After going fastest in the wet yesterday, Stefan Bradl was in a similarly dominant mood in the dry as he set the quickest time on Friday morning. At one stage, the German was over a second ahead of the rest of the field and although that gap was closed later in the session, he still had a comfortable margin over the chasing pack.
Bradl's best lap of 1:39.488 was a full half a second quicker than anybody else, with Scott Redding second fastest on a 1:40.054. The Briton qualified on the front row at Silverstone for the first time this year and will fancy his chances of doing so again later today.
Besides Bradl, the intermediate class was typically close, with Aleix Espargaro was third fastest on a 1:40.207, and just two tenths of a second covering the next five riders behind him. They were led by Michele Pirro in fourth with fellow countryman Simone Corsi in fifth.
Bradley Smith was sixth fastest as he continued the strong pace that took him to his maiden Moto2 podium at Silverstone. The Tech 3 rider had a difficult start to the session after a crash at turn one but the Mistral 610 was undamaged and he was able to continue.
Pol Espargaro went seventh fastest just before rain started to fall in the last quarter of an hour, pushing Claudio Corti down to eighth with Yuki Takahashi ninth and Alex De Angelis tenth.
Completing the British trio, Kev Coghlan spent most of the session on the fringes of the top 20 but fell back as the majority of riders went out for their second runs, ending up in 33rd.
Female wildcard entrant Elena Rosell suffered an accident and he participation in tomorrow's race is now in doubt. She finished the session 39th, ahead of Andrea Iannone, who was the only rider to fail to set a time.
