Toprak Razgatlioglu held on to win the 10-lap sprint race at WSBK Indonesia in Mandalika by the barest of margins over Jonathan Rea.
The Yamaha rider led his teammate Andrea Locatelli early on, but Rea swept past him and then challenged Razgatlioglu for the lead on lap three, making his move stick through turns 11 and 12.
Over the next few laps, Razgatlioglu showed a relentless pace to stay with the six-time champion and beat the Kawasaki rider on the breaking going into turn 10 on lap six. The Turkish star held on to the lead to the chequered flag, with Rea just 0.5 seconds behind.
Locatelli locked up third, while riders' championship leader Alvaro Bautista could only manage fourth.
