6100 miles, asking $800

It looks kind of cool. I can't tell from looking if it is a small virago type twin or a small V-max type 4 cyl... Maybe those are crash bars throwing me off on the number of pipes. Were the v-twins DOHC?

The 550 Vision handled very well, but has a weak charging system. The "weak" part is it likes to break at about 50K miles. I've owned one of this type, and liked it a LOT. It's a GREAT bike on the twisties, and gets good fuel economy. The model I had came with a front fairing, and that DID help the looks and wind control when riding.

I looked at one of these locally a few years back. Drawback is that is is a 1-year bike, finding parts is getting to be a real chore. Other than that, it got generally good reviews.

Here is a "friendly" review of the bike:
