MotoGP rookie Mika Kallio further underlined his potential to cause an upset in 2009 when he gained a massive 2.273sec - more than any other rider - during the second and final day of the Jerez test.

On just his fourth day as a Desmosedici rider, and third day with Bridgestone slicks, the former 250GP title contender moved forwards from eleventh out of the 14 riders on day one, to seventh on day two.

Despite being over one second slower than test leaders Valentino Rossi and Dani Pedrosa, Kallio's satellite Alice-backed GP9 was just 0.138sec behind third placed Jorge Lorenzo and a mere 0.078sec from factory Ducati rider - and 2006 MotoGP world champion - Nicky Hayden.

"It has been a good start for us," said the Finn. "Apart from Rossi and Pedrosa, that are at the moment too fast, we are only a tenth of a second from the third position occupied by Lorenzo.

"Yesterday I was a bit worried because this track was a bit too difficult with this bike, but instead today we have worked really well and we made it to achieve a good result. Of course lap times don't count so much right now, but it give us good hopes for the next season," he admitted.

Team-mate and fellow rookie Niccolo Canepa had been 0.763sec quicker than Kallio on day one, but had to settle for eleventh on day two despite gaining almost one second.

"I am very happy by the work done in these two days," said the former Ducati test rider. "Our final position is not the best but we are only half of a second from the third position and it's not too bad at this moment. I made it to improve my lap time from last year on this circuit by more than one second and a half. Today we have concentrated to find a good rhythm and I had to get used to the new rear brake positioned on the handlebar. Everything is going in the right direction."
