Alvaro Bautista set the pace during the first day of 2009 250cc testing, at Jerez on Monday, when the local star outpaced fellow former 125cc world champion Thomas Luthi by just over 0.3sec.

Third fastest behind the Aprilia one-two was Thai Honda rider Ratthapark Wilairot (+0.525sec), while former factory KTM rider Hiroshi Aoyama was a fraction slower in fourth on his debut for Team Scot Honda.

Another pair of 125cc world champions, Gabor Talmacsi (+1.1sec) and Mike di Meglio (+2.007sec), will be stepping up to the quarter-litre class in 2009, and the pair set the fifth and sixth fastest lap times on Monday.

Reigning 250cc world champion Marco Simoncelli was not present.
