Most of MotoGP's top men have said they are suffered serious chatter problems when trying to put in a fast lap on Bridgestone's softer compound tyres in qualifying at Sepang today.

Even poleman Jorge Lorenzo said it was making life difficult as he set a new circuit best record while Nicky Hayden complained his hands were still tingling some time after the session finished.

“We made a very good lap at the end of the session with the new ‘qualifying’ tyre. In the middle of the practice we struggled a little bit because we had a bit of chattering and the rear tyre wasn’t working as well as it had been in the morning session. We need to still work a little on our pace as it’s not extremely good yet but we have some options for tomorrow," said Lorenzo.

Dani Pedrosa added: "It was hard because we had a lot of chattering this afternoon and it was very difficult to get a clean lap as in some areas the bike was chattering too much, even on the straight! Nevertheless, we managed to get on the front row again and second position is good."

"It hasn’t been an easy day. In qualifying I lost some time due to a couple of issues I was having with the clutch and rear brake. Then we made a few little changes and got going better, but I had so much chatter that both of my hands are still tingling. I think a lot of guys are dealing with it, but it’s really making it difficult for me in the fast corners," said Hayden.

Stefan Bradl added: "This morning we have tried to find the right way to reduce the chattering because I could not entry the corner and we are losing too much in the middle of the corner and we are struggling to find the solution because we never had such a big chatter issue in the past.

"In these conditions I do not have enough confidence and this cost me a lot of time that’s why I am too slow in those areas. In the beginning of the session on used tyres it looked like we were capable to reduce the chattering problem but as soon as we went out on new rubbers the problem was still there."
