Miller: Better and better each time

Jack Miller is relishing his upgraded role at Ducati, which sees the Australian join official riders Andrea Dovizioso and Danilo Petrucci on the latest 2019 Desmosedici MotoGP machinery.

That's a jump of two years compared to the GP17 he raced for Pramac this season and also means Miller will help test new parts, such as the torque arm seen during the final test of the year at Jerez.

"There are a lot of other things around [apart from the torque arm] that we need to test more, and I think we are going to be busy boys come Sepang [in February]," said Miller, who took three front-row starts and a best race finish of fourth in his debut Ducati season.

But while the new Ducati parts grabbed a lot of attention, Miller dedicated a lot of work towards set-up, turning the GP19 'upside down'.

"We got through a lot of different set-ups and the bike seemed to work better and better with everything we tried," said the Australian, who was eighth fastest on the combined timesheets, but just 0.262s from the top.

"We turned the thing upside down and every time we tried something different, I seemed to have some positive things.

"There was really only one time, when we tried to change my position on the bike a little bit - I wasn't too happy with that so we went back. But for the rest, a lot of laps, a lot of really consistent laps, and then to put some new tyres at the end there was also nice."

Asked about the areas he wants to work on, Miller replied: "A little bit running wide. Just in a couple of places like turn 5… Also I'd really like to work on stability in the last two fast corners, as we were losing about three tenths in that last sector."

Rookie team-mate Francesco Bagnaia, who will race a GP18 next year, was ninth fastest.

Both will next be on track for the opening test of 2019, at Sepang in February.
