A lot of people are unaware of the rules/laws. From the TxDot website:
'Must I register/title my ATV or my off-highway use vehicle?
All-terrain vehicles (three or more wheels, equipped with a saddle or bench seat, and not designed by the manufacturer for farm or lawn use) are required to be titled, but not registered.
Off-highway motorcycles (two or three wheels) are required to be titled, but not registered.'

I know most people say it doesn't matter but, I'm kind of anal about it. My dirt bikes are titled. The dealer should have provided you with an MCO (manufacturer's certificate of origin, sometimes called statement of origin or MSO). That would have been what you'd take to the tax office to get a title in your name, which would be stamped "off-road use only". The cost is/was $33, which people claim is nothing but a revenue generator but, there is some peace of mind having both a legal claim to the bike, as well as a title document number/VIN in place in the event of theft. Again, most people don't care and I agree that bikes change hands numerous times without any problems whatsoever but, it's just how I am.
Dude it's a 13 yr old bike & great deal, why give em neg publicity on his post? If it's a concern send him a pm asking for vin# & call local sheriff dept & have them run # to see if it's stolen . Big diff between being anal & being real!
