As a rule, a bike is worth what someone else will pay. But to get a feel, you can go to some commercial sites and check. Try Kelly Blue Book, and some of the internet motorcycle sites which list high and low values.
Chuck...the longer you can wait the better......in Michigan, the first 65 degree sunny day will add $1000 to a used bike. That is nice low miles so my thought is that if you wait a little closer to spring you should be able to get MSRP or better. The accesories, as long as they are not "odd" should offset the fact that it is used and has a few miles.
