Yamaha explain Open M1 test refusal for Jorge Lorenzo

Yamaha denied Jorge Lorenzo’s pre-season request to test an Open class spec YZR-M1 because it made no sense in letting the Spaniard evaluate a bike they had no intention of him racing.MCN exclusively revealed earlier this month that the double MotoGP world champion had requested an Open-spec YZR-M1 test because he felt 24 litres and access to softer compound Bridgestone...

On this one you can see what Jorge problem is: @ 0:00:36, on the brakes at corner entry the Yamaha is moving under him, which is what most bikes would do with a chassis designed for sliding, as does the Honda.

He hates it, doesn't feel safe this way.

What he expect from Yamaha is a total impossibility bar reversing to the 2011/13 chassis which is not what they want; a stable chassis as he likes is never going to brake as hard and late, turn as well or be as controlable on the gas as that of the RCV.

First he needs too much weight on the rear wheel, which means less heat on the front for braking (2013 issues of front grip), then weight plus moment arm equals high rear end inertia and LESS weight on the front equals less front end authority and control.

In short, if the rear departs, it takes over the front which goes very shortly after (Silverstone on in the wet, Assen, Sachsenring in the dry etc, same pattern), if you have access to HD videos of his crashes since 2011 look at them in slow motion and take notice how the front wheel reacts to the rear going out on his bikes.

 How can we tell what Lorenzo wants from a bike when he can ride a bike with one hand tied behind his back better than any of us mortals. To be at Jorges level you have to be able to slide a bike, or ride it to the limit with the wheels in line. His corner speed and lean angle are the best their is out their and to do that the front tyre must be up to temperature. I dont know why he crashed last Sunday but trail braking on a cold tyre makes sense which most riders have been giulty of. All i know is that he has so far been the only rider to take it to Rossi on equal machinary and that was when Rossi was in his prime. Give him a couple of more races and he will be Winning races

Well, apparently he can't do what the others can't either, if you don't have the bike designed and set up for your style it's either you adapt to it or you can't get 100% out of it let alone over-ride it like Marquez does, meaning, taking it beyond the tyre adherence limits, (rear of course) which was commonly known as riding a bike at 110% during the 500 cc era.

For Lorenzo style i will refer you to Yamaha Racing website, News, 28/02/2014 Sepang2 tests:

Massimo Meregalli: “We finished this three day test with some good improvements and were able to make the bike better every day. At the end Valentino was able to make the fastest lap of the day. Jorge continued to have some difficulties, especially because of his riding style". That's low grip levels which is exactly what this issue is about, with new or worn tyres, it's all about grip and how one can control the slides.

As for the way he likes his bike set up: www.cycleworld.com/2013/07/30/interview-with-valentino-rossi-yamaha-engineer-jeremy-burgess/

It's all in there, for more details there have been dozen of articles on the subject since the last link's date, we know he favours corner speed, which means a longer wheel base and more weight on the rear.

This is the opposite geometry than that allowing for better braking, turning-in, braking while turning and acceleration characteristics of a chassis such as the Honda RCV, reason being suspension work and geometry vs weight transfer in the first place.

Mortals with this level of interest in the subject knows that, especially if you take or have taken bikes on a track and have/had to deal with such things, it's not the level of competition, the way things are done is the same from club racing to moto gp, only the level of skills and complexity of the equipment differs.

ps, following your reasoning, moto gp journalist would only be able to report fairy tales and tea-saloon gossip.

ps2. It's not about his ability to win races which he did last year, it's about his ability to get the better of a guy who was consistently faster than him in his first season and retake the title, at Yamaha they know damned well that a repeat of Stoner's dominance is a real probability with Marquez riding the way he did last year.

Jorge to Honda

 DeGrasse, you are right when you say taking Jorge from Yamaha is all win. But if Jorge did go to Honda a) he wouldn't come cheap and b) he wouldn't go unless he had equal billing to Marquez.

Honda could easily build a 250 style bike if they really wanted to.

http://www.redbull.com/cs/Satellite/en_INT/Article/Aoyama-wins-250cc-crown-021242790274601

The Honda was down on power/acceleration compared to the Aprilia/Gilera but had better handling and corner speed. This years improvement in Moto3 shows what they can do if they set their minds to it.

Honda don't work the same as Yamaha. Honda get bored and like a challenge. There is no reason they couldn't turn up at Jorge's first test with 3 engines,5 frames and 7 swinging arms for him to test.  Last year Marquez had a new swinging arm at the 3rd or 4th race to help him at high lean angles. Which leads on to my last comment. At Qatar Marquez was hitting 58 degrees lean angle on the hard tyre. Last year he was regularly hitting over 60. Plenty of edge grip there.

 Big Big difference between doing a couple of track days and doing MOTOGP. As James Toseland once said he could go to a track day and be quicker than any one their even if he rode one handed. As he said this wasnt being big headed this was just a fact. So doing a couple of track days does not make you an expert on MOTOGP, the riders, or the bike set up. Leave it to the experts please
