World Superbike championship leader Toprak Razgatlioglu dominated the opening free practice at Mandalika, while Jonathan Rea was only 11th fastest after being limited for track time.

An eager Razgatlioglu made his way past Leon Haslam during the early stages as he set about learning the new Mandalika track. 

Razgatlioglu’s first few laps saw him continuously lead Rea by over a second, while Isaac Vinales enjoyed an early run inside the top three.

Sectors three and four seemed to be where Razgatlioglu was making up most of his time on Rea and indeed the rest of the field during the first part of FP1.

Oliver Konig, who is replacing the injured Loris Cresson, suffered an early crash in sector three.

Michael Rinaldi and Rea were the first riders to get within a second of Razgatlioglu, with the former +0.637s down on the Pata Yamaha man. 

Razgatlioglu began his second run by going a tenth quicker to once again extend his margin over Rinaldi. The Turkish star hammered home his advantage just two laps later to lead Rinaldi by nine tenths. 

Impressive WorldSBK rookie Axel Bassani went third fastest after back-to-back low 1m 37s laps - 10 minutes to go. Michael Van Der Mark came close to a big crash at turn 15 after the rear tyre came around under braking, but luckily for the BMW rider he was able to stay aboard his BMW M 1000 RR machine.

A couple of fast laps came in from Alex Lowes late on to put him second, however, the Kawasaki rider was still seven tenths adrift of Razgatlioglu.

Lowes’ third lap significantly reduced Razgatlioglu’s lead - down to three tenths, while Vinales jumped back into third. 

But just as the gaps seemed to close up, Razgatlioglu once again went over a second clear of the rest. While Razgatlioglu was showing utter dominance around the Indonesian layout, Rea remained in pit lane due to an issue with the rear of his ZX10-RR bike. 

A stunning 1:34.985s from Razgatlioglu then put him over 1.5 seconds clear of Lowes as he was the only rider to break under the 1m 36s barrier.

Rea eventually got back out on track, however, it was too late to set a flying lap, while third in the championship Scott Redding improved late on to take fourth, behind Razgatlioglu, Lowes and Garrett Gerloff.

BMW rider Tom Sykes made his return to WorldSBK action for the first time since Catalunya after being absent for the last three rounds. This weekend is expected to be Sykes’ last in the championship ahead of a move back to BSB. 

The same situation applies to fellow Brit Haslam who will leave Honda at the end of this weekend’s inaugural race weekend in Mandalika, while 10-year veteran Chaz Davies is also competing in his final WorldSBK races ahead of retirement.
