Troy Bayliss showed no ill effects of his cycling crash on Wednesday by finishing the opening free practice in first place onboard his Xerox Ducati.
Bayliss’ lap time of 1:40.499 is almost two seconds off the current lap record set by James Toseland last year, but the times are expected to improve as more rubber is put down on the track and the temperature increases.
Valencia race winner Noriyuki Haga showed that he is back to his best finishing second fastest.
German Max Neukirchner continued to impress by ending up in third place and top Suzuki.
Neukirchner is riding with a plated left collarbone following his final corner collision with Carlos Checa at Valencia three weeks ago.
Yukio Kagayama made it two Suzuki’s in the top four with Carlos Checa slipping down the leader board to fifth following crash at the first chicane at the end of the session.
Max Biaggi made a slow start to his weekend and ended up in 20th place. The Sterilgarda Ducati rider has recovered well from his broken wrist sustained at Phillip Island, but still only puts himself as 80 per cent for this weekend’s race.
