Michel Fabrizio maintained his place at the head of the timesheets as the second day of World Superbike testing at Imola got underway, the Italian continuing to lower his best time.
Slicing a further two tenths from the lap time that left him in charge at the end of day one, Fabrizio was the only rider to slip beneath 1min 49secs to put him four tenths up on his nearest competitor.
Surprisingly, that competition came from former Ducati Xerox rider Lorenzo Lanzi, the DFX Corse man making it an Italian 1-2 with a fine performance that proves his top ten pace on day one was by no means a fluke.
Just four thousandths of a second adrift, Jonathan Rea was third quickest on the Ten Kate Honda, ahead of Yamaha WSB pair Ben Spies and Tom Sykes.
John Hopkins was credited with making the biggest improvement between sessions on the way to the sixth fastest lap, the American going quicker than team-mate Leon Haslam for the first time since joining Stiggy Honda.
Haslam himself was eighth fastest, just behind the surprise package of the opening day Ruben Xaus, while Shane Byrne and Shinya Nakano rounded out the top ten positions.
Meanwhile, Max Neukirchner, who is still recovering from his broken leg, suffered a scare when he crashed mid-way through the session and prompted a red flag period. Taken to the medical centre, he suffered contortions to his lower back.
