": I have a Mini Bike (Rupp). I'm going to make it street legal but I can't find the title. And I don't know to register it as a moped or moter cycle. My guess is moped because the engine is like a riding mower on end and has a belt to chain conection. All I know is that it will fly down the road<p>Like Kim said below, find out what the laws are in your state. Check their websites, call the DMV, whatever it takes. Laws vary from state to state, you may not need anything, and you may have to title, register, license, and pay taxes, depending on where you are. Eliminate the guesswork and find out for sure, contact your state agency for licensing info."
