the first 1200 mile on mine was fairly rough. the tranny started to shift faster around 800 miles and it's as smooth as I would be with a clutch now. suspension probably hasn't changed.. i think it rides smoother now, but every now and then it feels bumpy, so it's probably just my perception. They say the the tranny may be my perception too... but from several years of working on engines and transmissions, I'd say that it's not just me... the tranny seems to have a break-in period. I don't think it 'learns' the way you drive... I think that it's just a design set for the break-in period in the way the shifts are managed. And it dosen't matter if you lift your foot off the throttle or not when it shifts, so I don't bother. learned that early on too.
