Believe it or not, I went to Autozone when I first bought my bike. I had just bought the bike and paid taxes and all that Jazz and thought "I'll just get a cheapie for now, and buy a good one later". Bought a $30, generic "Extra large motorcycle cover". It fits my VN900 (which is actually about the size of a V2K in terms of dimensions, the frames are very similar), along with hard bags, AND a trunk, lowers, and tall windshield just fine. Fits nice and low and snug. I've really been impressed with the quality, it's held up now without any problems for over a year, and I have no reservations about it. Unfortunately I have nowhere to park the bike inside, so it's been out there in snowstorms, thunderstorms, you name it, and held up.
Truly one of those rare 'cheap AND good' combinations.
Comes in a box like that. Picture on the box shows it goofily draped over an electra glide, but it fits over the front and rear wheel even with a big harley tour pak, hard bags and very tall windshield (adjusted all the way up).
