That's a common scam. It's still being used so it must work occasionally. Use paypal or have the money wired. No checks! It can take several weeks to verify if a check is good and you are charged if it's not. Usually the scammer follows up in a few days with a request for you to pay the party that is coming to get the bike. The party doesn't show up because they were in an accident and they make a request to get money back. Strangely they don't accept checks. Get the idea? I give a fake name and address so they have to print the fake check and overnight it to the address given. It's a small victory.
