Movistar Yamaha’s Valentino Rossi is complaining about a lack of corner entry speed at the Motorland Aragon MotoGP round but is mystifed as what is causing the problem and how to fix it.

The Doctor, who tried all combinations of tyres today, is languishing down in tenth place on the combined timesheets, a full second slower than Marc Marquez in second place and says there is a lot of work to do tomorrow.

“Today is not very good, I am not very satisfied, is a difficult day. Always here in Aragon with the Yamaha is a bit difficult because we suffer about the rear grip so is tough to keep enough good corner speed that is usually our strong point because the rear slide too much,” said Rossi, speaking at Aragon.

“We try to do something but we don’t fix a lot. Anyway, is an important day for take some data to understand which way we improve. I try all the tyres and it will be a difficult choice. At the end I was with the hard rear but in acceleration it spin a bit too much, we have to decide the front.

“We don’t understand the spin. The problem is until you have the slide and spin in acceleration the bike is fast, like in Misano. The problem here is when you brake and enter, the bike move and you cannot bring enough speed into the corner. Sincerely why, I don’t know.”

Even though both Andreas Iannone and Dovizioso have put in fast laps today, Rossi believes over a race distance they have the same pace as the Yamahas but the Hondas are some distance ahead.

“The Ducatis have the extra soft which help them very much but Iannone in these last races ride very well. I think about the pace they are very much like us. The Hondas are the only bikes that are able to stay in the 1’48s pace and also Dani is very fast here, he is not so far from Marc. They are the bigger problem.”
