Jonathan Rea described Friday's free practice session in Indonesia as "a disaster" after struggling with tyres at the Mandalika International Street Circuit.
Rea finished fourth fastest on the rugged track which the Co Antrim rider described as "so dirty", a lot of which can be attributed to its proximity to the seaside on the Island of Lombok.
Ducati bikes finished in the top two with Michael Rinaldo Alvaro Bautista dominating the times, and Toprak Razgatlioglu next fastest.
