Not sure if this one's been tossed up but just came across it surfing.

We get a must-see mention. :D
I found it from a listing of a Vision for sale but haven't come across if it's still a current listing yet or not, still browsing.
Edit: found this one:

Not in bad shape, price isn't too bad if it runs as well as advertised. Apparently the site owner is either an RoVer or just someone who's come across the site and really liked it. lol
That's a nice write up of the Vision!
If you read through the Yamahas he goes on about 'em just about every one he posts, and links the site here with each one. :)
Thinkin' I might have to look for a Kawasaki KZ1300 someday, looked like interesting bikes.
