The F6B cover is perfect for bone stock, maybe with the taller windshield and flat rack also.
As soon as I added the passenger backrest it starts to lose it's value and heaven forbid you actually have a bag or any kind of a trunk on the rack it is pointless. Love the little flap for the antenna, but I remove the antenna so it will not be pinched. Like that you can unzip the part over the saddlebags to get in them without removing the cover too.

I spent the princely sum of $23.76CDN for an aftermarket nylon cover that folds down to almost nothing and will only use the F6B cover for winter storage, too small, too heavy, too bulk to carry along.
