BMW Motorcycle Auctions - I'm admittedly partial to BMW motorcycles, but I can safely recommend them as reliable and comfortable bikes for women motorcycle riders. The "F" series models are particularly well suited for shorter riders, because of the low seat setting and the lightweight front end.
I have known many people who have purchased motorcycles through an Ebay auction. If you are looking for a specific model, and live in a rural area, there may not be many choices near home. But, through the power of the internet, you can find various motorcycles in a certain price-range, and maybe get a great deal!
Here are the current auctions of some nice clean BMW "F" series motorcycles:
