Can someone give me a basic rundown of these bikes?

I am trying to find, of all things, a bike that meets these criteria:

1) commuter (gets gas mileage > 50 MPG)
2) track bike (doesn't have to be fast, just sporty, easy to wrench and cheap parts)
3) Better to 2-up on than my SF

I know most SV650's are nakeds, but a local school seems to have full-fairing versions and I thought it looked quite good. But other than being a V-twin I don't know much about these bikes at all.
