The annual AMA Dunlop tire test started this morning at Daytona International Speedway, in Daytona Beach, Florida. Teams and riders present and planning to test are: American Honda with Miguel Duhamel and Jake Zemke; Erion Honda with Josh Hayes and Aaron Gobert; Rockwall Honda with Ryan Andrews and Ryan Elleby; Corona Extra Racing Honda with James Ellison and Gary Mason; Kawasaki with Jamie Hacking, Roger Hayden and veteran Japanese rider Akira Yanagawa; Yoshimura Suzuki with Ben Spies and Mat Mladin; Michael Jordan Motorsports Suzuki with Aaron Yates and Jake Holden; Yamaha/Graves Yamaha’s Eric Bostrom, Jason DiSalvo, Ben Bostrom and Josh Herrin; Celtic Racing Yamaha with Chaz Davies. Testing started shortly after 9:00 a.m. local time and is expected to continue through Wednesday afternoon. The local weather forecast is favorable with mild temperatures and little chance of precipitation expected over the three days. The biggest news so far is that Yoshimura Suzuki’s newest rider Tommy Hayden and the team’s 2007 GSX-R1000 Superbikes are not at the test Monday morning. Hayden is scheduled to have surgery on his fractured right wrist and possibly his broken foot at the hands of Dr. Arthur Ting today in Fremont, California, according to Hayden’s mother Rose Hayden. Tommy Hayden’s injuries are the result of a third-gear, 120 mph highside crash he suffered while testing his 2007 GSX-R1000 Superbike at Sepang, in Malaysia. The Superbikes Yoshimura Suzuki tested in Malaysia have not returned from overseas yet and were not available for testing Monday at Daytona. In the meantime, Mladin started the test on his 2006-spec Superbike (which still wears the number-one plate, much to the displeasure of 2006 AMA Superbike Champion Spies), and Spies used the time to do his first shakedown of his 2007 GSX-R1000 Superstock bike. Yoshimura Suzuki is expecting its 2007 machinery to be available on Tuesday morning. Other 2007 machinery at the test: American Honda has one 2007 Formula Xtreme CBR600RR; Erion Honda has one 2007 CBR600RR in Supersport trim; Roger Hayden and Hacking each have a 2007 ZX-6R; Eric Bostrom and DiSalvo each have a 2007 Yamaha YZF-R1 Superbike, and Ben Bostrom has a 2007 Yamaha YZF-R1 Superstock bike; and Michael Jordan Motorsports Suzuki is hoping to complete one 2007 Suzuki GSX-R1000 Superstock machine Monday morning at the track for Yates and Holden to ride. Yates, meanwhile, is riding a 2006 GSX-R1000 Superstock bike. Kawasaki’s Yanagawa is present at the test to help the team get through its share of Dunlop’s new tires and to evaluate new parts for its ZX-10R Superbike. Yanagawa, a Superbike and MotoGP veteran, tested with Kawasaki’s AMA factory team in 2006 and raced a ZX-10R in the All-Japan Superbike Championship last season.
