If it is thin wall titanium I would be concerned that the motor and the mounts had damaged the frame. Geometry looks a little odd, maybe because it's a very large size?
It looks like a Litespeed stem, however need closeups of the dropout welds. Unfortunately also suspect damaged frame tubes from the engine mounts, and kickstand. What dumb a-- would use a nice frame for a motorbike?????
seatpost and stem does look ti, and maybe even the handlebar. also is the headtube oversized 1-1/4", looks much larger diameter compared the rest of the tubing.
if cheap enough, i'd say have look at possibly rescuing it, if nothing else for the parts.
