Jason DiSalvo turned the fastest lap time during two days of testing at Las Vegas Motor Speedway Tuesday and Wednesday, aboard his Yamaha Superbike. The test was attended by the Yamaha Motor Corp. and Graves Yamaha AMA teams, along with Yoshimura Suzuki’s Tommy Hayden on a Supersport bike. Riders ran the Classic Course in reverse direction, using the South Extension, which meant that the paddock was on rider’s right on the front straight. DiSalvo’s best time on his Yamaha Superbike was a 1:23.21. Josh Herrin was second-fastest on his Graves Yamaha YZF-R6 Supersport bike, at 1:24.9. Ben Bostrom was third-fastest on his Graves Yamaha YZF-R6 Supersport bike, at 1:25.25, and Eric Bostrom was fourth-fastest on his Yamaha Superbike at 1:25.64. Tommy Hayden’s best lap was a 1:27.16 on his Supersport bike. Unofficial Times 1. Jason DiSalvo, Yamaha YZF-R1 (Superbike), 1:23.21 2. Josh Herrin, Yamaha YZF-R6 (Supersport), 1:24.9 3.
