Team M4 EMGO Suzuki’s Vincent Haskovec turned the fastest time in Friday’s first AMA Formula Xtreme practice session at Barber Motorsports Park, near Birmingham, Alabama. Haskovec turned a 1:28.542 on his Pirelli-equipped GSX-R600, less than a second off his own lap record time of 1:27.793. Haskovec said he used new tires Pirelli engineers recently made based on information gathered at a test his team had at Barber a few weeks ago. American Honda’s Jake Zemke (1:28.584) and Miguel Duhamel (1:30.111) were second- and third-fastest, respectively, on CBR600RRs equipped with Dunlop slicks and new-spec engines, compared with the conservative engine set-ups they ran in the Daytona 200. Fourth-fastest was Kneedraggers.com Jensen Racing’s Robert Jensen (1:30.294) on his Michelin-backed Yamaha YZF-R6. Fifth in the session was Mike Ciccotto (1:30.464) on his Pirelli-fitted Hal’s Performance Advantage Buell XB12R. Rain is in the forecast for the area of the Barber racetrack.
