The Spaniard had endured a frustrating opening day, but returned to the track on Tuesday feeling rejuventated, and it showed on the time sheets.
Lorenzo and Marc Marques where the only riders to break the two-minute barrier, with the 2013 World Champion clocking a time of 1:59,902.
“Today was much better. I was able to sleep for more than eight hours so I had much more energy than on the first day. For sure this influenced my performance," Lorenzo told the official World Superbike website.
"The bike was also better. I had a better understanding of how to ride it on slippery track conditions, so I was also able to improve my riding. My pace, apart from the last two hours, was almost all day in the 2’00 lap times. That’s similar to the previous test but with worse conditions, so I’m happy."
Testing resumes on Wednesday and concludes on Thursday.
