After such an impressive debut on the ART at the first test, Laverty admitted he can't help but wonder what he may have done with that proven machine this week.
“It's a little bit frustrating because I can see they've improved the Aprilia package on Yonny's side of the garage and as a rider you always want to be chipping away and improving.
“But I'm really glad I did the first test on the ART because if this was my baptism in MotoGP and then people were seeing me seven seconds off the pace...
“At least I've had the three good days here [at the first test] and I know what I could be doing on the ART. I know we'd be competitive. We've just got some work to do with our own package now and hopefully we can get it to the level of the ART soon.”
Thursday will mark the final day of 2013 pre-season testing at Sepang, with only one further official outing at Jerez in March before the Qatar season opener.
