In general, almost all new ATVs (since at least 1997) come with titles today. This is due to increased demand for titles in order to get your ATV registered and insured.

Should I buy a four wheeler without title?

Purchasing an ATV without a title is a risky business and unfortunately, it happens more often than you think. That's why it's better to purchase your ride from the dealer. If you're buying from a private sale, take precautions to protect yourself, including the creation of a Bill of Sale (more info below).

What happens if you buy a stolen ATV?

This is not only unfortunate for the original owner, but also for the unsuspecting purchaser as well. If you end up with a stolen ATV, it is most likely going to get confiscated by the police and returned to the original owner, unless you are willing to hide stolen property, which you should not.
