Yoshimura Suzuki’s Mat Mladin led the Friday morning Superbike practice time sheets, the only rider in the 1:50 bracket, with a 1:50.118.

No rider bettered their times from qualifying, but it appears that Eric Bostrom has made some progress, running within 0.3-second of his qualifying time without the use of a qualifying tire.
