BMW-mounted Toprak Razgatlioglu, of Turkey, overtook early leader Nicolo Bulega with 19 laps to go and had six seconds to spare over the Italian Ducati rider at the chequered flag in the opening race of the weekend, with Danilo Petrucci a further four seconds adrift in third.
Northern Ireland’s Jonathan Rea finished 10th in the first World Superbike race of the weekend at the Most circuit in the Czech Republic on Saturday.
The 38-year-old missed the first three rounds of the series in Australia, Portugal and the Netherlands as he recovered from a serious injury to his left foot sustained in a crash during testing at Phillip Island in February.
Nicolo Bulega extended his lead in the standings after snatching victory from his closest title rival Toprak Razgatlioglu with the chequered flag in sight in Race 2.
Turkey’s Razgatlioglu, who had already won both Race One and the Superpole sprint race ahead of the Italian Bulega at the Most circuit, held the lead from the 14th lap, but was pipped by 0.027 seconds.
The leading pair finished more than 16 seconds ahead of Danilo Petrucci, who rounded out the podium for the third time in the round.
Rea was involved in an incident at the first corner which brought about a yellow flag.
The six-time champion, who made his return from injury at the Italian round two weeks ago, was ultimately penalised for the collision which left Alvaro Bautista and Xavi Vierge unable to finish the race.
