Do these helmets have the same fit? I have owned a rf1000 but never a x11. The rf fits me perfect and is very quite. The only complaint I had with it was it fogged really easy. I am going to get another shoei I just dont know which it will be.
in my experience the X-11 has a little more room......Also it provides more coverage to the chin, which is nice.
RF1000 has the same head shape as the old RF-R. Ie: longish and narrowish. Donno about the X-11, but if its the "sucsessor" helmet model, I would bet it does.
X11 seems to be a little bit bigger and the padding is a little more comfortable. I wear the same size in both helmets.
