Jorge Lorenzo says sole Friday practice session did not show true Aragon pecking order

A power failure at the circuit meant that second practice was cancelled, and Lorenzo reckons track conditions would have changed considerably in the afternoon - making the practice one results deceptive. The session had seen Yamaha rider Lorenzo in second place, just under half a second behind pacesetter Dani Pedrosa's Honda.

"This morning we started in a good direction, finishing second just four tenths slower than Dani who was top," said Lorenzo.

"It's too early to make too many conclusions because the track is too dirty so tomorrow will be the real day to see who is fastest.

"We are very disappointed to not be able to make the second start, we have so many things we wanted to try but at least we have an extra half an hour tomorrow to take profit from."

Lorenzo's team-mate Ben Spies was only 11th on the timesheet, but had been in the top three at one stage. The American said he only lost ground because other riders found the hard tyre more competitive at the end.

"This morning was actually quite a good session for us; we were up to third position and then we opted not to change tyres and work on the set-up," he said.

"It seems everyone else tried the harder tyre in the end which worked a lot better so we're looking forward to using that. We picked which set up we are going to move forward on so the end result of the session was definitely not what the bike is capable of.

"Tomorrow should be good. I'm annoyed about this afternoon, it's no one person's fault but it's frustrating."
