Rizla Suzuki's Álvaro Bautista recorded the 11th fastest time at Motegi in Japan today, but knows there is more potential to come from rider and machine.

Bautista completed 38 laps of the 4,801m Japanese circuit, recording his quickest time of 1'48.097 on his last lap of the day. He will continue to work through a number of various set-up changes tomorrow and carry on searching for the best tyre choice, as he prepares for Sunday's race.

Álvaro Bautista:

We tested a different setting this morning and compared it against the one from Aragon. We used the new set-up in the bike with the new swinging-arm and it was definitely better. This afternoon we tried the harder option tyres, because although the softer ones were not too bad this morning, I still had a bit of movement entering the corners. This track has a lot of hard braking and the harder front tyre is much better for that because it gives me more stability. We still don't know which compound we will use for the race, so we have to test a bit more tomorrow and it will also depend on the temperature on race-day. At the end I got into a fairly good rhythm, but I still don't feel 100% with the bike. I had a little gear-shift problem and this made judging the braking points quite difficult, and I had a lot of movement because I was moving my whole body to change down a gear. We improved at the end, but not enough and I think that we can make some big steps tomorrow. With some hard work we can make the bike perform better and improve our lap-time."
