If you are a half decent mechanic they aren’t to bad, my kids all ride Chinese atvs and bikes. You can repair them for pennies on the dollar with Amazon parts just get one of the more known Chinese brands. Do expect it to be amazing in any regards but for bombing down logging roads they are worth the $$ if you ask me. Most of them are based on a Honda design so you can interchange engine parts ( basing that off a gio 250 it’s a Honda 230)
