crofrog has some valid points. I think those reasons are why some go with the Triumph.
A couple things he failed to mention,
wind protection, IMHO (sorry 990 fans) the 990 has virtually none.
Don't forget the side stand bracket,, if not relocated could be a spendy repair.
I'd still rather ride my 990R
