Takes Master Camp riders to Misano

Makes Statement0 Comments

VR46 AcademyThe Yamaha VR46 Master Camp riders spend the day on the nearby Misano circuit for some asphalt laps on Yamaha YZF-R3 bikes. The pupils ride against Rossi, the VR46 Academy Riders and other guests, before being given some clear track time for themselves in a timed practice session.

Again another great day together with the riders of the Yamaha VR46 Master Camp. This time we found ourselves at the Misano World Circuit, and these were three hours of very intensive training. Some of the VR46 Academy riders have followed the Asian riders on the track and at the end of the day I saw them riding really well. I too have crossed some of them on the track during training and I was impressed with how well they are picking up on our teachings. [Friday] is the last day of Master Camp. We will end this very exciting week in a really nice way: on track with minibikes!

Software caused engine failures

Makes Statement0 Comments

Yamaha engineers say that a software malfunction caused Lorenzo and Rossi’s engines to overrev and be destroyed. The team says that there were no changes made in the usual setup, and the entire blame lies with the spec software that didn’t behave as expected.

Valentino‘s failure was caused by an accidental over rev in acceleration that occurred jumping over a crest with full throttle at the end of the straight. This failure was not in any way related to the mistake made by Valentino at the San Donato corner on the lap before. There were no special mapping settings used for Mugello; we used the same precise mapping as always. We have now withdrawn both engines from the allocation for the season. We have learnt from this incident and already modified the rev limiter setting, so it will be OK in Catalunya. As a precautionary measure, the other engines used by both Valentino and Jorge in Mugello will be used only for practice sessions, until their life cycles are completed…We have already devised a countermeasure, so we are confident that the failures in Mugello will not recur.

Yamaha suspects over-revving

Makes Statement0 Comments

Yamaha say that the most likely cause for the Rossi and Lorenzo engine failures was the undulation on the main straight of the Italian circuit. At that point, the rear tyre – spinning at around 380 km/h in the air – loses grip, leading to an increase in revs per minute for the engine. Rossi’s engine failed after only 500km. Source:

That, combined with this year’s electronics, which are less sophisticated and precise, probably had an influence in the ignition cut-off…Valentino was running behind Jorge all the time, and that probably meant he had no clean air to cool down the engine.. Running in his slipstream meant Rossi’s bike reached speeds it had not managed during the weekend.

Yamaha promises Lorenzo, Rossi equal treatment

Makes Statement0 Comments

Yamaha’s Jarvis says Lorenzo will receive the same treatment as Rossi, other than when it starts working on its 2017 MotoGP bike.

For the rest of the season, our mission is the same as his mission. There couldn’t be a better way to conclude this period of Jorge with us going out as champions. We will give our maximum amounts of equal support to Valentino and continue to provide him with development parts throughout the year. Of course if we get to a moment, for instance maybe like [testing after August’s race at] Brno, where we will bring the prototype of the 2017 bike, that’s a different story…It’s only when it gets to being truly something that we will not use this year, then obviously we will restrict the information on that.

Jarvis also says the relationship between Rossi and Lorenzo changed after the Sepang clash with Marquez.

Prior to Sepang, we’d had Jorge and Vale back together for three-and-a-half seasons. Honestly the relationship had been going very well. Of course, they always remained competitors of each other but the team co-existed and we interacted very well and very freely with each other. After Sepang that changed, this is an absolute fact.

Zeelenberg: Win more titles with Yamaha

Makes Statement0 Comments

Zeelenberg says Lorenzo should stay with Yamaha.

This will be his own decision and it won’t be just one factor. It is true that Jorge [has a strong package at Yamaha] but I can also imagine all competitors at a certain point want to do something else. Looking at that, he has been at Yamaha for eight years, there is a possibility he will [leave]. But I hope of course he is clever enough to stay with Yamaha and to win another two titles – maybe three [including this season]…The race was tight. I expected Maverick [Vinales] there as well, but anyway it was nice to see a group battling…When Andrea was in front, he was fast but the pace was dropping two or three tenths. This is the difficult point, to keep ‘55.4-5 lap times. The rest were able to follow, but Jorge set the benchmark and was able to make another step when the fuel level dropped to escape. This is his personality and character.

Yamaha accelerated Rossi’s contract decision

Makes Statement0 Comments

Despite Rossi saying that he would wait “five or six races to decide” about a two-year contract extension with Yamaha beyond 2016, the timing was changed by team-mate Jorge Lorenzo’s goal of having a new deal secured before the first race. Rossi signed in Doha. Rossi:

I thought in my mind to wait some races, I want to see if I am competitive. Also because usually it is like this, you decide around June. I spoke with Yamaha after the test and they said to me that they are very happy if I continue. In my mind I wanted to continue. The contract more or less was already ready. They said to me, ‘why wait?’ and I said, ‘I agree’, so we did it.

Yamaha’s Jarvis:

I think his expectation and our expectation is most likely this will be the last contract in MotoGP, I guess. But never say never, as we have learned from his career up until today.

Yamaha: Rossi did not kick Marquez

Makes Statement0 Comments

Yamaha issues a statement refuting claims made by Honda that Rossi kicked Marquez.

Yamaha would like to express its disagreement with the words that have been used to report on the incident between riders Valentino Rossi and Marc Marquez. Both press releases included words that accuse Valentino Rossi of kicking Marc Marquez‘s bike that is something not proven by the investigation of the Race Direction.We therefore reject the wording used in the said published statements that do not correspond with the findings of the Race Direction. Yamaha has no wish to enter into further discussion regarding this unfortunate affair and our desire is to conclude the 2015 MotoGP season in the best possible way. We go to Valencia with the clear intention of trying our best to win what we hope will be a memorable final race with all riders and teams competing in an exemplary sportsmanlike manner befitting the top category of motorcycle racing.

Explains appeal

Makes Statement0 Comments

Yamaha Motor Racing Managing Director Jarvis explains Rossi’s appeal.

Our job as a team is to protect the interests of our riders, so while we cannot deny that Valentino’s move is not the sort of move that we want to see in MotoGP, at the same time we feel the penalty is quite harsh, especially when Valentino is not normally a dirty rider. He’s not a rider that creates issues or problems for other people. As a team, we appealed to the FIM and the first decision of the race control. They heard him, also consulted race direction, consulted Marc Marquez and Honda, and finally after a period of 45 minutes we have the results of the appeal, which was rejected. The original penalty of three points against Valentino stands, and in the process of appealing, if the FIM steward rejects your appeal and agrees with the original decision, it is no longer appealable – it becomes final. It’s case closed. That means now that Valentino Rossi will go to Valencia with this penalty.

If anything, knowing him [Rossi], this will probably make him more motivated to come back and to try to do another memorable season like this. And the championship isn’t over – you have to keep that in mind. He has a seven-point lead, and while he’s at a massive disadvantage starting from the back, in racing anything can happen. You never know if he can salvage something. Anything can happen.
