheets, and everyone is talking about someone else. This time, though, he will probably not mind, as he was not really out for glory at the test, just to work on settings before heading to the next test at Aragon on Wednesday. If it isn’t rained off that is.

Lorenzo chose to skip the morning session, preferring to rest after an impressive win on Sunday, but once underway he was quickly up to speed hitting the top three after just a couple of laps, and ending the day on top.

The Factory Yamaha man had been working on setup, but had also tested a new fuel tank. The new tank does not change the weight balance from the current version used by the factory riders, but it does have a slightly different shape to fit under the seat more comfortably and allow Lorenzo to position himself better on the bike.

On the other side of the garage, Valentino Rossi was once again pursuing weight distribution changes to improve his feel with the bike, especially to help him in braking. A more radical change was planned for the afternoon, but a fast crash at Turn 3 left the bike damaged, meaning that plan had to be abandoned.

Rossi returned to the track at the end of the day to test the new rear tire Bridgestone had brought, and was positive about the feel of the tire. The new construction hard rear tire was a clear improvement, Rossi said, and it was good for the hard rear to once again be an option.

So far this year, the only tire that has worked at most tracks has been the softer option, leaving the riders with a de facto rear allocation of just seven rears for a weekend.

MotoGP: Lap Time Analysis from De Puniet’s Suzuki Test

By 12 COMMENTS

Randy de Puniet has completed his first two-day test on Suzuki’s MotoGP machine. The Frenchman flew to Japan directly after the French round of MotoGP at Le Mans, to take part in the test organized at Motegi’s Twin Ring circuit, home of the Japanese round of MotoGP, and a circuit owned by Honda.

Under the terms of his testing contract, De Puniet is unable to say anything official, his manager Eric Mahé telling the French magazine Moto Journal only that the test “went well”. Suzuki did not publish any times from the test or provide any other information, but as the MotoGP test teams from both Yamaha and Honda were present, it was inevitable that times would leak out. German-language website Speedweek claims the scoop, with times also to be published in the Spanish magazine Motociclismo, which is out on Tuesday.

According to Speedweek, the test took place in excellent conditions, with temperatures of 28°C and a dry track. The German website reports De Puniet as having posted a time of 1’47.0 on Suzuki’s new inline four MotoGP machine, though no other confirmation of that time has been forthcoming. In comparison, that is as fast as Honda test rider Takumi Takahashi on the day, and half a second quicker than Yamaha test rider Katsuaki Nakasuga.

MotoGP: Defective Tire Or Setup Error – Why Did Jorge Lorenzo Struggle at Le Mans?

By 12 COMMENTS

Jorge Lorenzo’s disappointing performance at the French Grand Prix at Le Mans has been the cause of some debate. The factory Yamaha man finished a lowly seventh, his worst finish (other than DNFs) since his rookie season in 2008, and finishing off the podium for the first time since Indianapolis in 2011. To say this was an uncharacteristic performance from Lorenzo is something of an understatement.

So what went wrong? Immediately after the race, Lorenzo made it clear that he believed the problem was with his rear tire. He had had no grip whatsoever, and been unable to get any drive from his rear tire.

He told the press afterwards that the only logical explanation he could think of for his problems was a defective rear tire. Lorenzo had been fast in the morning warm up, though it was a little drier then, and the set up used was very similar to then. In 2012, Lorenzo had won at Le Mans by a huge margin, so he could not understand why he was struggling so badly in France.

Bridgestone naturally denied there had been a problem with Lorenzo’s tire. After the race Bridgestone officials told the press that they had examined the tire together with Yamaha engineers and found nothing wrong with it.

In their customary post-race press release, Bridgestone’s Motorsport Tyre Development Manager Shinji Aoki reiterated this stance. “As is always the case in these situations, his engineer thoroughly examined Jorge’s race tyres which were found to be in good working condition,” he is quoted in the press release as saying.

“In addition, I examined the tyre myself and personally discussed the matter with the Yamaha engineers and we all agreed that Jorge’s lack of rear grip was not attributable to his tyre.”

What do we know ourselves? Though nobody is saying anything other than official statements, there are still some clues we can piece together from the data available. The key fact is visible from the race footage, available to those with a MotoGP.com video pass on the official MotoGP website.

The First Steps on Ducati’s Long Road to Redemption

By 35 COMMENTS

“This is the reality,” factory Ducati rider Andrea Dovizioso told the media after finishing 7th at Qatar, some 24 seconds off the pace of the winner, Jorge Lorenzo. Hopes had been raised on Saturday night, after the Italian had qualified in fourth, posting a flying lap within half a second of polesitter Lorenzo.

