"It's the hard braking where you really feel the speed of a MotoGP bike. Coming from 320km/h plus on the home straight here and trying to scrub down from sixth to second gear to make it into turn one. Your eyes are popping out!
"That's what I'm still getting used to. I need to stop panicking while I'm braking and actually think about getting into the corner rather than just stopping in time."
After spending the majority of winter testing with a base set-up, the Tech 3 team also gave Smith some new settings to try.
"We tried some different ideas, just for the team to understand what works for me. Because we rode with a base setting for four days," said the 22-year-old Englishman. "Luckily for me we preferred things more towards Dovizioso's settings. That is also useful because the team have a year's worth of data for Dovizioso's style."
In terms of the timesheet, Smith felt he's not too far from where he should be after seven days' experience of the M1. "I'm comparable with the factory Ducati guys here and in front of Iannone who is also a rookie."
The third and final pre-season test will be held at Jerez from March 23-25.
