Eric's answer is the short one. A "cut down" is exactly that, the frame is cut down to make it shorter and lower than stock to improve handling. the tanks were also generally shortened and modified to fit. It was a practice that generally died out by the early thirties as bikes became larger and more difficult to modify in that way. Lots of the old JD series H-Ds could run with just the magneto so the short frame wasn't a problem for electrics. Later stuff was not so easy to do. So the "cut down" became the bobber of the '30s through '50s where stripping off excess weight became the goal.
