The race win in round 6 went to American Joshua Day (Revolution Racedays Kawasaki), who became the sixth different winner this year. In a sprint finish to the line Day got the edge on Australian Jed Metcher (MTM-RT Motorsports Yamaha) and Italian Riccardo Russo (Trasimeno Yamaha), who stepped onto the podium for the first time in his debut STK600 season.

Romain Lanusse (MRS Yamaha Racing France) again failed to score a win but held off the challenge of Daniele Beretta (Trasimeno Yamaha) in the last few metres to keep his points lead intact. Brno winner Lombardi had an off day for the Martini Corse Yamaha team, the Italian finishing thirteenth and dropping to fourth in the table.
