Scott Redding's transition to the Kalex chassis is continuing to go to plan as he topped the first day of unofficial testing at Jerez.
The Briton's will embark on his third Moto2 season with Marc VDS in 2012, but will ride a Kalex chassis having raced with Suter for the last two years.
Completing 52 laps around the Spanish circuit, though Redding suffered a fall early in the day, he was still the only rider to dip below 1min 43secs with a best time of 1min 42.9secs.
He was followed up by Pons Racing pair Pol Espargaro and Esteve Rabat and his Marc VDS team-mate Mika Kallio, who will also remain with the squad in 2012.
Having impressed in testing at Valencia recently, Gino Rea continued to make his pitch for a Gresini ride with the fifth best time, a second slower than Redding, while countryman and 2011 standout Bradley Smith was sixth quickest.
Former champion Toni Elias
was seventh best for Aspar, ahead of Axel Pons, Alex de Angelis, Yuki Takahashi, Xavier Simeon and 125GP champion Nico Terol.
