Once the track dried out in the afternoon, Pirelli DIABLO SUPERBIKE tires were mounted and times were steadily decreasing until Shane Byrne ran his fastest time on the 15th lap of the session, breaking Bayliss's track record of 1'43.340 by just 0.05 seconds. Ben Spies, the lone American in the superbike grid and 2008 AMA Superbike champion, began his experience with Pirelli at the very top, having posted the second best time of the day. Haga nearly equalled Spies time with just three thousandths of a gap, having made a smooth jump from Yamaha to Ducati. Pirelli and Infront Motor Sports agreed last year to a modification of the Superpole process, in which the first 20 riders from qualifying, instead of the one-lap qualifying for Superbike grid, make three 12-minute qualifying sessions in 7-minute intervals, a method which is adopted for a more exciting television broadcast. The first session will eliminate four riders, and the second session will eliminate eight, thus accounting for the first five rows of competition. This shall require more tire-strategy calculations, as riders are permitted to change tires during the intervals between the three Superpole sessions.
