Casey Stoner var en halv sekund långsammare än Rossi, kort därefter kom i sin tur Colin Edwards.
Rossi om den första dagens tester;
– Today was very important because this year we have just six days of testing in which to set the bike, so we can not waste any time. This first day was very positive, we tried the new bike for 2010, with a different chassis and a new engine, which can do more kilometres, and it is quite fast.
– Yamaha has worked very well over the winter. Now we need to spend time on setting some electronics and other things. This is only the start but it seems we’re already in good shape.
