Suzuki Alstare Brux’s Yukio Kagayama led the first World Superbike practice Friday afternoon with a lap of 1:51.356 around the 3.0-mile Outer Course at Miller Motorsports Park, but competition was tight in the session as the top 15 riders were all within one second of the best time. BMW Motorrad Motorsport’s Troy Corser showed that taking a race off was good for his injured arm as he recorded the second-best lap, a 1:51.360, late in the session on his S1000 RR. After leading most of the session, HANNspree Ten Kate Honda’s Carlos Checa slipped to third at the end with a 1:51.374 on his CBR1000RR. American Ben Spies put in fast laps at the beginning and the end of the session on his Sterilgarda Yamaha Motor Italia YZF-R1 but ended up fourth with a 1:51.378, just 0.022 second behind Kagayama. Ten Kate Honda’s Ryuichi Kiyonari was also quick through the session and finished fifth in the order with a lap of 1:51.387. In addition to Corser’s performance, the session included surprisingly strong results from Team Sterilgarda Ducati’s Shane Byrne (1:51.473) and Team Pedercini Kawasaki’s Luca Scassa (1:51.473). Xerox Ducati teammates Noriyuki Haga (1:51.799) and Michel Fabrizio (1:51.836) ended up eighth and ninth, respectively. Jamie Hacking, riding in place of Kawasaki’s injured Makoto Tamada, was 10th-fastest with a 1:51.865 on his Showa-suspended ZX-10R. Gregorio Lavilla, who is riding in place of Guandalini Racing’s injured Brendan Roberts, crashed his Ducati 1098RS in the Clubhouse Corner with about 22 minutes left in the session. He was seen walking away from the crash scene. The Superbike class will have its first qualifying session later Friday afternoon.
