I'm interested in purchasing cheap parts bikes directly from the insurance companies after a wreck. I am mostly interested in Harleys and I don't have any interest in these gimmicky websites where you pay a fee and there are not a lot of bikes. I've looked at ebay but these are usually bikes being sold from the "person" who bought it from the insurance company (ie premium). There are some public auto auctions, but these are usually only limited to dealers. But maybe that is my only choice?

call motor cycle shops and ask.

Try going to www.crashedtoys.com They usually have quite a few.

Most major cities have Insurance Auction lots, and that is where they dispose of the bikes/vehicles claimed to be totalled in wrecks. Remember though, that there are a lot of other people who are in the business of vehicle salvage that are doing the same thing, and if it is cheap, it is "cheap". You are fighting an uphill battle here. Good luck, and maybe you want to go to Craigslist to look, or even post an ad that you are interested in buying wrecked or used bikes.
