Some bikes sold in some states dont even have vin's cause the state may be a non-title state. Now if the frame has been chopped and stuff added, that was up to you to notice. If the bike got titled as a utah bike, chances are its either a wrecked rebuilt, a once non-titled bike that had to be registered, or its a frame up build. If the vin is clean, then dont worry about it. Its up to you though on the other stuff, you have to look it over before you pay. No one else can do that.
