Katsuaki Fujiwara marked his return to World Supersport competition with an impressive run to provisional pole position at Brno.
The Japanese rider was forced to skip the previous event at Misano after contracting appendicitis, but was straight back to form around the Czech circuit as he dominated with a lap time almost a second faster than Eugene Laverty.
Having set the pace in free practice, Laverty split the Kawasakis in second place, while Joan Lascorz recovered from his fall earlier in the day to set the third best time.
A good session all round for 'Team Green', Fabien Foret – a winner for Yamaha in 2009 – was fifth best on his privateer machine, just behind Michele Pirro on the Ten Kate Honda.
David Salom was quickest for Triumph this time in sixth, ahead of Kenan Sofuoglu, the title contender making meagre gains in Q1 after struggling in free practice.
Miguel Praia continued to show top ten pace in eighth, as did Robbin Harms, who was second fastest in FP1, in ninth. Gino Rea, meanwhile, clung onto tenth despite suffering a fall in the final seconds.
