Oh shoot, I made a mistake on the width of the F18. I didn't realize that they weren't 8'6". What I really meant to say is that the 580 is less than 8'6". I think they are that same width you mentioned. I believe that that width may be a trailering limit in some of the countries where they are sold.

But if Cathouse is stating 8'6", then perhaps I'm totally full of it! I still believe that they are less than 8'6" because I think that is what I was told at the factory.
