Havn`t used a bike helmet yet, but i know that after maybe 1.5 hours motorway driving, or like in
the picture.. 14 minutes in February. I would be happier with one.
I personally think an aeroscreen adds excitement to the experience, though after a while I do get knackered.
Originally I wanted to go for screens and side screens but now I wouldnt change it.
This time of year (rain not included) Good sunglasses, and lightweight jacket under the seat is ample
