Ever wondered what it might be like to sit on another bike? How it might compare to the seating position on the GTR? If you've not seen it before, check out this site and compare seating positions on various bikes:

I think it gives a really good idea of the relative seating positions, based on my old Versys, my GTR and also sitting on a variety of bikes at the bike show last year.
That gives me an idea now of what bar risers would achieve. Many thanks :)
