Well, we had a similar discussion some months ago. JR and I use the same
windscreen (Givi and FiveStars) and have ~ the same height, BUT JR was
claiming about the turbulences. So we found at one meeting, that JR is
sitting quite straight on his @, wereas I'm making a round back :-)) .

So it is not possible to correlate the height and the turbulences - it
always depends on the way you sit on the bike.

Have to agree. My mechanic told me the same.
