I bought my bike from craigslist, and couldn't have been happier. Bill of Sale doesn't mean squat now, at least here in TX. They require you to have an "Application for TX Certificate of Title," proof of insurance, registration, etc. You can print that form out online. Print a few copies just in case you screw up signing it in person. Backups baby!
Even though the Bill of Sale wasn't required, I still had the owner sign it just in case. Requirements differ from state to state, so the best thing to do is check the requirements online for title transfers. Keep in mind that you're going to have to pay an additional tax on top of what the seller is selling the bike for.
One more important note. The bike I bought was co-signed by the guy and his dad. Because I didn't have the dad's signature as well, they rejected the application, and I had to have the guy mail me a new application with both signatures on it. They will NOT take a copy of the application, fresh ink only. It was a massive headache on my part, but lesson learned.
You can generally pick out the more trustworthy people on craigslist based on sentence structure, detailed pictures, and actually talking to them on the phone weeds out the suspicious.
