I'm 6'4" and I can't claim any problems... top up I've got plenty of room and don't hit the roof when not helmeted, when helmeted it rests on the interior fabric but I've never been bounced into the crossmember. Top down I don't believe I'm above the windscreen but my helmet is. That being said my seat is dropped as low as can be and I've got the seat pushed forward some so that I can get some rearward lean. I've put felt inbetween the seat and the plastic surround so that I can jam them together without worrying about the leather rubbing through. They did shorten the windscreen on the roadsters compared to the coupes to maintain the look.
The one thing I can complain about is that because the windscreen is shorter, the rear view mirror is right in my field of view when looking right...not bad for normal driving...easy to see behind almost without moving your eyes, horrible when on a track or driving aggressively. I tilt the mirror as far right ward as it goes so that it becomes a narrow slit of an obstruction which works very well...pain in the *** for mountain driving however as your sides are the only thing you have left to look for cops
