yes, definitely have someone look into if the frame is actually straight.
and find out if and or what the seller had checked out post laydown.
my accident last year on my ducati was at about 25/30mph...that bike was totaled by the insurance company.
it was a laydown of the horizontal variety (dodging an oncoming car) w/a lot of grinding involved w/the asphault and tweaking to the forks and frame.
