Pretty much anything that's attached to a set of crashbars at the front...the B+B front is (at least WAS, for years) attached to the front cyl-head via a piggyback-bracket. I HAVE seen cracks in jug+head (DL650 with B+B plate) due to a serious hit. I rather write off a set of bent crashbars into the bargain than being stranded with a cracked jug out in the sticks. After all, bashplates + crashbars are "collaterals", there to be sacrificed in favour of more serious stuff. Same goes for their radiator guards etc...fantastic quality and WAYYYY too strong for the sub-structure they're attached to.
