Work on your link... it took me to ST.N forum page.
If the cover is what I think it is (magazine advertisement) it'd be good as a 3-season garage in a low crime area for a person who rents their residence.
You'd still need a cover for travel, but this would be better at home, IMO. Much less money than a proper shed, but not as useful.
Okay, fixed the link, but not in the way I expected. I was using the url tag, and it worked when I did a preview, but when I saved and viewed the message it always had the ST.N bit in the url followed by the Motoshell url. I ended up removing the url tag figuring that readers would just have to manually enter the url. But lo and behold, it fixed it.

Anyway, yes, I am in a rental situation right now. I don't know where I'll be in September so that's why I'm looking at this. Another consideration is that next week I'll be bringing my wife's bike here so I would need two of these. So that would be $240 to $300.
Or build a temporary shed as suggested. I priced out an 8'x10' portable garage with one solid gable end and one with full width door to be about $680. That's still more than double the cost of 2 Motoshell covers, but it would give me some extra storage and work space.
I'm living in a small town so I'm not worried about vandalism. I'm just looking to give the bikes some protection from the elements. They're older bikes - the VFR is 13 and the CBR is 19 - so it's not like I have pristine, new bikes to worry about. They have battle scars, er character lines, but it's kind of sad to see them in the rain. Anyway, I may just get a tarp for now.
