Andrea Dovizioso fastest in Catalunya's MotoGP test

As was the case for the entire field, the Tech 3 rider's focus was on development work rather than chasing outright laptime.

The Italian therefore spent much of his time working with Tech 3 on a new spec engine and its corresponding electronics. Dovizioso ended the day with the fastest time, a 1m41.997s, while team-mate Cal Crutchlow bounced back from a high-speed crash in the morning to go seventh fastest.

"Happy for today's work, tried new electronic and is better for the control when the grip goes down and for life of tyre, but no change on speed," Dovizioso said on Twitter. "I like Yamaha more and more..."

Yamaha's Ben Spies, whose schedule included evaluating different engine specifications and frame variations, ended the day second fastest. The American had been running well in Sunday's race, only to fall while trying to pass Honda's Dani Pedrosa for the lead.

His Yamaha stable-mate Jorge Lorenzo, winner of the grand prix, finished the day in eighth.

Honda spent much of the day evaluating Bridgestone's new front tyre, which will be made available as part of each team's pre-weekend allocation after Silverstone.

Casey Stoner and Dani Pedrosa had been first and second when the test halted for lunch, but dropped in the afternoon - Pedrosa ending one place above Stoner in fifth.

Hector Barbera, on the satellite Pramac Ducati, was third fastest ahead of Gresini Honda's Alvaro Bautista, who worked on new suspension settings.

The works Ducati squad meanwhile used the test to further trial its aluminium swingarm. Valentino Rossi had started his weekend in Catalunya using the aluminium version following a recent test at Mugello, but switched back to the carbon fibre version halfway through the weekend.

"We tried the aluminium swingarm, which could help us in terms of grip on acceleration," Rossi explained. "But it triggers too much chatter, as opposed to during the Mugello test, where it proved to be advantageous. It will be interesting to try it again at Aragon on Wednesday."

The Italian ended the day 11th fastest, just behind team-mate Nicky Hayden.
