They are mostly called "dresser bars" (especially by the bike manufacturers) as calling them "crash bars" has negative connotations, its marketing. I do like the people in the link above calling them what people actually buy them for, in fact if buying a pair now I would probably buy those ones for being honest
My OEM dresser bars worked quite good when I crashed but are now dented and scratched up underneath they look OK at first glance though and will survive one more dumping.
