A UK company sells these, but reckon US companies do as well. Put the bike inside, remove as much air as possible and seal.
I'm interested to hear from actual users.
Considering one for my VF500, but keeping the bike outside, with a regular cover over it as well.

Lol. I thought this was going to be the ones you store clothing in. TBH, I don't recall ever seeing something like this for a vehicle before.
I guess I'll monitor this thread and see if anyone chimes in about them. Curious to say the least.
When I had to store my bike outside for 6 months I went to an industrial plastic bag supplier and got a big bag. Rolled the bike into it, threw in a few desiccant bags and zip tied the end up.
