MotoGP star Valentino Rossi gave a 'colourfulꩵ' description of his surprise at Bridgestone's decision to go ahead and change the rear tyre specification.

Both the 2013 and 2014 specification rears had been evaluated during the first Sepang test earlier this month, af⛦ter which it was decided that only the 2014 tyres will be made available.

"The general consensus is that our 2014 specificatio👍n tyres are working well," Bridgestone's Shinji Aoki had comཧmented. "However, there is still a lot of work to do to help the teams get the most out of our new generation of tyres before the season starts."

Following the opening day of this week's return Sepang visit Rossi, Yamaha team-mate Jorge Lorenzo and Ducati's 💝Andrea Dovizioso were among those who spoke of a general lack of grip - especially edge grip - with the 2014 tyres, something Rossi suspects is due to a stiffer construction.

Rossi, who set the seventh fastest lap time, exp﷽lained: "The 📖big issue for us at this test is to try and adapt the M1 to the new tyres, because in the first test we had some problems with the 2014 tyres.

"Especially with the soft tyre. But the situation is like this. They have already decided [to change the tyres] so we have to adap༒t the bike.

"Todಌay we worked a lot on the soft and it was already better - not very good like the tyre of last year, but not so bad."

Asked by wuqian0821.com if he had been surprised by the decision to change to the 2014 tyres, given the i෴ssues he and some others reported at the first test, Rossi replied:

"Yes. As always... Something happened that we cannot understand [laughs]. We just understand when it is already done. So when you are already f**ked! And it is veryᩚᩚᩚᩚᩚᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ𒀱ᩚᩚᩚ bad when you are f**ked and you don't feel nothing before - it is a bad surpri🔴se [laughs]! But anyway it is like this."

Lorenzo - who was fifth fastest on Wednesday - may have used tamer languag🏅e, but the former world champion appeared even more disappointed than his team-mat🙈e.

"We don't find any solution for the [2014] tyres that Bridgestone gave to all th🃏e riders. It seems that for Yamaha it is much worse and they don't want to provide other tyres," he said.

"At the moment we are trying everythi🅘ng - all the set-ups we can - but the feeling is always the same on the track."

The Spaniard added: "We are trying to speak to Bridgestone to make them change the tyre, but at the moment they have a very closed mind about that and they don't want to change. They think this tyre is safer. For me it is the opp🌳osite. It is more dangerous."

Despite his dislike of the new tyres, Rossi believes he had the pace to claim a top three place on the Wednesday timesheets, having finished just half a second behind surprise leꩲader Alvaro Bautista (Honda Gresini).

"At the end I am down in the ranking because I didn'tꩵ put in the soft tyre at the end, because we were concentrating with the hard tyre to☂ do a long run - ten laps - because of the problems at the last test.

"I am♔ seventh, but if I used thဣe soft I think I could have done a 2m 0s, so inside the first three.

"Also with the rhythm, I w𒈔as constant. I did some good lap times. I am quite happy, but we have to go fast. Especially for Marquez."

Repsol Honda's reigning champion Marc Marquez, who dominated testing earli🌳er this month, is missing this week's outing 𝓀after fracturing his leg in a training accident last week.
