First off, you usually need a dealer license to get salvage/wrecked bike from auction... otherwise you'll have to buy them from dealerships/used sellers.

Second, you'd better be careful buying a wrecked bike. Don't do it unless you know what you're doing (which you probably don't, since you didn't know where to find said bikes). Cracked frames, bent frames (which are way more common), frames with crappy welds, rims that aren't round, seized engines, messed up clutches or transmissions etc...

These aren't cars. If your engine locks up (happened to someone I know), clutch cable breaks all of a sudden (happened to me) or wheel gets all wonky (happened to me on freakin 285) then what you do next has a direct effect on whether you coast to the side of the road safely on the bike, or something more dangerous happens.

Oh yeah.... all that stuff above? That all happened on otherwise perfectly functioning motorcycles. I would hate to have broken a clutch cable on a bike that slips gears; gotten a rear flat tire on a bike with a bent swing-arm, or locked the engine on ANY bike (broken or otherwise).

I'm not saying that a salvage bike can't be fixed (done it myself), but make sure you know what you're getting into and diligently make sure the bike gets fully inspected.

Friend of mine bought a used bike about 1.5 years ago and the seller neglected to mention TWO CRACKS IN THE FRAME. That we didn't find till after he'd bought it and brought it home (they were well) hidden by the fairings which is why he didn't see them earlier
