Used ATV Title

[JP11283]

So I haven't owned an ATV since I sold my Yamaha Wolverine 15 years ago. I've been thinking about picking up something used, along the lines of a 400EX, LTZ 400, maybe even a Raptor. Checked ATV Trader, seems to mainly be new bikes, not much on Craigslist. There are a decent number of ATVs on Facebook Marketplace, but it seems like very few of them have titles. Are most of these stolen? Since most of my riding will take place on public lands, a title is a must. Also, what happened to all the sport ATVs, seems no one besides Yamaha makes them anymore?