While Dovizioso’s qualifying performance had been strong, he had at the time warned against too much optimism. The Desmosedici is good on new tires, but as they begin to wear, the chronic understeer which has plagued the Ducati since, well, probably since the beginning of the 800cc era, and maybe even well before that, rears its ugly head and makes posting competitively fast laps nigh on impossible.

The problem appears to be twofold. Firstly, a chassis issue, which is a mixture of weight distribution, gearbox output shaft layout, frame geometry, and to a lesser extent chassis flexibility. And secondly, a problem with engine response, an issue which is down in part to electronics, and in part to Ducati still using just a single injector per throttle body.

Crunching the Numbers: Lorenzo vs Rossi – Marquez, Pedrosa, & Crutchlow – The Race Pace at Qatar

By 17 COMMENTS

Much has been made in the days since the thrilling MotoGP season opener at Qatar of the charge of Valentino Rossi through the field and the pace he ran to catch the group behind Dani Pedrosa.

Speculation has been rife that had Rossi got a better start – and more importantly, got a much better qualifying position – he could have matched the pace of Lorenzo, and taken the fight to him. But just how realistic is the idea that Rossi could have run with Lorenzo at Qatar, and that Rossi could have matched the pace of his teammate? Reality, or just wishful thinking?

Moto2 & Moto3 2013 Jerez Test Preview

By 1 COMMENT

In three weeks’ time, the 2013 season gets underway for all three Grand Prix classes, and motorcycle racing’s winter will finally be over. Before that, there is a week of testing at Jerez, where first the Moto2 and Moto3 classes get their final run out on the track from Monday through Thursday, before MotoGP takes to the track on Saturday, Sunday, and Monday.

Testing at Jerez may be affordable for GP’s junior classes, but it does not come without risk. Moto2 and Moto3 tested at both Valencia and Jerez in February, and while conditions were sunny and dry, if a little cool at Valencia, the test at Jerez was very mixed indeed, with rain disrupting two of the three days of testing. This test looks just as likely to be disrupted by rain: while good weather is forecast for Monday, Wednesday and Thursday, Tuesday looks like being a total washout.

That will leave the riders with two full days of dry testing – for some arcane reason, IRTA has decided to spread the three days of Moto2 and Moto3 testing over four days, with the test starting on Monday afternoon, and concluding on Thursday lunchtime.

There is surely method to this madness, but unfortunately, IRTA does not have a press office, and so nobody to explain it. In the absence of an IRTA – the International Roadracing Teams Association, the official body representing the teams – press officer, the media are left to scratch their heads, speculate, and all too often, concoct explanations for themselves.

Lessons from Austin: Marquez’s Star Rises, Rossi’s Wanes

By 8 COMMENTS

So the three days of testing at Austin are over, and what did we learn? That Marc Marquez is something special? We knew that, though we didn’t perhaps realize just how special. That Yamaha really needs to find more acceleration? This, too, was known, but becoming clearer every time the M1 goes up against the Honda RC213V on track. That Valentino Rossi’s return does not equate to an automatic 8th MotoGP title? We suspected as much.

The first thing that became obvious is that the Austin circuit itself is pretty decent. Valentino Rossi described it as “a typical Tilke track, with corners that remind you of Shanghai and Turkey.” Unsurprising, given that Herman Tilke, who also designed Shanghai, Istanbul, and many other race tracks around the world, was responsible for designing the track.

The input from Kevin Schwantz was helpful, though, making the track more like Istanbul than Shanghai. The circuit has a couple of highly technical sections, where you go in blind and need to have memorized which way the track goes. It is wide, giving opportunities for overtaking and braking, and has a couple of the fast, fast sweepers which motorcycle racers love.

It also has a couple of tight corners, leaving the bike in a low gear with a lot of acceleration to do. This, it became apparent, favors the Hondas, the RC213V strongest off the bottom, and capable of pulling a gap. Acceleration issues will be a problem for Yamaha this year, unless Masahiko Nakajima and his fellow engineers can find some extra grunt out of the corners.

The situation was similar in 2012, but Yamaha was helped by the problems the Hondas had with chatter. So far, the Repsol Honda men have remained silent on the issue, meaning the worst of it is over. Yamaha have their work cut out, and Jorge Lorenzo’s second title defense could be a little too reminiscent of his previous one in 2011.
