I have a medium size Aqatex with a bulge at the back for a topbox, fits perfectly over my FZS600 with a small Givi top box (30L or thereabouts.) Unfortunately I dont think they do the Stormtex with provision for a top box, which I prefer to leave on my bike rather than take it on and off, so the Aquatex works quite well for me.

[/size]Like others have said, its quite thin. Mine has got a couple of rips in it after less than a year (and I dont think Ive been particularly rough with it), and also the strap that goes under the belly (which stops it blowing off the bike in wind) has come detached on one side. Guess I should sew it back on, or maybe hit Oxford up about a replacement since it only lasted about 6 months before that happened...

And being so thin, any part that comes in to contact with the bike will likely result in moisture seeping through, just like a tent, so beware if theres anything that needs particular protection from moisture.
Can be tricky to put on in wind because it likes to blow up like a parachute and go where ever it wants. Otherwise its nice and light and goes on and off quickly. Basically, does what it says on the tin.
[/size]I dont have a garage or anywhere undercover to keep my bike, so it gets the full weather treatment, and I do have concerns about the longevity of it. So far its holding up (just.)
