'It's always special and a great feeling to ride here,' commented Rossi, who finished third and ahead of Lorenzo in practice.
'Today was a good Friday for me, my performance was not so bad. This morning I was already quite fast but especially this afternoon my pace was very good; I was fast from the beginning to the end of practice and we are very close to the front. Yamaha has done a fantastic job with the gearbox; it is a great help for the riders. It's not a big advantage with lap time, but the bike becomes a lot easier to ride - more stable in acceleration and less wheelie. You can concentrate more on riding, it is less demanding, so I think for the race it will be a big help.'
Lorenzo also shared high praise for the gearbox, but had been suffering frustration in another form at Misano World Circuit Marco Simoncelli.
'We are having some problems to find the best setup on the bike because I felt a little bit worse than the last years here, but we are trying to improve it,' explained the reigning MotoGP World Champion.
'The new gearbox is working well and I really like it. I'm confident we can go a little faster tomorrow.'
On the timesheets, Rossi was 37 thousandths of a second quicker than Lorenzo and two and a half tenths down on pace-setter Marc Marquez. Yamaha will continue to test their seamless shift gearbox at the post-race test session on Monday.
