Andrea Locatelli was the early pace setter for Pata Yamaha before team-mate Toprak Razgatlioglu took over top spot. 

The Turkish rider’s stint at the top lasted only a few minutes though, as Scott Redding went three tenths quicker. With most of the field having returned to pit lane, Redding continued on and went even faster on used tyres. 

Locatelli closed to within half a tenth of the Ducati rider with just under ten minutes to go, while Chaz Davies enjoyed one of his strongest starts to a weekend by going sixth fastest. 

Championship contenders Rea and Razgatlioglu then went 1-2, before Redding split the pair. 

Razgatlioglu regained second spot on his penultimate lap, while fellow Yamaha rider Garrett Gerloff moved up to fourth. 

Leon Haslam suffered a late crash - the only rider to go down during FP1. 

After missing round six of the championship at Autodrom Most, Lucas Mahias made a return to action, as did Leandro Mercardo who tested positive for Covid-19 before the Czech round.
