Valentino Rossi's Monday test at Mugello proved something of a frustrating experience, as the Ducati star finally got his hands on some much-anticipated upgrades for the Ducati GP12 - only to miss out on valuable track time due to a technical glitch.
Updates 'to the chassis, in an effort to balance the weight distribution; to the engine, to improve rideability; and to the electronics' were all on offer.
However the full engine upgrade is not yet available and Rossi described Monday's developments as an 'intermediate step', centered around the engine management system, whilst awaiting the completion of 'substantial' changes.
“They had some things to try today, but it was mainly with an eye toward the future, as the substantial changes they're working on at Ducati for the engine's power delivery weren't ready yet,” explained Rossi.
“So this was an intermediate step, an interim engine management system through a new ECU. We started testing it this morning, and the first feelings were good, as I immediately did a good time with a used tyre.”
But the new ECU also caused the bike to stall at 4.00pm, resulting in a small fall. With the exact fault unclear, the decision was taken to end Rossi's test on safety grounds.
Rossi had completed just 23 laps, the best of which put him tenth on the timesheets, 1.130s behind Yamaha's Jorge Lorenzo.
“When I started again after the break, the bike stalled at the Correntaio and I fell,” recalled Rossi, fifth and one-second from the podium after a strong finish to Sunday's race.
“Fortunately, I was leaned over quite far at that point so I just tipped over, and nothing bad happened. In the interest of safety, we decided to stop because the engineers have to analyse the data to understand what happened.
“We also had some different parts for the chassis, but we weren't able to work with them much since we finished early. In the end, it wasn't a particularly productive day, although the first impression with this change was pretty good.”
