In Texas, it will say if it's a salvage title or not on the title. Too many people wreck bikes, and don't claim it anyways because many don't have insurance, or they don't want to jack the price of their insurance up after a claim. So they usually piece it back together and sell it with a clean title.
I can't tell you how many people have brought bikes in to my shop that they just bought with clean titles, only to find out once it's on the lift that it had been down, looped, or wrecked.
If your in the Houston area and you can get the guy to agree to bring it by my shop, I'll look it over for you free of charge.
