The Supersport World Championship riders suffered some of the same issues as the Superbike riders today, with changing track conditions proving tricky and inconsistent.

Just before the rains returned in the afternoon session Luca Scassa (Yamaha ParkinGO) posted the fastest time of the day, a 1'57.074. His team-mate Chaz Davies was exactly 0.4 seconds behind and Gino Rea hopped up the order to third on his Step Racing Team Honda.

Sam Lowes (Parkalgar Honda) was fourth today but is still fastest overall thanks to his first day dry time of 1'45.845. One more day of testing remains.
