Worth is up to you and values cannot be given per forum rules. Sorry. If you have time to search every day then a great deal will come. Searching your area on Craigslist, offerup, fb market, ect will give you an idea of what bikes are selling for. Here in southern California any running or at least complete mini bike selling for 250-300 is a deal that doesn't last a complete day. Put an ad in the 'WANTED' section to get more eyes on your search. Good luck on your search and don't give up!
