WHY CRASHED JORGE LORENZO IN MISANO?

Why crashed Jorge Lorenzo in Misano? - Technical Explanation
The reason of the crash was said by the same Jorge Lorenzo in the cold tyres “It was very difficult to warm up the tires and get used to the new feeling with the slick”  “I did not pay attention to that corner that is left after many on the right. There must also be careful with the dry.”

But because the crash occurred at that point of the track, after he had completed nearly a lap and the tires albeit slightly they would have to be warmer than the first corners after the exit of the pits? Only driving error or there also a technical explanation?

We see with our software SET-UP Bike and to our model for the calculation of the temperature of the tyres, to understand more.

Insert into the software in addition to the technical data of a MotoGP bike, weight and height of Jorge Lorenzo, and the quantity indicative of liters of gasoline remained in the lap of the crash.

Grip on the track at the moment of Jorge Lorenzo crash - SET-UP Bike  Now we have to set the grip level that there was at that moment on the track, for this we refer at the time made from Marquez in the lap after him pit-stop, which took place two laps before of that of Lorenzo, and we set in the software a grip that allows to virtual rider to do a time equal to that by Marquez on the first lap after the pit exit.

At this point we can start the simulation.
From the results calculated by SET-UP Bike for first we look at theperformance analysis, which shows us what limits the performance in the various points of the track.

At the point where the crash occurred, just begins the change of direction after hairpin right, the problem becomes adherence, then regardless of the temperature of the tires this is in itself already a critical area.

But let's see what happens to the temperature of the tires during the lap. We use our calculation model and given that depending on the lean angle, work different parts of the tyres, analyze what happens to the temperature the tire into three distinct areas, the left side, the middle and the right. Three areas of analysis tire temperature MotoGP - SET-UP Bike
Average surface temperatures left-center-right of front tyre MotoGP - Misano - SET-UP Bike  From the analysis of average surface temperature in the three zones is seen in very clearly that in the point of the crash, the side left of the tyre reaches its lowest temperature compared to all the other points of the circuit, then as soon as Jorge Lorenzo has performed the change of direction and then began working the left side of the tyre, he found himself with tyre temperatures many lower compared to a few meters before where the tyre worked on the right side and at the middle.

Grip trend depending of the tyre temperatura MotoGP - SET-UP Bike  Since as is it is known the tires offer a different grip according their temperature, as soon as Jorge Lorenzo has performed the change of direction has found a grip sharply lower and hence the loss of adherence was clear and not controllable.

So certainly there was the error, but it was mainly in overlook this technical aspect very significant until the tires did not reach a temperature that will mitigate the problem.
From this analysis it is clear that sometimes behind a mistake there is a technical explanation that can help us to understand it, but it is equally clear that today with the technology and software appropriate you may have some informations in advance that can help rider and team to avoid mistakes that could be very importants!
