Hey Fudgeman: Try these guys, eztouring.com/ I've had 2 of their covers, one for my old BMW & the one I now use for the Valk. They have several sizes & they fold/roll up very small. The one I have for the Valk will fit inside my helmet when in its storage pouch.
Thx, thats what I'm looking for. A little pricey but looks good.
