Hector Barbera declared himself 'excited' about the potential of Ducati's new 1000cc Desmosedici after testing it for the first time at Valencia on Tuesday.
The 25-year-old Spaniard, who only confirmed his deal to join the Pramac Racing squad on the morning of the test, was eighth quickest during the day, 0.3s off the quickest Ducati of Valentino Rossi.
"I am very happy with this new adventure with the Pramac Racing and the Ducati 1000cc," said Barbera. "The bike, compared to last year's one that we used in last Sunday's race has changed a lot. We can feel a lot that the engine is more powerful, and from my point of view is much more fun to ride on track.
"The new chassis improves the handling of the bike. The bike reacts much better while entering and going through the corners and this helps me a lot. The first impression is good and the bike gives me more confidence."
Barbera, who is so far the only confirmed Pramac rider for 2012, will continue testing on Wednesday.
