Valentino Rossi was back at work today, once again testing the Ducati Desmosedici 1000cc prototype, this time at Jerez. On Tuesday and Wednesday it was test rider Franco Battaini putting the bike through its paces, while the Doctor used his seventh of eight allowable 1000cc test days today when his turn came.
Rossi arrived at the track early in the morning, and his day lasted until the final technical meetings late in the evening.
Unofficial sources claim that Valentino was concentrating on short runs of around five laps each, which could indicate that there were various solutions available for him to try. Some information has also leaked out regarding lap times,
with rumors suggesting that the Italian started his day lapping around the 1’41” area, and continued to improving throughout the session to an eventual 1’39”. As a basis for comparison, Casey Stoner's pole time from the last Jerez race was a 1'38.757, but
the Australian also tested the Honda 1000cc there in May. There were no official lap times released on that occasion either, but word of mouth put
Casey's lap times similar to those recorded by Rossi today. If true, this is positive news for Ducati, as their previous versions of the GP12 were apparently slower than the Honda equivalent at Mugello.
As with the last test session, there was no official word on the type of chassis being used, but it was almost certainly something different to the aluminum unit mounted to the GP11.1 for the recent race at Aragon. That design was fairly similar to the previous carbon fiber airbox unit, with the main differences being the construction material employed and the appearance of two braces which extended back to the seat unit. Today Rossi could have been using something similar to a Deltabox frame, or a "mixed" solution with two aluminum spars joined at the rear by the semi-stressed engine, and the rear suspension still pivoting on the motor. This compromise would actually be somewhat similar in concept to the previous Ducati trellis frames, with aluminum spars substituting the tubes.
