Eugene Laverty began his World Supersport weekend in fine style as he led an unusual looking order during first free practice at Brno.

The Irishman, who took the series lead with a fifth win of the season last time out at Misano, was top throughout the session, with his closest competition coming from some unlikely sources.

Indeed, with Kenan Sofuoglu down in eighth place and Joan Lascorz in 13th after suffering a fall 20 minutes into session, it was down to Robbin Harms to assume 'best of the rest' status in second position on his eponymous Honda.

Laverty's team-mate Miguel Praia was also impressive with a run to third position on the second Parkalgar Honda, while Katsuaki Fujiwara - sufficiently recovered from appendicitis - and '09 Brno winner Fabien Foret completed an unfamiliar top five.

Matthieu Lagrive was Triumph's top entrant in sixth, ahead of Michele Pirro and Sofuoglu, while Chaz Davies and Massimo Roccoli rounded out the top ten.

Elsewhere, Gino Rea was 11th best as he looks to give his Intermoto Czech employers a good result on home soil, while the grid has once again been given a boost by a number of wild-card entries, best of whom was Pole Daniel Bukowski in 15th.
