Yamaha’s DiSalvo Posts Top Time in First Day of Testing at Infineon Raceway SONOMA, Calif. (April 5, 2007) “” The heavy rains that have plagued motorcycle test sessions since 2001 were replaced by blue skies and 70-degree temperatures on Thursday as top AMA riders tested the twists and turns of Infineon Raceway. The teams were testing in advance of the Kawasaki AMA Superbike Showdown, presented by Supercuts, May 18-20, in the Sonoma Valley. The test featured 10 riders from Kawasaki, Honda, Yamaha and Corona Honda. All teams will return for a second day of testing on Friday, and they will be joined by Suzuki, featuring defending AMA Superbike champion Ben Spies and six-time Superbike champion Mat Mladin. As far as Superbikes go, Jason DiSalvo (Yamaha) posted the top time of the day at 1:37.22. He was followed by Honda’s Jake Zemke (1:37.30) and Miguel Duhamel (1:37.50) and Yamaha’s Eric Bostrom (1:37.62). Most riders spent the day getting reacquainted with the 12-turn, 2.22-mile road course. The two-day test session is sponsored by Yamaha. “Infineon is a track that is better suited to Yamaha and how the bike will handle,” DiSalvo said. “It’s got plenty of tight turns and flip-flops that bring out the good points in our Yamaha.” Yamaha last won a Superbike feature at Infineon Raceway in 2001 with rider Anthony Gobert. “In the morning we found a good baseline but we tried a number of different things in the afternoon and got out of our rhythm,” Zemke said. Friday will also feature Two-Wheel Thunder, a festival of sorts for race fans that will include Supermoto USA racing, SB Freaks Freestyle demonstrations and Track Talk with top AMA riders. Track officials will also make an announcement as to a rider who will be inducted into the raceway’s Wall of Fame. The Supermoto USA event, which will take place behind the main grandstand in the paddock, is a benefit for local resident Allen Yarrow of Fairfield, who has been diagnosed with cancer. Yarrow is the father of well-known rider and former District One Flatrack champion Casey Yarrow. Gates open on Friday at 9 a.m. and admission is FREE.
