That return is the tightest part of the whole layout and there is no room in it for two corners and a weld.\u003c\/p\u003e\u003cp\u003eFifty millimetres is the size that section is normally built in, which is why Spark bends this diameter all the way round and stops at fourteen others.\u003c\/p\u003e\u003ch2\u003eTwo Legs, One Plane\u003c\/h2\u003e\u003cp\u003eBoth ends of a U leave in the same plane and point in opposite directions. That makes alignment simple in one axis and unforgiving in the other: rotate the piece a few degrees about its own axis and both legs move, together, in a way that is difficult to correct downstream.\u003c\/p\u003e\u003cp\u003eClock it on the motorcycle with tape before any tack goes in.\u003c\/p\u003e\u003ch2\u003eFifty-Three Euro, and What It Replaces\u003c\/h2\u003e\u003cp\u003eTwo right angles at this diameter cost seventy-six between them and need a straight, two welds and an afternoon of alignment. The U is one part, two joints instead of four, and a shape that cannot come out crooked because it was formed that way.\u003c\/p\u003e\u003cp\u003eIt is the clearest example in this range of a bought part being cheaper than the assembly it replaces.\u003c\/p\u003e\u003ch2\u003eWall Thinning Over a Full Turn\u003c\/h2\u003e\u003cp\u003eThe outer heel of a U stretches further than that of any other bend and loses more wall doing it. On a mandrel-formed part at a controlled radius that loss stays within sensible limits — but it is the reason a U should not be the section a bracket is welded to, and not the section a system hangs from.\u003c\/p\u003e\u003ch2\u003eCondensation at the Low Point\u003c\/h2\u003e\u003cp\u003eInstalled with the curve downward, a U collects water and holds it between rides. That is how a stainless system rots from the inside out on a machine used in winter. Curve uppermost where the layout allows; a small drain hole at the low point where it does not.\u003c\/p\u003e\u003ch2\u003eOrdering\u003c\/h2\u003e\u003cp\u003eOne bend per article.
