[QUOTE="Monkeypants, post: 42352, member: 2708"] So can anyone explain why for sixty years we have been putting heavy rear springs in for the extra load of a passenger when in fact the passenger does not ride on the spring? They ride on those cute little solid seat stays, unless I have the wrong end of the stick, which is possible. That did happen once in 1979 or ....maybe it was 82....:D The drawing gives ratio of movement, that is a different consideration, I believe. Nothing in the drawing above shows that weight from the passenger on the seat is transferred to the springs and damper. Give it a try, it is easy to do, just try to make the spring bounce from the passenger position. At 263 lbs with gear on, I cannot with my standard Rapide. Correction, tried again with and there is tiny movement in the springs with a full on bounce from a 263 lb passenger, perhaps 1/8" max. From the rider position the same bounce nearly bottoms the springs , over ten times the movement. Glen [/QUOTE]
