So for 2up riding you would say a 6 or 7 is pretty good? About 360lbs would be on the bike.I am 200lbs.. It started off at 3 and rode like a Cadillac and I had no problem in the corners, then I rode 2 up and put it up to 7 and never changed it, its nice and firm but when I would hit a bump in the twistys it kinda scared me! So now I keep it at about 5.. I like the firmness, but wish it didnt drop so much for 2 up riding..
