The person who made the remark regarding it must be as wide as a Smart car, duh! No it isn't and you obviously don't rite an RT. Which raises the question why are you commenting?

I'm commenting because, as the owner of a R1200RT Toilet (see sig. below), i'm very aware of how wide the Panniers are (39"), as i've already collected enough scrapes on them due to filtering through traffic.
So the last thing i'd want is to make my bike even wider. However, I suppose that would be irelevent if you don't filter.......then you might as well have a Smartcar..
